"FANTASTIC VOYAGE" Screenplay by Harry Kleiner Final December 22, 1964 REVISED - 1/15/65 REVISED - 1/18/65 REVISED - 1/19/65 REVISED - 1/22/65 REVISED - 1/26/65 REVISED - 1/27/65 REVISED - 2/1/65 REVISED - 2/2/65 REVISED - 2/5/65 REVISED - 2/23/65 Rev. 2/26/65 (NOTE: Due to the poor quality of the Xerox which I was sold, several of the pages are missing a few lines at the bottom. I have labeled these cut-offs where they occur.) FADE IN 1- OUT 3 A-3 EXT. TWA PLANE IN FLIGHT OVER LOS ANGELES - NIGHT With the myriad lights of the city beneath it. As the plane lands: B-3 EXT. HUGE HANGAR Troop carriers filled with ARMED SOLDIERS are lined up before the hangar; several official cars filled with SECRET SERVICE MEN, four MOTORCYCLE POLICEMEN, and a caravan of three limousines complete the waiting entourage. The CHIEF of the SECRET SERVICE looks toward the airfield as the plane is heard taxiing in. He turns and gets into one of the limousines, followed by the others. C-3 LONG SHOT - VEHICLES ON AIRFIELD Coming toward camera. The plane looms in the f.g. A motorized stairway is on the way toward the door of the plane. The vehicles come to a halt before the camera. D-3 HIGH ANGLE SHOT - PLANE The Armed Soldiers leap out of the troop carriers and form a cordon around the plane. The Secret Service Men get out within the circle of guards, wait for the door to open. 4 EXT. JET DOOR It opens. GRANT steps out: in middle thirties, with the air of a man who takes nothing seriously -- his coverup for involvement. He turns to help JAN BENES out of the plane. Benes is Mittel European in dress and manner. Physically, he is Schweitzer at forty: the leonine head, the shock of hair. He carries a battered suitcase. In response to Grant's gesture, he precedes him down the stairs. 5 ON THE FIELD As Benes reaches the last step, he is greeted by the Chief of the Secret Service, who shakes his hand, introduces him to several of his subordinates, and leads him to a limousine. Their words are lost in the din of jets. About to get into the car, Benes turns and moves back quickly to Grant, who is near the bottom of the stairs. Benes extends his hand. They shake warmly. Benes moves back toward the limousine. 6 GRANT - ON PLATFORM STAIRS He watches as Benes gets into the limousine and the caravan takes off with the Motorcycle Escort. The Soldiers are climbing back into the troop carriers. Grant starts down the stairs, is lost to view in the general activity. 7- OUT 8 A-8 EXT. PICO BOULEVARD Down which the cavalcade speeds. B-8 EXT. WAREHOUSE DISTRICT OF STUDIO (BACK LOT) The cavalcade races through an area of dark ware- houses. C-8 EXT. DESERTED STREET (BACK LOT) A rundown area. The cavalcade starts down the street. In the second floor of an otherwise dark house, a light is turned on and off, an evident signal. PAN DOWN to a heavy car, waiting in a narrow alley which opens into the street. Its headlights are off, the sound of its engine completely drowned by the con- certed roar of the oncoming cars and motorcycles. As the cavalcade nears the entrance to the alley, one of the motorcycles comes speeding up from the rear of the escort. The car in the alleyway starts toward the entrance to the alley. 9- OUT 15 A-15 EXT. ALLEYWAY The car starts hurtling forward at full speed. The front of the limousine is now visible. A broadside impact seems inevitable. B-15 EXT. ALLEY The motorcycle from the rear reaches the limousine as the kamikaze car comes hurtling out like a motor- ized projectile. It hits the motorcycle -- a totally unexpected obstruction -- and sends the Policeman flying out of scene. It is sufficient to deflect the kamikaze car from its deadly aim. The car hits the rear of the limousine, sends it spinning out of control. The suicide car, also out of control, careens toward the opposite side of the street. The limousine smashes into a telephone pole, which brings it to a jolting stop. 16 INT. LIMOUSINE The impact throws Benes to the side. His head hits the door handle with stunning force, almost knocking him out. 17 EXT. STREET The kamikaze car slams directly into a brick wall. It instantly bursts into fire, engulfing the Driver. The fitful flames illuminate the otherwise dark street. 18 EXT. LIMOUSINE The Chief of the Secret Service jumps out of the limousine, waves to a sedan to pull up, his shouts lost in the general turmoil. Other Secret Service Men are helping the dazed Benes out, shielding him. A sedan pulls up beside the limousine. 19 INT. SEDAN The Chief of the Secret Service instantly hustles Benes into the rear. As he climbs in beside him, and the other Secret Service Men rush to the other side to get in, there is the sharp crack of a rifle shot. It shatters the rear window of the sedan, narrowly missing Benes. The Chief thrusts him onto the floor, sprawls on top of Benes to cover him, while shouting to the Driver to get going, his words indistinguish- able in the confusion of more rifle shots, which sends glass and bullets ricocheting through the interior of the sedan. 20 EXT. STREET In the eerie light of the burning car, the sedan can be seen speeding off, flanked and spearheaded by Motorcycle Police. The Secret Service Men and those in the sedans are left behind, firing toward the top floor of a nearby building from which the rifle fire came. 21 SERIES OF IMPRESSIONISTIC CUTS THROUGH CREDITS Without divulging the nature of the hospital, the unconscious Jan Benes is seen undergoing a fast and thorough medical probe by TECHNICIANS and SPECIALISTS, using the latest equipment. Huge X-ray machines, Centrifuges whirling blood samples, EKGs, Encephalo- graphs, and a variety of instruments used in cerebral examinations are featured. After the LAST CREDIT: A-21 EXT. CITY STREET - NIGHT It is late. A car is speeding along. B-21 INT. CAR Seated in the rear, Grant looks as if he has just been aroused from sleep and hustled into the car in a hurry. He is getting into his shirt, helped by a MAN beside him. There is a smudge of lipstick on his cheek. MAN Sorry we had to get you up at this hour, Mr. Grant. GRANT (yawning) I thought I was on my vacation... What's it all about? MAN I can't tell you. GRANT Where we going? MAN I can't tell you that either... Excuse me, Mr. Grant, but you've got a smudge on your cheek. He takes out handkerchief, realizing Grant can't see it. MAN May I? GRANT Go ahead. As Grant finishes buttoning on his shirt, the Man rubs off the lipstick. Then he throws the handkerchief out of the car. GRANT What'd you do that for? MAN I'm married. GRANT And she said it was indelible... DISSOLVE TO: C-21 EXT. DESERTED WAREHOUSE - PARKING AREA - NIGHT The car bearing Grant pulls up on an unpaved parking area used for loading trucks. Nothing stirs. The DRIVER shuts off the engine and lights. D-21 INT. CAR The Driver and the Man in the rear get out. As Grant starts to follow: MAN You're to stay inside, Mr. Grant. (answering look) And wait... They close their respective doors, leaving Grant alone in the car, looking out mystified into the darkness. E-21 EXT. PARKING AREA The two men move off together, until they reach what they obviously know is a proscribed distance from the car. Then they stop and look at it. For a moment nothing happens, then the ground seemingly starts to sink with the car. F-21 INT. CAR Grant is startled to see the earth sliding up past the car. G-21 LONG SHOT - ELEVATOR SHAFT It now becomes apparent that the car has been resting on what is really the top of an elevator shaft. The sides of the shaft now become visible: it is seemingly bottom- less. H-21 INT. CAR - IN SHAFT Grant responds as the elevator finally comes to a halt. 22- OUT 39 40 INT. BOTTOM OF ELEVATOR SHAFT The car is on the earthen platform. Two big doors open. A scooter bearing the distinctive insignia of the CMDF appears, driven by an M.P. wearing the same emblem. Grant gets out of the car, is waved by the M.P. into the scooter. He gets in, is driven away. 41 INT. UNDERGROUND ORDNANCE DEPOT They pass through a vast empty area, obviously capable of holding large pieces of equipment. The insignia of the CMDF is prominent. 42- OUT 43 A-43 RAMP The scooter carrying Grant speeds up the incline to: 44 INT. CENTRAL CLEARANCE AREA MALE and FEMALE OFFICERS, all in the uniform of the CMDF, are moving about busily. As the M.P. and Grant drive across the foyer, Grant eyes the Female CMDFs apprecia- tively. Their uniforms emphasize non-military points. The scooter reaches: 45 INT. CLEARANCE DESK The OFFICER behind the desk looks up. OFFICER Your I.D. card, please. Grant takes out a card with only an embossed number. The Officer places it into an IDENTIFIER. We see its screen is blank. After a moment, Grant's picture flashes on in color, in full view and profile. The Officer looks up at Grant, sees it is an exact likeness. He then extracts the card. The screen goes blank. He hands Grant the I.D. card. The scooter takes off, speeding down a long neon-lit corridor, marked off for scooter traffic: four lanes, two in each direction. Numerous doors leading to offices open on both sides of the walkways. Traffic is heavy. Grant is the only one in mufti. The scooter approaches doors over which lights flash: MEDICAL DIVISION AUTHORIZED PERSONNEL ONLY ONLY ONLY! As the scooter nears the Sentry Box, the M.P. on duty hits a switch. The steel doors slide open. The scooter goes through into: 46- OUT 50 51 INT. MEDICAL FOYER GENERAL ALAN CARTER is coming out of a door in a hurry. The scooter bearing Grant pulls up beside him. Grant gets out. They shake hands. CARTER Hello, Grant. Good to see you again. GRANT The Pentagon, wasn't it, General? Only you weren't in that uniform... Too preoccupied to elucidate, Carter leads him through a nearby door into: 52 INT. OBSERVATION ROOM They move to window overlooking the OPERATING ROOM, see the unconscious Benes being wheeled in for Surgery. His head is uncovered. The full shock of hair stands out against the white pillow. His body is draped in the usual manner. A battery of SPECIALISTS and MEDICAL ATTENDANTS, MALE and FEMALE, are moving about under the glare of beams focused on the Operating Table. GRANT (startled) Benes... What the devil happened? CARTER The Other Side got to him. GRANT How bad off is he? CARTER Brain injury. GRANT Before or after what he wanted to tell you? CARTER Before he could breathe a word. He's the only scientist who knows the answer to what we're after. That's why we have to operate -- He turns away from the window, moves toward another door, with Grant following. CARTER -- and why we need you. GRANT Me? Bewildered, he follows Carter through door into: 53- OUT 55 56 INT. MONITORING ROOM Carter moves to a panel of many switches and TV screens. GRANT I can't even put a Band-Aid on my finger. CARTER Here's the Surgeon. He flicks a switch. On the TV screen appears the INTERIOR OF DUVAL'S OFFICE. We see DUVAL, a brain surgeon in the middle forties. He has the manner of one totally dedicated to his work. At the moment, he is testing a ruby laser, narrowing the beam down to pencil-like thinness. Assisting him is CORA PETERSON. In the middle twenties, her attractiveness is matched by her efficiency, which is considerable. They work together smoothly, the result of long association. It is evident neither know they are being observed during: CARTER Duval. Dr. Peter Duval. Top brain man in the country. Ever hear of him? GRANT Sorry, but I'm rusty on surgeons. Who's the girl? CARTER Cora Peterson, his Technical Assistant. You'll join Duval and the others -- GRANT What can I do? Except maybe pass out? Carter flips on another switch. On the TV screen appears the INTERIOR OF DR. MICHAELS' OFFICE. It is dominated by big blowups of the Circulation System. Michaels is assembling charts, as if under pressure. CARTER'S VOICE (on loudspeaker) Mike... Michaels moves to a wall, presses a switch. His TV screen shows Grant and Carter. MICHAELS Yes, Alan. CARTER Meet Grant. This is Dr. Michaels, Chief of the Medical Section. MICHAELS Glad to have you with us, Mr. Grant. GRANT Wish I knew why. CARTER Tell him where he fits in, will you? I've got a few things to check out. He moves to another panel, is seen throwing on switches, monitoring a fast series of scenes, all of which are indistinguishable in angle of shot. Michaels is seen bustling about, collecting charts during: MICHAELS We need you for Security purposes, Mr. Grant. GRANT At an operation? MICHAELS They know they failed to kill Benes. Security thinks they'll try again, first chance they get. We're afraid of medical sabotage -- or surgical assassination. GRANT Surgical assassination?! But that means you suspect -- CARTER (re-entering scene) [LINE OF DIALOGUE CUT OFF] MICHAELS I don't agree. Just because he's often difficult -- CARTER Difficult? He's impossible! MICHAELS That's no reason to suspect him of disloyalty. GRANT But why take the chance, when there must be other doctors? CARTER We have no choice. Duval's the most skillful brain surgeon in the country, and he's right here, at hand. GRANT I wouldn't know if he's trying to save him or kill him. MICHAELS I'll be standing by. I'll know. CARTER (to Grant) And no matter what happens, you're to take orders only from Dr. Michaels, understand? GRANT Right, sir. CARTER Come along, they'll be operating shortly. (hand on switch) See you later, Mike. Michaels waves. Carter switches off the monitor. He moves to a door. Grant follows. 57- OUT 61 62 INT. MEDICAL FOYER As they emerge: GRANT His technician okay? In addition to the Looks Department? CARTER No question of her loyalty. As Carter leads Grant to the scooter and they take their places, Grant looks at the big CMDF insignia on the floor. GRANT I don't mean to be inquisitive. But this CMDF -- for all I know it could stand for Consolidated Mobilization of Female Delinquents? CARTER (matter-of-fact) Combined Miniature Deterrent Forces. GRANT (blankly) Say that again? Carter starts the scooter and they drive through the big doors leading out of the Medical Foyer. 63- OUT 74 75 INT. CORRIDOR - TRAVELING WITH SCOOTER CARTER We can reduce anything down to any size we want. People -- ships -- tanks -- planes... GRANT General, I've heard some wild ones. But this takes it. CARTER We can shrink an Army -- with all its equipment -- and put it in a bottle cap. That's why we call it Combined Miniature Deterrent Forces. GRANT (with silent whistle) If the Other Side ever gets hold of a thing like that... CARTER They have... (answering look) But we've both got the same problem -- lack or control. We can only keep things Miniaturized for exactly sixty minutes. After that, every- thing starts growing back to its original size. They arrive at the root of the escalator, leave the scooter and board the moving stairway. 76 WITH ESCALATOR As they ride up: GRANT I assume Benes knows how to control it. CARTER That's right. He wanted us to have the secret, and not them. Which is why they tried to kill him. GRANT They're bound to try again. No wonder they want me to stand by during the operation. CARTER And take a little trip with them... GRANT (bewildered) Trip? Where to? CARTER (matter-of-fact) Well, the only way to reach that clot is from inside the Brain. So we've decided to put a Surgical Team and a Crew into a submarine -- reduce it way down in size, and inject it into an Artery -- GRANT (jolted) You mean I'm going along? CARTER As part of the Crew. GRANT Wait a minute! They can't shrink me! CARTER (assuringly) Grant, our Miniaturizer can shrink anything. GRANT But I don't want to be Miniaturized -- ! CARTER It's only for an hour -- GRANT Not even for a minute! General Carter, sir, I'd like you to reconsider your choice. I'm just not the right man for a mission of this kind. He starts walking against the direction of the escalator, thus remaining in the same place. CARTER (taking his arm) Come on, Grant. You're going to a Briefing. They have reached the top of the escalator. Nearby is a door marked: CONFERENCE ROOM Carter opens the door, waves him in. 77 INT. CONFERENCE ROOM Grant and Carter enter in the middle of what is evidently a heated argument between COLONEL DONALD REID and Duval. Reid is in the uniform of the CMDF, with a cadaceus which indicates he is the Medical Division. Also present is CAPTAIN BILL OWENS, in Naval uniform, and Michaels. Cora stands beside Duval, rather abashed, since she is the cause of the vociferous disagreement. DUVAL (irascibly) Miss Peterson volunteered to come along! REID So did every male Technician in the Unit. A woman has no place on a mission of this kind. DUVAL (brooking no rebuttal) I insist on taking my Technician. REID You'll take whoever I assign! DUVAL (angrily) Don't tell me whom I'm to work with! Not on this operation or any other! I'll do what I think is best, without any interference from anyone! Before Reid can reply: MICHAELS (diplomatically) Dr. Duval has relied on Miss Peterson for years. And since she wants to come along, I'm sure it's for the best, Dr. Reid. REID (making best of defeat) I don't agree with you -- but since you're in charge, you can do as you please. But I want to go on record as being against it. CARTER Grant -- Colonel Reid, Operation Commander. (they nod; of Michaels) You've met our Medical Chief. Grant and Michaels shake hands, in effect their first meeting vis-a-vis. CARTER This is Dr. Duval, our Head Surgeon. GRANT Oh yes, I've heard of you, Doctor. With the attitude of the completely dedicated profes- sional, Duval throws him a cursory glance, nods, sits down, quickly opens up a folder containing the latest lab reports on Benes, which he scans during: MICHAELS Miss Peterson, his Technical Assistant. GRANT (the charmer) How are you, Miss Peterson? She responds with an impersonal nod, sits down beside Duval and opens up her sheaf of lab reports, handing him the pertinent ones during: CARTER This is Captain Bill Owens, designer of an experimental submarine for the Navy's 'Oceanographic Research and Development Program.' As they shake hands: GRANT Out of your element, aren't you, Captain? OWENS Sort of. GRANT That makes two of us. CARTER Grant's uniquely qualified for this mission. He's a Communications Expert and was a Frogman during the War. Besides, he brought Benes into this country, and the fewer people who know about him, the better. At any rate, you'll find Grant invalu- able, should anything go wrong once you're under way. (to Reid) Okay, Don. REID Here's the overall Target Area... Reid presses a switch. A large anatomical map of a Brain flashes on a central screen. The ganglia and dendrites form a network, much like intersecting roads in a detailed war map. The clot is a solid obstruc- tion in the center. Grid lines cross the map vertically and horizontally as points of reference. The entire projection has a three-dimensional effect, since it is drawn in perspective. DUVAL Benes' brain...near as we can map it stereotaxically... He switches on a flashlight arrow, points to the clot. DUVAL The clot's right here... He switches off the arrow and quickly flashes it on again, this time on the edges of the map. The arrow now probes and withdraws from the base, center and top of the brain, like the animated technique of showing an attack which is repulsed at the perimeter. DUVAL Impossible to get at -- (arrow makes vertical penetration to give impression of wide cut) -- without damage to the intervening tissue...which would prove fatal to Benes. He presses another switch. A startling OVERLAY OF THE BLOOD VESSELS OF THE HEAD AND NECK appears over the anatomical drawing of the brain, encasing it. The red- colored arteries and blue-colored veins form such an intricate maze, that finding one's way through it seems virtually impossible. DUVAL The only way to reach it is via the Arterial System. Grant looks at Cora. She is busy making notes from the projected map. Owens is showing no undue reaction, apparently having been apprised. REID Phase One calls for Miniaturizing a submarine, with Crew and Surgical Team, and injecting it into the Carotid Artery. He points with the arrow to the exact spot. OWENS How small would that be? REID About the size of a microbe. GRANT Colonel, I'm sure that's quite a comfortable size, but -- REID Reduced proportionately, you won't find it too strange -- GRANT All in a day's work, sure. But I was thinking of the speed of the Circulatory System. MICHAELS About forty miles an hour. GRANT Well, it seems to me if you reduce a ship to microscopic size -- and the stream remains constant -- we'd take quite a beating. OWENS (very worried) I hope you've taken that into account -- CARTER We have. REID You won't be going anywhere near that fast. We're putting Benes in deep Hypothermia -- that is, freezing him low as compatible with human life. It'll slow down his heartbeat, Circulation, and all other physical processes. Owens begins polishing his glasses, indicating his inner qualms. OWENS Even so, because of our size -- I mean lack of it -- we'll still be cruising mighty fast. We'll be smashed to bits if there's any turbulence -- MICHAELS (pointing with flashing arrow) The only danger of turbulence is in the Heart -- and we're not going through it. (flashing arrow) Once in the Carotid Artery, we'll remain in the Arterial System... until we reach the point of damage -- (flashes around clot) -- where Dr. Duval will attempt to dissolve the clot with a laser beam. After the operation, we'll return by way of the Venous System -- (coursing down with arrow) -- until we reach the base of the neck -- (arrow stops) -- where we'll be removed right here -- with a hypodermic. GRANT How will you know where the sub is, at any particular moment? REID Dr. Michaels -- our Circulatory Specialist -- will serve as your Navigator. He'll know just where you are. And you can communicate directly with us, by wireless. Besides, the sub is nuclear-powered, and we'll be tracking it just as we would any radio-active tracer. CARTER There'll be a team of Surgeons standing by. We're prepared to remove you immediately, should anything go wrong. In any event, you must be out within sixty minutes. After that, you'll be in danger of attack. GRANT Attack? Who -- or should I say what from? REID Benes' natural defenses. White Corpuscles -- Antibodies. Once you begin to grow -- and become a menace to the body -- you'll trigger them off... MICHAELS With all the unknown factors in the body, I still say risking five lives for one is something we should reconsider -- CARTER We understand your concern, but we've made our decision, Doctor. Any questions? Anybody? GRANT Just one, General... CARTER Yes? GRANT Where can I get a cab back to town? No one responds to the attempted levity. Carter rises. CARTER (to all) Proceed to the Sterilization Section. Carter and Reid move out of the room through the door. The others go out through another. 78- OUT 80 A-80 INT. CORRIDOR The five appear and stop before a cylindrical door with handles similar to those in a vault, to give the effect of a sealed chamber within. Over the door flashes: STERILIZATION SECTION The five reach the door. An electronic beam swings it open automatically. They start in. As Grant moves past the sign: GRANT How much can a man give to his country? The door swings automatically shut behind him. 81 OUT 82 INT. CONTROL TOWER A huge plastic bubble in the form of a truncated semi- circle, with glass panels overlooking areas not visible in the angle of the shot. TECHNICIANS in the uniform of the CMDF are seated at a desk-level bank of monitors, on a slightly raised platform. They are checking the numerous TV screens for focus. A cacophony of B-Beeps from the screens underscores the sense of last-minute preparations. A COMMUNICATIONS AIDE wearing headphones and throat microphone moves about. Carter crosses to the Miniaturization Control Panel. Reid goes to the window overlooking the OPERATING ROOM. Below, he can see Benes on the operating table, a towel over his head. Surgical Aides are making a last-minute check of the Thermal Blanket which encases him in three sections. Reid presses a button on the wall beside the window. REID Make the final preparations... They begin to remove the towel from Benes' head. Reid turns away from the window and crosses to the window overlooking the MAIN OPS ROOM. With him we see a huge room, bisected by a floor-to-ceiling detailed map of the entire ARTERIAL and VENOUS SYSTEM from rib-cage to skull, to simulate the body of Benes in a prone position. Grid lines mark off areas in relation to true North and South. TECHNICIANS are bustling about with charts and reports which are coming in through headphones, tele- phones, teletypes, batteries of Computers, Oscillographs, etc. Encircling the entire floor are glass-fronted booths which enclose the SPECIALISTS' POSTS. Reid turns to a Technician at the Master Control Section. REID (to Technician) Heart. The Technician flips on a switch. On a TV screen appears the INTERIOR OF THE HEART POST, one of the glass- enclosed booths looking out onto the MAIN OPS ROOM. Like all the Specialists Posts, it is concerned with its particular area and nothing else: Blowups of the Heart in great detail, X-rays of Benes' heart, its beat being recorded electronically on a huge EKG chart which fills one wall and is in constant operation via remote control. The HEART SPECIALIST is standing before the EKG chart, while a TECHNICIAN twirls dials at a panel. Reid can be seen in the closed TV circuit in the Heart Post. (As in all subsequent TV communications.) REID How's it look, Henry? HEART SPECIALIST (over TV) Holding steady at thirty-two per minute. REID (to another Technician) Respiration. The Technician flips on another switch. On a TV screen appears the INTERIOR OF THE RESPIRATION POST. Here everything relates only to the lungs. In addition to cut-away sections where each small area assumes the proportions of a detailed war map, there are banks of Benes' X-rays, lit up in panels, plus immense calibrated charts labeled INHALATION and EXHALATION, on which the rate is being electronically recorded. REID How's he doing, Jack? The Lung Specialist is seen glancing at a chart. LUNG SPECIALIST (over TV) Respiration is now six per minute... I wouldn't take him down any further. Another Technician flips switch in response to: REID Hypothermia... On a TV screen appears the INTERIOR OF THE HYPOTHERMIA POST, its walls festooned with dials recording bodily temperature, before which TECHNICIANS sit watching and making minute adjustments. The HYPOTHERMIA SPECIALIST moves along, keeping a sharp eye on the various zones labeled: CIRCULATORY, RESPIRATORY, CARDIAC, RENAL, etc. REID Any problems, Dr. Sawyer? HYPOTHERMIA SPECIALIST (over TV) No sir. We're holding him at twenty- eight degrees Centigrade. Carter enters, moves to the Control Section to join Reid. CARTER Where do we stand? REID Medical's ready. The Communications Aide with headphones moves up to them. COMMUNICATIONS AIDE They're in the Sterilization Corridor -- 83- OUT 88 89 INT. STERILIZATION CORRIDOR Bathed in eerie ultra-violet light. The five are passing down the corridor, in single file. All are dressed in khaki uniforms. Grant moves ahead of Cora. As they reach a vestibule at the end, the door swings open automatically. Grant starts to help Cora over the threshold. CORA Don't touch me. I'm sterile. Grant grins. They move into: 90 INT. MINIATURIZATION ROOM A huge parquet area, composed of white octagonal modules. In the center is the Zero Module, in red. Standing over it is a fifty-foot craft. The angle and the distance renders its details indeterminate. WHITE-CLAD TECHNICIANS wearing rubber gloves are seen working about it. As the five come into the room: CARTER'S VOICE (on loudspeaker) Please board and check all your equipment immediately. They look up, see: 91 CARTER AND REID AT WINDOW OF CONTROL TOWER - THEIR P.O.V. They can be seen, high above. 92 DOWN INTO MINIATURIZATION ROOM - FROM P.O.V. CONTROL TOWER Carter and Reid look down at the tiny figures below as they move toward: 93 THE PROTEUS - OVER THE ZERO MODULE With Grant and the others, we now get the full impact of the experimental sub at close range: sleek lines from the intake in the nose sweep over a transparent plastic bubble atop the structure, and then down to taper off at the stern under which are double vents. The sub is supported by cradles, allowing it to stand free of the module. Plastic windows in the bow afford the occupants a full view. A white-Clad Technician hands Owens a small lead box. TECHNICIAN Here's the particle, sir. OWENS Everything aboard? TECHNICIAN All squared away, sir. Carefully holding the lead box, Owens starts up the ladder, followed by Duval, then Michaels. Grant waves Cora to precede him. They reach the monk's steps above the ladder, climb upward, then one by one dis- appear through the hatch. Grant is the last one in. 94 INT. PROTEUS With Grant we see the interior. There are plastic windows in the bow. In the center is the Navigation and Communications kiosk, which contains charts, reports, and a wireless set. Four swivel chairs are spaced about the kiosk. Behind it, a ladder leads to the Conning Bubble above. Set in the rear of the kiosk is a watertight door leading into the escape hatch. Behind the kiosk is a Lab and Storage Section, not visible at the moment. No power of any kind is on -- lights or air-conditioning. The interior is illuminated by the light coming in through the plastic windows. Duval, Michaels and Cora instantly move to the kiosk and busy themselves examining the charts and reports in the numerous pigeonholes. Owens hands the lead box to Grant. OWENS Hold this... Grant takes the lead box. Owens removes a crank from the tool box, inserts it into a hole in a circular trap door which reads: DANGER ATOMIC FUEL Owens turns the crank. The lid of the trap door opens. A hollow cradle comes up. Owens then opens the lead box by undoing two butterfly screws. He removes the Seed Cage from within the box. GRANT (not relishing thought) Atomic fuel? OWENS Nothing you could see with the naked eye. But there's a micro- scopic radio-active particle inside. He puts the Seed Cage on the cradle and lowers it back beneath the floor, by reversing the crank. During the above: GRANT If it's no military secret, how can a sub run on a microscopic particle? OWENS They can't reduce nuclear fuel. But once the Reactor's Miniaturized -- along with the submarine -- a microscopic particle should emit enough energy to activate it. GRANT That's cutting it mighty close -- for a perfect fit. OWENS It should work -- theoretically. If it doesn't, the mission's off. The craft's nuclear-powered. Except for your wireless. The lid of the trap door is now level with the floor. Owens removes the crank, and taking the lead box from Grant, he puts both back into the tool box during: GRANT (looking about; admiringly) All in all, quite a canoe... OWENS Designed for Piscatorial Research -- the Spawning Habits of Deep Sea Fish. GRANT Remind me to ask you about the love life of an octopus. He moves to the wireless, sees Cora smile as she goes through the aft door. Grant begins tapping out a message. 95- OUT 96 97 INT. CONTROL TOWER A WIRELESS TECHNICIAN is writing down the message heard coming in. He tears it off his pad, hands it to the Communications Aide, who takes it to Carter. COMMUNICATIONS AIDE Test message from the Proteus, sir. (reading) 'Miss Peterson has smiled.' REID That's an auspicious sign. CARTER Confirm receiving. 98 INT. PROTEUS Grant is at the wireless, logging the incoming message. In the meantime, Owens finishes battening down the entrance hatch. Duval is studying medical reports, Michaels is spreading out the first of the Navigation Charts, a very detailed map of the Vascular System of the Neck and Head. As Owens crosses on the way to the ladder leading to the Bubble: MICHAELS Captain, how will you be able to follow my charts -- (of Bubble) -- from up there? OWENS On the Repeater. Michaels looks at him blankly. Owens flips a button up and down of a hooded device which is trained on the chart area. The small screen remains blank. OWENS Once the power's on, we'll be in direct touch. Come, I'll show you. Michaels moves with him to the ladder leading to the Bubble. Owens stops, waves him to continue. Michaels goes up the ladder. A-98 INT. CONNING BUBBLE An ultra-sophisticated set of controls, consisting of a push-button panel and an airplane-like steering wheel. The plastic affords a 360 degree view of the Miniaturi- zation Room. There is room for only one person. Owens remains on the ladder, so that only his head is within the Bubble. Owens points to the identical Repeater on the Panel. OWENS That's it... MICHAELS (of controls; ironically) Looks simple to operate. He sits down in the single seat. B-98 INT. PROTEUS Grant is moving aft. With him we hear: OWENS' VOICE (from Bubble; with pride) It actually is, although the controls are highly sophisticated. There's a button for everything -- Grant enters: 99 INT. LAB AND STORAGE SECTION Originally designed for marine research, it still shows some of its pre-adaptation structure: there is a series of glass-fronted compartments, now labeled ANTIBIOTICS, ANTI-COAGULANTS, COAGULANTS, MED OXY, etc. A wide counter runs the length of the compartment on one side, suitable for working on specimens. A Ruby Laser sits on the counter at the end, its plastic cover removed and to the side. At the other is a piece of metal on a metal base. As Grant enters, he sees Cora working with a set of very small tools, making minute adjust- ments on the laser. GRANT Bet you're pretty handy around the house... Can you cook? CORA (indicating OKY containers) We're pushing oxygen today. GRANT I'll take some Laughing Gas, ma'am. CORA (surprised) You sound as if you're not looking forward to it. GRANT Well, it's not exactly a pleasure cruise. CORA I think it's the most exciting -- (with awe) We're going to see things no one ever saw before. The actual physical process of Life itself -- not something under a microscope... Just think of it -- GRANT That's the trouble. I am. Being shrunk... CORA You may learn to like it. She has finished adjusting the laser. She now lifts Grant's hand away from the metal disc. CORA Excuse me... She presses a button on the laser. With startling suddenness, a thin pencil of light shoots out, cutting a hole through the metal instantaneously. Had Grant's hand remained, the beam would have gone right through it. GRANT For a nice young lady, you play with the damndest toys, Miss Peterson... She adjusts the intensity and thickness of the laser beam, each new one cutting different size holes through the metal during: CORA (with smile) That'll teach you where to keep your hand. GRANT Now I know... As she drills metal through again: GRANT That could be quite a lethal weapon... It could kill, not cure. CORA Not in the hands of a great surgeon like Dr. Duval. The beam of this laser can be regulated to one millionth of a millimeter. GRANT I understand you've been Dr. Duval's Assistant for quite some time... He must've snatched you out of the cradle. CORA I've been with him since I got out of school. He brought me into the CMDF, over five years ago. GRANT A long time, with one man. CORA Not working for someone like Dr. Duval -- She breaks off, realizing she may have revealed her feelings. She switches off the laser, averts looking at Grant as she fits the plastic cover over it. Into the silence, the wireless is heard as a message comes in. Grant starts back into: 100 INT. PROTEUS Thoughtful, listening to the wireless. Michaels is coming down from the Bubble. As Grant reaches the wireless, the tapping comes to an end. GRANT (loud enough for all) 'Prepare for Miniaturization'... OWENS Positions, please. And strap your- selves in. Grant and Duval begin putting on their safety harnesses, which are attached to their respective seats. Cora appears out of the aft compartment. Michaels moves toward it, a check-list in hand. He disappears within. In the meantime, Owens is busy tightening every lock- screw in evidence. 101 AT THE KIOSK Cora stops before Duval, tries to help him with the final stages of getting into the harness. DUVAL It's all right -- I can manage. She starts to leave, stops. CORA (with difficulty) Doctor... DUVAL (busy with harness) Yes, Cora. CORA I -- I want to say... She falters as he looks at her. DUVAL What is it? (anxiously) Anything wrong? CORA (the moment gone) I just wanted to thank you for taking me along. DUVAL Thank you for volunteering. She turns abruptly, gets into one of the seats and starts putting on her harness. In the meantime, Michaels appears from the aft compartment, checking off a few items on the bottom of his list as he moves quickly to the kiosk. He places the list into a pigeonhole, sits down, quickly straps on his harness. 102 WITH OWENS Everything battened down, he now checks Cora's harness, then does the same with Duval's and Michaels'. All are now sweating. Finished with Grant's harness, Owens moves quickly up the kiosk ladder leading to: 103 INT. BUBBLE Owens drops into the seat, and with the speed of much practice, slips into his harness. 104 INT. PROTEUS Grant and the others hear: OWENS' VOICE (from above, in Bubble) Okay, Mr. Grant. Tell them we're ready. As Grant begins to tap out message: 105 INT. CONTROL TOWER The message is coming in. The Wireless Technician writes it down, rips it off the pad and the Communica- tions Aide reads: COMMUNICATIONS AIDE 'Proteus reports all secured.' CARTER (to Technician) Miniaturizer... A TECHNICIAN at a panel marked MIN throws a switch. 106 INT. MINIATURIZATION ROOM What appeared to be a solid wall at the end now slowly starts to slide apart, gradually revealing: 107 THE MINIATURIZER A huge, honeycombed disc, suspended from a rail run- ning along the ceiling, begins to roll silently toward the sub. 108 INT. PROTEUS As Grant gets his first sight at what is going to shrink him, he reacts quite convinced. He glances at Duval, Michaels and Cora. They, too, are looking at the on- coming Miniaturizer, but with none of his response. They apparently have seen it before. 109 P.O.V. MINIATURIZATION ROOM - FROM CONTROL TOWER Reid and Carter are looking down at the M1niaturizer as it rolls slowly toward the sub. When the disc is directly over the sub, the Technician at the MIN panel throws a switch, instantly stopping the Miniaturizer. REID All stations stand by... A Technician presses a button. There is the SOUND of a warning claxon. 110 MAIN OPS ROOM - P.O.V. The last minute scurry, as all take their respective places. The GRID OFFICER is seen moving up to the big center grid map of the Arterial System with something in hand which we can't distinguish as yet. A-110- CUTS OF TECHNICIANS IN MAIN OPS ROOM D-110 Now all are mobile, waiting at their machines. E-110 INT. CONTROL TOWER Reid is now before the monitors, all of which are on. Carter turns from the window overlooking the Miniaturi- zation Room, looks at Reid. The latter nods in silent affirmal. Carter turns to the Communications Aide. CARTER Commence Miniaturization. COMMUNICATIONS AIDE (into throat mike) Commence Miniaturization. 111 INT. MINIATURIZATION ROOM The bottom of the Miniaturizer begins to glow with increasing intensity. Simultaneously, the modules beneath the sub also begin to light up with equal intensity. Gradually, the entire sub is encased in a blaze of incandescence. 112 INT. PROTEUS The lack of ventilation and the tension is causing Grant and the others to sweat profusely. 113 INT. CONNING BUBBLE From his vantage point, Owens can see the light of the Miniaturizer reach the peak of intensity. 114 INT. CONTROL TOWER A light flashes on the MIN panel. With Carter we see a grid on the Technician's Control Panel as it becomes activated. Two blips from the co-ordinates marked MIN DIMEN and MIN SECS flash on. Reid remains at the monitors, eyes on the charts which keep flashing on, sending Benes' temperature, heartbeat, etc. 115 OUT 116 INT. MINIATURIZATION ROOM The light is bathing the entire sub in an iridescent glow. There is a dull hum. 117 INT. PROTEUS With Grant we get the first subjective realization that the sub is shrinking: the proportions of what he can see in the Miniaturization Room are changing. He looks about him in a moment of wonder. 118 DUVAL AND MICHAELS From their vantage points at the kiosk tower, they can see a little more of the outside than Grant. They respond like scientists: with intense absorption in the process. 119 CORA She responds enthralled. 120 OWENS Up in the Bubble, he gets the unlimited view -- and he is transfixed. For now the Miniaturizer stretches far, far up, and the honeycombed light from the Miniaturizer disc seems as distant as stars. The walls of the room are barely discernible in the distance. 121 BACK TO GRANT The final subjective reaction as with him we see: 122 CONTROL TOWER - GRANT'S P.O.V. Far, far up, the windows of the tower have merged into a tiny ray of light. 123 INT. MINIATURIZATION ROOM - P.O.V. CONTROL TOWER Now with Carter we get the first objective view of the shrinking Proteus as they watch it shrink down, down, down in the center of the Zero Module, which we see is laced with intersecting lines. When the sub reaches the size of a capsule about the length of a centimeter, Carter looks down at the grid on the Technician's Control Panel. He sees the blips on the co-ordinates approach closer and closer until they finally merge into one. He looks back at: 124 OUT 125 INT. MINIATURIZATION ROOM - P.O.V. CONTROL TOWER The lights at the bottom of the Miniaturizer's disc go off. The hum stops. At this distance, the sub looks like a speck on the floor. CARTER Elevate Zero Module. 126 THE ZERO MODULE - MINIATURIZATION ROOM It starts to rise from the floor with the capsule-sub. 127 INT. PROTEUS Grant and the others respond as the vast parquet floor with its maze of hexagonal lines seemingly stretching into infinity suddenly begins dropping beneath them. The effect is that of becoming air-borne. 128 INT. BUBBLE With Owens we get the unobstructed view: everything is falling far, far below. The bottom of the Miniaturizer seems an infinite distance above. 129 THE ZERO MODULE Still rising slowly. 130 THE ZERO MODULE - P.O.V. FROM INTERIOR CONTROL TOWER The capsule-sub is now about four feet off the floor, on the Module. The Zero Module comes to a stop. 131 INT. PROTEUS - ON MODULE All are sweating more profusely, showing increasing discomfort. 132 OUT 133 INT. CONTROL TOWER Carter turns from the window, looks at Reid, who glances up from viewing the monitors. REID Okay to proceed. CARTER Phase Two. 134 INT. MINIATURIZATION ROOM A panel slides open and a precision handling device is rolled in by several WHITE-CLAD TECHNICIANS. A NURSE follows, in uniform. The machine is fourteen feet high, consists of pulleys on a tripod, which control a vertical arm angling down from a horizontal extensor. Two sets of mechanical fingers are on the vertical arm, about a foot apart. Together they act as clamps. All adjustments are controlled by various worm-gears. As the tall tripod rolls by, on the side of the base we see stamped: MIN PRECISION HANDLING, under the insignia of the CMDF. 135 INT. PROTEUS Grant and the others react to the first sight of the oncoming human beings in relation to their own reduced size: a button is immense, a shoe -- although far down from their position on the Zero Module -- is long as a city street, the heads gargantuan atop skyscraper- tall bodies. The precision handling machine itself is beyond recognition, owing to its vast proportions. 136 INT. MINIATURIZATION ROOM The tripod is eased to a stop so that its vertical arm is directly over the Proteus on the Module. A TECHNICIAN at the gear box starts turning a worm-gear control, which lowers the vertical arm toward the capsule-sub. 137 INT. PROTEUS Grant reacts as huge steel fingers at the bottom of the arm slowly slide into view. He glances at Cora and the others. They apparently know what to expect, but watch with the interest of scientists. The mechani- cal fingers slowly disappear beneath the sub. 138 INT. MINIATURIZATION ROOM The Technician maneuvers the mechanical fingers care- fully so that they slip under the cradle of the sub, in effect becoming its holding fork. Once the steel fingers are in place, the Zero Module sinks below the floor from view, while the tripod holding the Proteus is eased back. A-138 INT. CONTROL TOWER A Technician presses a switch. B-138 CYLINDRICAL AMPULE - MINIATURIZATION ROOM A glass ampule about as tall and round as a small silo starts coming up out of the floor on the Zero Module. The transparent container is filled with a clear liquid, two-thirds to the top. It rests on an encircling cork base. The lettering at the base reads: SALINE SOLUTION. 139 OUT 140 CYLINDRICAL AMPULE - P.0.V. PROTEUS Grant and the others react to what appears to be something big as an illuminating gas storage tank -- albeit filled with liquid. 141 INT. MINIATURIZATION ROOM - P.O.V. CONTROL TOWER With Carter we see the tripod with the Proteus brought to a stop close to the saline solution. 142- OUT 143 144 INT. MINIATURIZATION ROOM The Technician at the tripod moves it so that the claw holding the Proteus is directly over the water in the ampule. 145 INT. PROTEUS Grant and the others react as they see themselves suspended over what appears to be a huge lake far below, bounded by cylindrical glass walls in the distance. Reflected light bounces off the top of the water, with iridescent effect. Suddenly they begin to descend. Grant and the others react as they seem to be dropping at suicidal speed toward the water which is rushing up to meet them as if they were in a dive-bomber. Then as the surface nears: 146 INT. MINIATURIZATION ROOM Within the high walls of the ampule, the capsule-sub is deposited into the water. Despite the delicate handling: 147 INT. PROTEUS It 'hits' the water, jarring all within, as at a launch- ing from drydock. 148 INT. MINIATURIZATION ROOM The Technician now begins to maneuver the mechanical fingers out from under the sub. 149 INT. PROTEUS Grant and the others see the gigantic steel fingers sliding past the plastic windows. 150 INT. MINIATURIZATION ROOM The lifting fork is now disengaged from the sub, which floats free in the ampule. 151 INT. BUBBLE The sub is rocking none too gently on the surface of the vast glass-enclosed 'lake.' As Owens sees the ends of the immense prongs move past the bubble and continue upward: OWENS (down toward kiosk) We've got to submerge manually. Grant, open Valves One and Two on the bulkhead. 152 INT. PROTEUS Grant slips out of his harness and moves quickly to a butterfly valve marked ONE in the bulkhead. On the opposite side of the sub is a duplicate valve marked TWO. As Grant begins turning Valve One: DUVAL Here -- I'll get the other. Duval gets out of his harness and moves to the second valve. Grant watches him covertly while working at his own valve. A-152 MICHAELS As he sees the fluid rising toward the bow windows, he begins to respond with increasing fear. 153 INT. BUBBLE Owens' attention is on the gauges in the panel before him. They begin recording PRESSURE and DEPTH. The surface of the saline solution begins to flood upward. 154 INT. PROTEUS Grant and Duval at the valves, now fully open. Through the outer windows the water appears to move upward in relation to the sub, which continues submerging. A-154 MICHAELS Face sweating, his eyes reflect growing irrational terror as he stares at the rising fluid bubbling over the bow windows. 155 INT. BUBBLE As the depth gauges near the 30 mark: OWENS Close valves. 156 INT. PROTEUS Grant and Duval twist the valves shut. When both are done: GRANT Valves closed. OWENS'VOICE (from Bubble) Right. That's all for the present. As Grant and Duval move to their seats, Michaels opens his harness, slips out and hangs onto the bulkhead ledge, gasping for breath. DUVAL Doctor, what's wrong? MICHAELS I can't breathe!... I've got to get out! DUVAL It's too late now. We must go on. GRANT You'll feel better once we're underway. Michaels hangs on tighter to the bulkhead ledge, trying to control himself. MICHAELS (gasping) I -- I'm sorry... Claustrophia -- buried alive -- two days -- air raid -- England... Thought I'd gotten over it. Please -- forgive me... I'm quite all right now... He sinks back into his seat. Grant helps him with his harness. 157 INT. MINIATURIZATION ROOM We now see the sub for the first time beneath the surface of the saline solution: a small capsule submerged at an even keel, about one-fourth of the way down in the huge transparent container. The Modules on which the ampule rests now return to floor level. 158 INT. MINIATURIZATION ROOM - P.O.V. CONTROL TOWER From his vantage point above, Carter can barely see the capsule in the ampule. He glances at Reid, who looks up from the monitors and nods. CARTER (to Technician) Phase Three. The Technician presses a button on the MINI panel, activating the MIN grid. The two blips flash on again, moving down the MIN DIMEN and MIN SECS co-ordinates. 159 OUT 160 THE MINIATURIZATION ROOM Instantly the disc of the Miniaturizer trained on the ampule begins to glow again. The light is reflected on the entire surface of the saline solution. The low hum resumes. 161 INT. PROTEUS Again we first get the subjective view of the shrinking process: Grant and the others see everything rushing away into an immensity of distance. And all the time the reflected light which has illuminated the interior of the sub is diminishing. We see the reason: 162 INT. MINIATURIZATION ROOM The objective view: the ampule has shrunk way below the Miniaturizer. Its far smaller size reflects only a spark of light. The sub is now only a particle, shrinking with the ampule. The Technicians and Nurse look on, grouped at the tripod which is beyond the range of the Miniaturizer. A-162 EXT. PROTEUS As the sub shrinks to invisibility, disappearing before our eyes: 163 EXT. AMPULE AND PROTEUS In its now fully reduced size, we see the ampule is actually a glass cylinder about two inches long and half-an-inch in diameter. 164 MIN GRID - P.O.V. CONTROL TOWER With Carter we see the two blips merge and hold. Instantly the lights in the Miniaturizer go off. The hum stops. A loud CLICK is heard. All look up at: 165 CLOSEUP - ELECTRIC MINUTE RECORDER A big 60 flashes on, and holds. (NOTE: We will see the same kind of clock, in varying sizes, in every set, flashing on the passage of time in minutes, from now to the end of the picture.) 166 INT. MINIATURIZATION ROOM - P.O.V. CONTROL TOWER The Zero Module now begins to rise above floor level. The ampule, on its reduced cork base, appears very tiny from this height. CARTER (to Wireless Operator) Inform Proteus they are at Full Reduction. The Technician taps out the Proteus' call letters. All wait, tense, for a response, as the tapping stops. They react, relieved, as they hear: 167 INT. PROTEUS Grant tapping out reply. Now, for the first time, we get the microscopic view of what all see from their various vantage points, distorted through liquid and the glass walls. The light is dim, all are finding it very hard to breathe in the unventilated craft. When the incoming message stops: GRANT [LINE OF DIALOGUE CUT OFF] 168 INT. BUBBLE Owens glances at his wrist watch. Then he flips a switch. He watches the buttons on his panel. None light up. There is an anxious moment. Then the myriad lights on the panel begin to glow dully. The Minute Recorder on the panel begins to flash 59. 169 INT. PROTEUS The lights become brighter. Cora, Duval and Michaels react with relief. The ventilators come on, permitting all to breathe easier. 170 INT. BUBBLE The buttons on the panel are now aglow. Owens makes a test: he touches a button which spins his seat, with the control panel before him, in a complete 360 degree turn within the Bubble. 171 INT. CONTROL TOWER After a brief message is heard coming in: COMMUNICATIONS AIDE Proteus On-Power. With relief, Carter turns to Reid. CARTER It's all yours, Don. Reid moves from the monitors, presses a button on the Control Section. 172 INT. MINIATURIZATION ROOM As the Technicians at the tripod hear: REID'S VOICE (over loudspeaker) Phase Four. The Technicians move the tripod so that the vertical arm is brought directly over the ampule and lowered, until the two sets of mechanical fingers clamp the cylinder firmly. Then the ampule is raised a few inches from its position on the module. The reduced cork base still encases the bottom. The Nurse and a Technician move to the ampule. He holds a small instrument case. 173 AT AMPULE When they reach the clamped ampule, the Technician opens the case. The Nurse takes out a plunger. Very carefully, she begins to insert it into the top of the ampule without disturbing the liquid. She then gently pulls away the cork remaining at the base of the ampule, revealing a small opening in the center. But owing to the pressure above, the liquid does not run out. She takes a needle out of the case and carefully fits it into the nipple. We now see the ampule is actually a hypodermic syringe. 174 INT. MINIATURIZATION ROOM - P.O.V. CONTROL TOWER Ried and Carter watch as the tripod is carefully wheeled across the room. 175 THE HYPODERMIC NEEDLE - MOVING SHOT The saline solution in the cylinder is sloshing slightly, despite the great care of those moving it. 176 INT. PROTEUS The sub is being rocked, causing everyone to hold on for support. 177 INT. BUBBLE Owens is trying to keep an even keel with his controls, now in full operation. 178 INT. MINIATURIZATION ROOM As two big doors slide open for the tripod to pass through: 179 EXTREME CLOSEUP - RADIAL LINES What appears to be a myriad number of radial lines crossing each other to form tiny squares over a domed surface is revealed to be: 180 BENES' HEAD Now shaved clean, the head is grid-marked for Stereo- encephalatomic measurements. In the background, the tripod is seen being wheeled in. 181 INT. OPERATING ROOM Moving with the hypodermic needle clamped in the tripod, we now get the full impact of the set: the floor is marked off for True North and South, with latitudinal and longitudinal lines. The modern operating table is set so that Benes' head corresponds with the exact position of the Arterial Head on the big grid map in the Main Ops Room. Benes is lying under a thermal blanket, covered up to the collarbone. Thin rubber pipes lead out from the blanket to the Central Thermal Unit under the operating table, out of the way of everyone. A TEAM OF GAUZE-MASKED SURGEONS AND ASSISTANTS stand grouped around the unconscious patient. In a semi-circle at the head of the bed, beyond the head, is a series of SMALL TRACKING DEVICES resembling radio-telescopes. They are remotely controlled. The Minute Recorder, in a prominent position, now changes from 59 to 58. 182 INT. OPERATING ROOM - P.O.V. CONTROL TOWER Reid and Carter are looking on. The Communications Aide stands at his side. They see the clamped hypo rolled up to the side of Benes' head and brought to a gentle stop. 183 BENES AND HYPO A small circle marks the exact spot of the injection. A SURGICAL AIDE swabs the area with alcohol. 184 CLOSE SHOT - ACTIVATOR It is brought down mechanically by use of worm-gears on the tripod toward the plunger, engaging it. 185 INT. CONTROL TOWER Reid, watching the proceedings below: REID (to Wireless Operator) Contact Proteus -- 186 INT. PROTEUS Grant takes down the message as it comes in. When message stops: GRANT (loud enough for Owens in Bubble) Stand by for injection! Suddenly the sub begins to rock hard. All hold on. 187 INT. BUBBLE Owens is manipulating controls, trying to keep an even keel. 188 INT. OPERATING ROOM The hypodermic is being angled by the precision gears of the tripod for the exact degree of injection. When this is accomplished: 189 BIG CLOSEUP - BENES' NECK The point of the needle approaches the exact spot, which we now see is marked off by a tiny cross within the circle on the Artery. 190 TECHNICIAN AT TRIPOD He presses the mechanical activator which sends the needle plunging into Benes' neck O.S. 191 INT. CONTROL TOWER Instantly a warning klaxon goes off. It keeps on for a few seconds, then stops. Into the silence: REID Tracking. A Technician flips a switch. 192 INT. TRACKING POST - ON MAIN MONITOR IN CONTROL TOWER Four TECHNICIANS are seated before their radar screens, which show flat electronic lines, except one. This is picking up a blip. A-192 INT. CONTROL TOWER A Technician at the Control Panel throws on a switch. Another TV screen next to the Main Monitor goes on, revealing: B-192 CLOSE SHOT - BLIP ON TV SCREEN Duplicating the blip seen in the Tracking Post. We see the blip is heading down, at an angle identical with that of the hypo. CAMERA MOVES IN on the blip, and keeps moving until it fills our entire screen and becomes: 193 EXT. PROTEUS - WITHIN THE HYPO Diving at a terrific speed, steeply angled like the hypo, through the clear saline solution. 194 INT. PROTEUS All hold on as if riding a roller coaster at its steepest plunge. Suddenly all goes pitch-dark. 195 INT. BUBBLE Only the buttons are glowing, and the Minute Recorder, which now reads 57. Owens throws a switch. Through the plastic windows the headlights of the sub are seen coming on. They pierce the darkness sufficiently to catch the side of the steel wall of the needle, which is rushing past at a tremendous speed, giving the effect of an enclosed channel. The beams gradually reveal: 196 HOLE OF NEEDLE - P.O.V. BUBBLE A small aperture in the distance, barely visible. A-196 HOLE OF NEEDLE - P.O.V. PRINCIPALS IN KIOSK Grant and the others see the opening at the end of the needle becoming bigger and bigger, apparently rushing toward them with great speed. B-196 EXT. END OF NEEDLE It fills the screen, an immense aperture in relation to the tiny sub which suddenly comes shooting out of it. 197- OUT 198 199 MAIN OPS ROOM - P.O.V. CONTROL TOWER Reid and Carter observe the Grid Officer, wearing head- phones and throat mike, move up to the Arterial Map with a tiny replica of the Proteus. He places it in the center or the huge channel in the neck, which depicts the Carotid Artery. The little sub is held magnetically on the grid. The Minute Recorder now reads 56. Reid turns from the window, moves to the Map Case, which contains the same assortment of charts as in the sub's kiosk. Reid takes out an OVERLAY MAP OF THE HEAD AND NECK. He places it on a Radarscope. The blip shows it is traveling up the Carotid Artery. 200 LONG SHOT - ESTABLISHING - PROTEUS IN ARTERY The headbeams of the speeding sub reveal a world of dazzling color and beauty: the Arterial Stream. The walls of the vast amber-colored chamber are lost in the distance. Now the screen is filled with a floating wonderland: huge red corpuscles, whirling globules, platelets, particles, minuscule fragments drift with the stream, reflecting the entire spectrum of color. 201 INT. BUBBLE Owens is slowing down the sub. He gazes in awe at: 202 ARTERIAL ELEMENTS - THROUGH BUBBLE As the Proteus moves through the swirling conglomera- tions, the elements are parted, flow over the sub, bounce about it, forming new fluid galaxies in a universe of amber. And each grouping and regrouping, every mass and disc, though loosely linked, has a rhythm of its own. Thus the Corpuscular drift, the bouncing particles, the parting and the merging achieve a majestic choreography lyrical in quality, a fugue of motion. 203 INT. PROTEUS Grant and Cora, strapped in their seats, look on enthralled at the sheer beauty of the dancing wonder- world visible through the windows. Duval appears equally moved. Michaels observes with more clinical detachment. 204 INT. BUBBLE Owens has now slowed down the sub so that it moves slightly faster than the current, thus enabling him to maintain maneuverability. OWENS You may unfasten your belts... 205 INT. PROTEUS Grant, Cora and Duval quickly slip out of their harnesses, move to the bow for a maximum view of the scene. Michaels remains at the console, checking their course on the Neck and Head chart. A-205 EXT. PROTEUS - HEAD-ON SHOT Approaching camera, with the three people looking out of the bow windows in speechless wonder at what they behold. 206 OUT A-206 INT. PROTEUS - SHOOTING OVER THEIR BACKS For a moment the three gaze in silent awe at the dancing drift directly outside: nuclei are clearly visible in the cells; variegated tiny organisms sweep like cosmic dust through the orbits of the spinning globules. Their first sight of the interior world, with its beauty and rhythmic splendor has affected them deeply. Finally breaking the silence: DUVAL (quietly; as he looks on) The Medieval Philosophers were right... Man is the center of the Universe... We stand in the middle of Infinity, between Outer and Inner Space. And there's no limit to either. GRANT You mean Inner Space is endless? DUVAL Everything can be divided in half, no matter how minute. As the concept sinks in, Grant turns to look out again. Cora has never taken her eyes off what she sees through the bow windows. CORA I never...never imagined it could be anything...like this. GRANT (equally awed) I always thought it was nothing but red. DUVAL Only to the naked eye. (indicating) Those corpuscles -- carrying oxygen -- give the stream its color. But the rest of the plasma's very much like sea water. An ocean of life... GRANT Quite a piece of plumbing. MICHAELS End-to-end, a hundred thousand miles long. Grant reacts. Of something up ahead: CORA Dr. Duval -- what could those be? The sub is suddenly engulfed by a mass of very tiny discs in chain-like combinations, which blot out the rest of the stream. DUVAL (now the scientist) Never saw that. Not even under an electron-microscope. CORA They're much smaller than bacteria... MICHAELS Looks like the molecular structure of proteins. DUVAL (flatly) I don't agree. I think we ought to stop and take a sample. MICHAELS That's not the purpose of this mission. (up at Owens) Captain -- keep a straight course -- until you're in the clear. 207 INT. BUBBLE Steering by instruments, Owens remains on course, the massed discs obstructing his view. Suddenly they float off, revealing: OWENS Arterial Wall to the right! With him we see: 208 LONG SHOT - ARTERIAL WALL Barely visible in the spill of light, a smooth endothe- lial wall is seen in the distance. 209 INT. PROTEUS Michaels consults his chart, brings the co-ordinates into place over two Arteries. MICHAELS (up at Bubble) What's our speed? OWENS' VOICE (from Bubble) Fifteen knots. Michaels makes a rapid calculation with his slide rule. MICHAELS We should reach the Branching Artery in two minutes. He switches on the REPEATER. 210 INT. BUBBLE The same REPEATER device is now active on the panel, reflecting the chart on the console below, with Michaels' navigational calibrators pointing to the intersecting Artery. MICHAELS' VOICE (from below) Keep the Wall at its present distance when you turn. That'll bring you safely into the middle of the Branch. 211 EXT. PROTEUS - IN ARTERY It cruises for a moment through the dazzling elements, the Arterial Wall in the distance. Then suddenly the sub accelerates and veers off course toward the Arterial Wall. 212 INT. BUBBLE Owens reacts, tries to slow down the sub and steer it back into the middle of the channel. But the speed increases, and the sub continues being swept toward the Wall. 213 INT. PROTEUS Grant and the others respond to the ever-increasing speed and the nearing Wall. They turn to Michaels, who, too, is aware of the change. MICHAELS Captain -- correct your course -- and speed. 214 INT. BUBBLE Increasingly concerned as he works the controls and glances at the gauges: OWENS She won't respond! We're in some sort of current! 215 INT. PROTEUS Duval moves to Michaels. DUVAL (bewildered) But that isn't possible. MICHAELS Not in a sealed vessel like an Artery. (up at Owens) Captain -- something must be wrong with your controls! OWENS'VOICE (from Bubble) No -- it's a current! It's too strong -- I can't break out of it! 216 INT. BUBBLE Owens is trying to gain control of the sub. It begins to vibrate. Startled, Owens peers out, trying to determine the cause, but the beams reveal nothing ahead but an iridescent swirl of Arterial elements which bounce back the light. The buffeting increases rapidly. The Arterial Wall is clearly visible to the side, getting closer. 217 INT. PROTEUS - IN BOW Grant and Cora exchange startled looks as the membranes of the Arterial Wall suddenly become visible in the spill of light from the headbeams: its connective strands arch Gothic-like, lost in the darkness of the vaulted enclosure. The vibrations have now increased so that all must hold onto stanchions for support. 218 DUVAL AND MICHAELS Gripping the console for support. Through the plastic windows to the side they can see the Arterial Wall looming with menacing closeness. They look at each other, unable to fathom the cause of the now-greater vibrations. 219 INT. BUBBLE Owens is desperately trying to avoid a head-on collision with the Wall, but the sub won't respond to any of his manipulations. The Wall looms closer, the buffeting is worse. 220 INT. PROTEUS Smashing into the Wall directly ahead seems inevitable. Now the connective strands almost fill the windows. Cora closes her eyes, in anticipation of the fatal impact. And just when a collision appears inevitable, the sub veers, narrowly missing the cable-like strands, thick enough to support a bridge. 221 INT. BUBBLE - PARALLEL TO ARTERIAL WALL With Owens we see the sub swept close alongside the Wall. It is evident the craft is out of his control, and that whatever averted the collision has nothing to do with his attempt to steer it. The swirling mass of particles up ahead begins to part. The vibrations [LINE OF DESCRIPTION CUT OFF] 222 INT. PROTEUS Grant reacts as he sees the now-visible area ahead. GRANT Whirlpool!... Strap yourselves in! He grabs Cora, and against the buffeting, moves quickly to help her toward her seat. Duval and Michaels instantly take their seats at the console, begin getting into their harnesses. 223 LONG SHOT - THE WHIRLPOOL - P.O.V. BUBBLE Owens is appalled as in the distance, in the center of the channel, he sees what appears to be an immense liquid centrifuge rotating at great speed, the Arterial elements within it whipped about like the contents of a mixmaster. Now the buffeting is reaching its climax. The sub is inexorably approaching the rim of the whirl- pool, with Owens desperately trying to steer away from it. 224 INT. PROTEUS Duval and Michaels are in their harnesses. 225 GRANT AND CORA Slowed up by the intense buffeting, Grant is now help- ing Cora into her seat. But before he can assist her into the harness, the sub is caught in the whirlpool. The instant effect is that of a Carnival Whip. The centrifugal force flings Cora out of her seat against the bulkhead. Grant is spun around and slammed against the opposite part of the bulkhead, and then onto the floor, with stunning impact. 226 DUVAL AND MICHAELS Pinned back in their seats, unable to get out and help as they see: 227 GRANT AND CORA Helpless in the whiplike rotation, Cora is thrust from the bulkhead onto the floor. Grant manages to grab a stanchion, hold on. With his free hand he reaches out for Cora, now prone on the floor. She extends her hand, but a foot separates them. They desperately reach out to each other as the centrifugal force pulls them farther and farther apart... Grant takes the only pos- sible chance or reaching her: he lets go of the stanchion, which sends him slamming against the base of the seat. He grips the leg of the seat with one hand and grabs Cora's waist with the other, just in time to prevent her from again being flung against the bulkhead. She holds onto him with all her strength. Grant strains to maintain his grip on the leg of the seat with his free hand, which in effect holds them both against the centrifugal whipping. 228 INT. BUBBLE - TO INCLUDE WHIRLPOOL Owens, too, is thrust back in his seat, powerless to move. The sub is completely at the mercy of the whirl- pool. A gauge on the panel is registering in circles. 229 EXT. PROTEUS IN WHIRLPOOL - LONG SHOT Rotating at great speed, a tiny piece of flotsam caught in a cataclysmic force which is inexorably spinning it toward the vortex. 230 INT. SUB - CUTS OF PRINCIPALS Reacting to the ROAR of the massive turbulence and the whirling stream, which is seen through the windows. The centrifugal force keeps them pinned to their positions, with Grant holding onto Cora as before. 231 EXT. PROTEUS - NEARING VORTEX It is whipped around and down in the final circle -- and disappears through the rapidly rotating center... 232 INT. PROTEUS The steeply angled dive causes greater strain on Grant as he keeps his grip on Cora. Duval and Michaels are now thrust forward as if they were in a gondola of a shoot-the-shoots making its steepest descent. 233 INT. BUBBLE In a similarly forward-tilted position, with Owens we see the stream whipping by in a seemingly endless drop. And then ahead there suddenly appears: 234 LONG SHOT - FISSURE IN ARTERIAL WALL - P.O.V. BUBBLE An immense crack through which some red corpuscles are streaming in an eddy. 235 INT. PROTEUS From their prone positions on the floor, Grant and Cora react to the huge fissure looming through the windows. Duval and Michaels exchange looks, suddenly realizing what it signifies. Now the immense crack is directly ahead. 236 EXT. PROTEUS - FISSURE FROM WITHIN VEIN As the tiny sub is swept out into the stream, where the blue corpuscles are. Through the crack, a stream of red corpuscles are whipping by on the other side. The angle of the dive now becomes less oblique. 237 INT. BUBBLE The sub is caught in a less turbulent current, which results in its gradually losing its angle and speed, permitting Owens to steer it away from the center toward a more placid area. 238 INT. PROTEUS The sub is now level, moving much slower. Exhausted from the ordeal, Grant sees it is safe to let go of Cora. He helps her rise. She stares dazed at the bluish stream. Duval and Michaels, equally spent, begin to get out of their harnesses. A-238 EXTREME CLOSE SHOT - BENES' NECK PAN over to the Miniature Tracking Devices. B-238 TWO RADAR SCREENS - INT. TRACKING POST - MAIN OPS ROOM The blip goes from one machine to the other, where it doesn't belong. The Tracking Technician reacts, instantly presses a button. 239 INT. CONTROL TOWER A warning buzz from a TV Monitor. Reid and Carter respond to the SOUND. The Communications Aide comes over to them. COMMUNICATIONS AIDE Proteus Off Course, sir. They've picked up a blip in Quadrant 23, Level B. Reid moves quickly to the window overlooking the Main Operations Room, followed by Carter. 240 OUT 241 MAIN OPS ROOM - P.O.V. CONTROL TOWER Both see the Grid Officer below move the replica of the sub from the Carotid Artery to another channel near it within a quadrant marked 23. The channel is outlined in blue. REID (jolted) They've crossed over into the Jugular Vein! CARTER That can't be -- there's no direct connection between the two -- REID Normally not. Unless it's an Arterio- Venous Fistula -- 242 INT. PROTEUS Grant, Cora and Duval are grouped around Michaels at the chart. In the distance, the endothelial walls of the Jugular Vein are vaguely visible. GRANT (blankly) A what? MICHAELS A forced joining of an Artery and Vein. Must've happened when Benes was hurt. DUVAL Yes, a fistula too small to show up on the X-rays. CORA But big enough for us... In the stream outside, the bluish corpuscles are increasing in number. MICHAELS (up at Bubble) Captain -- head back into the Artery. 243 INT. BUBBLE As if it were a suicidal order: OWENS (brooking no argument) We could never fight that current -- it's physically impossible. MICHAELS' VOICE (from below) Then don't drift down further. OWENS I'll do what I can. As he manipulates the controls: 244 INT. PROTEUS GRANT If we can't go back, is there an alternate route? MICHAELS Yes... We can go forward on this course, but it means going directly through the Heart. 245 INT. BUBBLE Owens is appalled as he sees the route being traced on the Repeater, down the Jugular Vein toward the Heart. Before it can go any further: OWENS (alarmed) We can't do that! We decided in the Briefing -- the craft could never stand the turbulence! 246 INT. PROTEUS Michaels looks up from the chart, to the others. MICHAELS Yes, it would be a hundred times worse than the whirlpool. The others respond with grim realization of what it portends. GRANT That's just dandy. We can't go forward -- and we can't go back. MICHAELS I'm afraid there's only one thing we can do. Call off the mission. CORA (emotionally) Doctor...you can't mean that! Not when we've come this far. And if we give up, there'll be no way of saving Mr. Benes -- DUVAL Dr. Michaels is right. We have no choice. MICHAELS (to Grant) Tell them to take us out. GRANT If there's any chance -- MICHAELS (an order) Request removal, Mr. Grant. As Grant moves to the wireless: 247 INT. CONTROL TOWER Carter and Reid are looking down into the MAIN OPS ROOM at the replica of the Proteus. It is in the same position as last seen in the Jugular Vein on the big grid. REID But we have no choice! We've got to take them out! CARTER (adamantly) No... He turns away from the window as a message is heard coming in. With seeming unawareness of the incoming message, Carter looks at the Minute Recorder. It is flashing 51. CARTER We still have fifty-one minutes. Leave them in. REID But it's hopeless! They can't go back and they can't go on. I tell you there's nothing else we can do but remove them! CARTER (the final word) Not until the very last second. We must think of something... Something to save the situation. The incoming message stops. The Communications Aide takes it from the Wireless Technician. COMMUNICATIONS AIDE (reading) Proteus reports trapped in Venous System. Requests removal, sir. REID Well, there it is... What do I tell them, General? Carter turns his back on him, moves to the window, stands looking down on the OPERATING ROOM. The scene below is almost a tableau, except for the moving Miniature Tracking Devices. The Surgical Team around the table stands watching, waiting. Benes lies motionless. Reid joins Carter. As they both look down at the patient, whose only chance of life is now in their hands: CARTER (finally) Doctor...without killing him -- how long could we stop his heart? REID The less time, the better. CARTER I know that. But what's the maximum? REID In his comatose state...and every- thing slowed down...no more than sixty seconds. Carter takes out a slide rule. CARTER (as he figures) At top speed...and adjusting distance for Degree of Miniaturi- zation -- (getting answer) The sub should get through the Heart in fifty-seven seconds. REID That would give us only three seconds to revive him... CARTER What are the problems in stopping the Heart? REID Nothing -- compared to starting it up again. From the window, Carter can see the big Minute Recorder in the Operating Room flashing from 51 to 50. CARTER We're wasting time, Colonel. Let's get on with it. The decision made, Reid takes command. REID (to Technician) Heart. Technician presses monitor button. As Carter moves to the Communications Aide, the HEART POST flashes on the TV screen. REID (to Heart Post) Cardiac Red Alert -- we're stopping the Heart. CARTER (to Communications Aide) Message to Proteus. Now both give their orders simultaneously. As Reid speaks, we can see the HEART POST swing into action on the TV screen: the big X-rays of Benes light up on panels, a CATHODE TUBE recording his heartbeat becomes activated. The Heart Specialist and several Heart Technicians are seen leaving the POST. Mean- while, the Communications Aide is taking down Carter's message for transmission. CARTER REID You are heading in the An Arterio-Venous Fis- opposite direction of tula has forced the the Target Area, as a Proteus into the Venous result of crossing over System.

Stand by The Proteus will proceed for exact instructions -- to the entrance of the Right Atrium -- 248- OUT 250 251 INT. OPERATING ROOM Reid's Voice is heard as the Heart Technicians rig Benes for electric shock with a Cardio-Verter. They are removing the top third of the Thermal Blanket. When his chest is exposed, they apply electrodes to it. Then the Technicians take their places at the various Cardiac Instruments which are recording the pulse and configuration of the heartbeat. The last is visible on the big cathode tube of the Cardioscope, a replica of which was seen in the Heart Post. A-251 INT. PROTEUS All are listening to Grant reading the end of the message. GRANT -- at which point the Heart will be stopped by electric shock. CORA (into the silence) And if it should take more time to get through -- DUVAL (flatly) We can't take a second more. MICHAELS (up at Bubble) Captain -- head in the direction of the flow and drift with it. He takes out a detailed Cardiac Map. 252 INT. BUBBLE Through the Repeater, Owens can see Michaels spread out the Cardiac Map. He reacts to its great complexity. OWENS I'll never find my way through that. MICHAELS I'll guide you, once we're in the Heart. 253 EXT. PROTEUS Drifting down the Jugular Vein. 254 OUT 255 INT. MAIN OPS ROOM The Grid Officer can be seen moving the replica of the Proteus down the Jugular Vein. A-255 INT. CONTROL TOWER Carter and Reid are looking down at Benes in the OPERATING ROOM. 256 INT. OPERATING ROOM Benes is now rigged for electric shock. The Tracking Devices are concentrated on his chest. The Heart Specialist looks at the Cardioscope Screen. The big screen registers the beat of the Heart with a cathode- tube effect, each pulsation causing an electronic pattern. They are very slow, regular. The Heart Specialist nods to one of his Technicians who wears headphones. The latter presses a button. 257- OUT 260 261 INT. CONTROL TOWER A warning buzzer SOUNDS. The Communications Aide moves up to Reid and Carter at the Tracking Station Monitor and Radarscope. COMMUNICATIONS AIDE Ready for Cardiac Shock... Reid nods, acknowledging the message. As he removes the map off the Radarscope, Carter takes out an OVERLAY MAP OF THE HEART from the Map Case and places it on the Radarscope. The blip is seen progressing down the Vena Cava, leading to the entrance of the Heart. REID (pressing button) Stand by. Carter takes out a stop watch. 262 OUT 263 INT. PROTEUS Grant and the others respond as they begin to hear the SOUND of a distant boom-boom, slow and measured. It has an ominous effect. It quickly gets louder during: CORA (in awe) Listen...the Heart. MICHAELS Yes...slowed down a great deal. GRANT Sounds like heavy artillery... MICHAELS It lays down quite a barrage in a lifetime. Forty million beats. DUVAL (quietly) And every beat separates a man from [LINE OF DIALOGUE CUT OFF] 264 EXT. PROTEUS - IN VENA CAVA The SOUND of the Heart is now very loud, each measured boom like heavy artillery in a relentless barrage. The headbeams illuminate the long passage, the walls of which are lost to view. 265 INT. PROTEUS Grant and the others look on ahead, responding to the now-deafening beat, which increases as they near the source in the bluish channel. And then they react with wonder as they see: 266 LONG SHOT - TRICUSPID VALVE - P.O.V. PROTEUS In the distance, three huge membranes are billowing open, with tendrils resembling supporting strands of parachutes. 267 EXT. PROTEUS - IN THE ATRIUM The parachute-like membranes are at the end of the Atrium, the entrance of which the sub now approaches. As the membranes blossom fully, with a lovely effect, a big aperture is revealed. The dilation causes a big forward surge of the stream. 268 INT. PROTEUS All hold onto whatever is at hand as the sub is swept onward, rocking with the tidal wave. Now in the distance they can see: 269 LONG SHOT - TRICUSPID VALVE - P.O.V. PROTEUS It is beginning to close, the three membranes seemingly collapsing like three parachutes over the aperture. The boom of the beating Heart is massive, making any communication very difficult. MICHAELS (over the sound; up at Bubble) Captain! They'll stop it on the next beat! 270 INT. BUBBLE Owens at the controls, eyes on the now-closed membranes, as he hears: MICHAELS' VOICE (from below) As soon as the Valve opens again, go through and give it everything you've got! 271 TRICUSPID VALVE - P.O.V. BUBBLE The sub approaches the now seemingly solid wall. Owens steers directly to where he last saw the aperture. The closed membranes loom closer and closer, the headbeams illuminating the delicately threaded strands. Suddenly the three membranes start billowing open again. 272 THE CARDIOSCOPE SCREEN The electronic pattern is recording the beat. 273 THE CARDIO-VERTER AND TECHNICIAN He immediately presses the triggers on two electrodes held against Benes' chest. 274 AMPERE NEEDLE ON CARDIO-VERTER The needle swings over into the red zone. 275 THE CARDIOSCOPE SCREEN The electronic pattern indicating the heartbeat instantly flattens out and remains so. 276 INT. BUBBLE Owens is throwing on the full-speed-ahead control. The sound of the Heart has completely stopped. 277 EXT. EXHAUST JETS A surge from the twin jets as the sub is propelled forward with a tremendous burst of power. 278 INT. PROTEUS All hang on against the acceleration. 279 PROTEUS IN TRICUSPID VALVE As it sweeps through the now-motionless membranes which wave limply in the stream, with no life of their own. 280 INT. OPERATING ROOM A tense silence pervades. The Heart Specialist and his Technicians concentrate on the various instruments. The Surgical Team stands by, immobile. 281 TRACKING DEVICES The little cones are the only things that move in the Operating Room. As they weave back and forth: 282 STOP WATCH Calibrated in seconds. The hand is now crossing 5. 283 INT. CONTROL TOWER In the silence, Carter looks up from the stop watch in hand to check with the big radar screen. Moving across the OVERLAY MAP OF THE HEART is a blip, indicating the sub's passage. 284 OUT 285 EXT. PROTEUS - IN RIGHT VENTRICLE Racing through a subterranean channel partially illumi- nated by the headbeams: a forest of tendrils, connect- ing huge roots which are the chordae tendineae extending into the walls. The color of the stream is predomina- tely blue, and the overall effect is that of a weird wonderland. As the sub surges ahead at top speed: 286 INT. OPERATING ROOM Everyone stands rooted. 287 INT. CONTROL TOWER - HEART MAP OVERLAY ON RADAR SCREEN The blip has crossed more than half the distance. Carter and Reid look on, tense. The Proteus moves further down the Ventricle. Carter glances at his stop watch. CARTER Twenty-four seconds left... including the three to revive him. 288 OUT 289 INT. PROTEUS Michaels is anxiously scanning the way ahead for signs of an opening. There is none. OWENS' VOICE (from above) Nineteen seconds, Doctor. MICHAELS The Semi-Lunar Valve should be on our left any time now. 290 INT. CONTROL TOWER Reid and Carter are tensely watching the Heart Map Overlay, as the time runs out and the sub is nearing the end. Carter looks at the stop watch. It now shows only fifteen seconds to go, which means they must be out in twelve. 291 OUT 292 INT. OPERATING ROOM The Heart Specialist is watching the blip nearing the end of the Radar Screen, with time running out. The Heart Technician standing before the Cardio-Verter stands immobile, looking at the needle which is at Zero Amperes. 293- OUT 294 295 EXT. PROTEUS - IN RIGHT VENTRICLE Racing at top speed through the immobile forest of tendrils. 296 INT. PROTEUS Suddenly, off to the side, Grant sees a small opening, half-moon in shape. GRANT There it is! MICHAELS Fasten yourselves in. There should be a tremendous surge when the Heart starts up again. DUVAL If it does... Grant throws him a look as they quickly start to get into their harnesses. 297 INT. BUBBLE Steering for the opening, Owens glances at the Second Recorder on the panel. OWENS Eight seconds left -- 298 INT. CONTROL TOWER On edge, Reid and Carter are watching the blip on the OVERLAY MAP OF THE HEART on the Radarscope. If the sub makes it, it will be exactly in 57 seconds. There are now only six seconds left. 299 OUT 300 INT. OPERATING ROOM All are focusing on the Radarscope. Five seconds left. HEART SPECIALIST Stand by. The Technician at the Cardio-Verter is set to press the red button. 301 INT. CONTROL TOWER Carter and Reid hold their breath as they see: 302 STOP WATCH It now reads 56. 303 OUT 304 OVERLAY MAP OF THE HEART As the blip approaches the Semi-Lunar Valves, a warning buzzer SOUNDS. 305 INT. OPERATING ROOM - RED BUTTON OF CARDIO-VERTER A finger presses it. 306 PULSE RATE NEEDLE ON CARDIO-VERTER It swings over, recording the first shock. 307 CARDIOSCOPE SCREEN The cathode tube registers nothing. 308 HEART SPECIALIST AT CARDIO-VERTER Concerned, he never takes his eyes off the Cardio- scope Screen. He increases the pulse rate. 309 OUT 310 CARDIOSCOPE SCREEN It still records nothing. The Heart Technicians and the Surgical Team exchange tense looks. Again the Heart Specialist increases the pulse rate. 311- OUT 312 313 PULSE RATE NEEDLE ON CARDIO-VERTER As it swings over, recording a higher and higher output. 314 EXT. PROTEUS - IN RIGHT VENTRICLE Bathed in weird St. Elmo's fire as it keeps racing toward: 315 SEMI-LUNAR VALVE which suddenly dilates into a huge opening. And with it comes an immense surge of the stream from behind, and the first boom of the Heart. 316 EXT. PROTEUS It is swept through the Semi-Lunar Valve and into: 317 ORIFICE OF PULMONARY ARTERY - SHOOTING TOWARD SEMI-LUNAR VALVE Out of which the Proteus is thrust on a great tidal wave of the bluish stream. 318 INT. OPERATING ROOM - CARDIOSCOPE The electronic pattern is on full -- a leap of life. The Heart Specialist and the others react with relief as now the EKG and the other instruments begin record- ing Benes' return from the dead. 319 OUT 320 INT. CONTROL TOWER Reid and Carter are at the window overlooking the OPERATING ROOM. COMMUNICATIONS AIDE Proteus in Quadrant 161 Level E... They leave the window and walk over to the one where they can view the MAIN OPS ROOM. They see the Grid Officer is moving the tiny sub into the wide channel leading to the Lungs. CARTER They're in the Pulmonary Artery. REID They'll make up some time, once they get through that and reach the Pleural Cavity. (to Technician) Respiration Post... On the monitor next to Reid, a Technician flashes on the INTERIOR OF THE RESPIRATION POST. The calibrated charts marked INHALATION and EXHALATION indicate the return to breathing. REID What's his rate, Jack? LUNG SPECIALIST (over TV) Back to six per minute. Reid reaches out, knocks a cup of coffee off the Central Control Section, spilling it on his trousers. REID Damn. And I just had them cleaned. 321- OUT 322 323 EXT. PROTEUS - IN PULMONARY ARTERY It is now flowing down to its normal speed. Through the smooth endothelial walls, we see the outlines of what appears to be a maze of mammoth conduits arching above and beneath the channel through which the sub is pro- ceeding. Smaller conduits divide and subdivide from the circular immensity, to be lost in the distance. The effect is that of a multi-level series of Over and Underpasses. 324 INT. PROTEUS All are out of their harnesses. Grant, Duval and Cora are at the bow windows, looking out. Michaels is at the console, plotting their position on a detailed Map of the Lungs. GRANT I'd hate to get lost on that Freeway... DUVAL They all lead to the same place -- the Lungs. 325 INT. BUBBLE In the light of the headbeams, Owens can see the Walls becoming increasingly narrow and more transparent. He glances at his Repeater, sees the Lung Chart reflected, with the co-ordinates pinpointing their position. OWENS Doctor -- the channel's getting awful narrow. MICHAELS' VOICE (from below) We're entering a Capillary. Remain in the middle. OWENS (fascinated) The Wall's transparent... MICHAELS' VOICE (from below) It's less than one ten-thousandth of an inch thick. And porous. 326 INT. PROTEUS - AT WINDOW Grant reacts as he sees a peculiar phenomenon: the big bluish corpuscles which stream past the submarine are turning bright red the instant they impinge against the Capillary Wall. They keep moving on, in a constant flow, taking on their new color during: GRANT (amazed) Look at that...they're changing color... CORA (thrilled) Doctor -- is it possible? That we're seeing it happen before our eyes? DUVAL (quietly) Yes, Cora... We're the very first to see the living process. They both look out, too deeply moved to speak. After a moment: GRANT Mind letting me in on what's going on out there? DUVAL A simple exchange, Mr. Grant. Corpuscles releasing carbon dioxide -- the moment they touch the Wall of the Lung -- in return for oxygen coming through from the other side. GRANT Don't tell me they're refueling... DUVAL (almost in a reverie) Oxygenation... Cora turns to look at him, feeling close in this shared moment. Grant, too, is moved by Duval's manner. Michaels glances up from the Lung Map. DUVAL (still gazing out) We've known it exists -- even though we never saw it...like the structure of the Atom... But to actually behold one of the miracles of the Universe -- the engineering of the Cycle of a Breath... He is too moved to continue. MICHAELS (into the silence) Nothing miraculous about it. Just an interchange of gases. The end product of five hundred million years of Evolution. DUVAL You can't believe all that's accidental? That there isn't a Creative Intelligence at work -- Before Michaels can answer, they hear a warning buzzer SOUND in the Bubble above. 327 INT. BUBBLE The buzzer is going while a red light is flashing on the panel. Owens looks startled at: 328 PRESSURE GAUGE ON PANEL The indicator is dropping rapidly toward a red horizon- tal line delineating the danger level. Owens flicks the button off and on rapidly, as if testing the mechan- ism, but the indicator keeps dropping. He shuts off the buzzer. OWENS (imperatively) Grant. 329 INT. PROTEUS All look up toward the Bubble, at the urgency of his tone. Grant moves from the bow toward the console during: GRANT What is it, Skipper? OWENS' VOICE (from Bubble) We're losing pressure in the Flotation Tanks. Check the Manual, right over there. Grant can see him pointing to the Manual Control Section at the rear of the kiosk. GRANT Right. He moves quickly to: 330 MANUAL CONTROL SECTION Over a series of controls are numerous gauges. The indicators marked TANK RT and TANK LT show the left tank is rapidly losing pressure. GRANT (up at Bubble) The left tank's losing pressure. 331 INT. BUBBLE Owens presses a button and swivels around. With him we see: 332 P.O.V. - EXT. STERN OF PROTEUS A stream of large air bubbles is pouring out behind them. 333 INT. BUBBLE Startled, Owens presses the button which swivels him back. OWENS Grant! Get up here, quick! He starts getting out of his harness. 334 INT. PROTEUS As Grant moves toward the Bubble, he passes Duval and Cora, who are now looking toward the stern. CORA (with apprehension) Air bubbles!... Doctor -- DUVAL No danger of an embolism. At our reduced scale, they're much too minute to prove fatal to Benes. 335 INT. BUBBLE As Grant appears, Owens is slipping out of his harness. OWENS There's a short in the valve. Take over. (of controls) Steers like an airplane. Grant nods as he gets into the seat. Owens starts quickly down the kiosk, leaving Grant at the controls. 336 INT. PROTEUS Cora and Duval, at the window, watch anxiously as Owens moves to the Manual Control Panel. Michaels remains at the console, also deeply concerned. Owens opens the Circuit Panel, revealing a maze of wires and circuit breakers. Only someone with an intimate knowledge of the sub could possibly find the right one. Owens does quickly. He trips a switch, shuts the panel. He turns, sees their anxious looks. OWENS Well, that takes care of the valve. It was probably caused by that elec- tric shock. MICHAELS (to Owens) Was there any damage? OWENS Not to the valve. But we've lost too much air to make it the rest of the way. DUVAL What do you propose we do, Captain? OWENS Nothing we can do. We must have full tanks to continue. He starts up toward the Bubble, leaving the three staring at each other in consternation. 337- OUT 338 339 INT. BUBBLE As Grant slips out of the seat and Owens resumes at the controls: GRANT Any reserve air? OWENS Enough to breathe, but that's all. Grant starts down. 340 INT. PROTEUS He steps into the cabin in time to hear: DUVAL (ironically) Just a few cells away from a vast air chamber -- one of the countless Alvioli of the Lung -- and we can't get enough to fill a microscopic tank. GRANT Maybe we can... (as they look at him in bewilder- ment) Skipper, is there a snorkel on this sub? OWENS' VOICE (from Bubble) Yes, there is. GRANT (to Michaels and Duval) Could I run a tube through that Wall, without harming Benes? MICHAELS At this size, I would certainly think so. GRANT If those Corpuscles can take on air, no reason why we can't. (to Duval) All we have to do is hook up the snorkel to that air chamber you were talking about, and when Benes inhales, there should be plenty of pressure to force the oxygen into the tank. (up at Owens) How's that sound to you, Skipper? 341 INT. BUBBLE As Owens considers the possibility: OWENS It's a dangerous procedure. If I miss the timing, we could explode the tanks... But I'm willing to try it. 342 INT. PROTEUS MICHAELS Yes, by all means. We must try it. OWENS' VOICE (from Bubble) It'll be safer if everybody leaves the sub. Grant moves to the aft compartment, opens the door, goes into: 343 INT. LAB AND STORAGE SECTION As he moves to compartment containing the Underwater Gear, he is jolted by something he sees o.s. 344 LASER OVER WORKING COUNTER It is swinging loose on one hook, its plastic cover off. 345 INT. LAB AND STORAGE SECTION Grant takes a step toward it, stops. GRANT Cora! After a moment, she appears. She follows his look toward the laser, reacts aghast. GRANT Looks like you didn't batten it down too well. CORA But I did. I'm positive! Duval and Michaels appear in the doorway in time to hear: GRANT Then how come it worked loose? CORA I have no idea. DUVAL Cora, is something wrong with the laser? CORA (distraught) I don't know yet, Doctor. And I won't know until I test it. GRANT That'll have to wait until after we're refueled. As he takes out the Underwater Gear and passes it to the three: CORA (righting laser) I can't imagine how it possibly could have come loose. I distinctly recall fastening it with all four bolts -- MICHAELS It must have been jarred loose during the whirlpool. Grant and Michaels exchange looks, as if neither are satisfied with the explanation. GRANT (of gear) Well, let's get into these as quickly as possible. He leads the way out. Michaels and Duval follow. Left alone, Cora starts to unzip her jumper, revealing she is wearing her swim suit beneath. Her eyes remain on the laser, now her prime source of anxiety... A-345 INT. MAIN OPS ROOM Starting on the grid map, we see the sub in the channel of the Pulmonary Artery. CAMERA then TILTS DOWN to the Radarscope, where the blip is blinking on and off in one place, without moving. 346 INT. CONTROL TOWER On the monitor at the Map Table, we see the INTERIOR OF THE TRACKING POST, where the same blip is in the identical stationary position on the Radarscreen. PULL BACK to include Reid staring at the blip on the monitor. Carter is pacing on the other side of the table. REID They've stopped -- on the outer limits of the Right Lung... Carter looks at the Minute Recorder. It reads 42. CARTER Another delay... With only forty- two minutes left. REID It'll be close -- but there's still a margin of safety. CARTER Let's find what the devil's holding them up! (to Wireless Technician) Contact the Proteus! As the message is heard being tapped out: REID (glancing at Monitors; none are on) It must be some kind of mechanical difficulty. The tapping stops. As they wait for an answer, Carter pours a stream of sugar into his coffee. REID I told you to cut down on the sugar. CARTER I can't help it. I'm just weak, I guess. 347- OUT 349 350 INT. PROTEUS - AT DOOR OF ESCAPE HATCH All have stepped out of their jumpers and are now revealed in their swim suits except Owens, who remains in the Bubble. The suits are form-fitting, antiseptic- looking, with a Breather Pack strapped to the back. Duval is tightening Cora's pack. Grant is checking Michaels' pack. The latter looks in rear at the small hatch, visible through the open door. The wireless starts tapping again. CORA (of tapping wireless) Shouldn't you answer that? GRANT (putting on swim mask) Not now. We need air, not greetings! He motions Michaels to precede him into the hatch. Face reflecting his irrational fear, Michaels puts his swim mask over his fear. But he freezes at the door, unable to step into the small hatch. Grant and Duval exchange looks. GRANT Let's go, Doctor. Michaels forces himself into the Escape Hatch. Grant follows, closing the door. 351 INT. ESCAPE HATCH There is only space for the two. Michaels cowers against the wall, palms pressed against the metal, fighting against another seizure of his phobia. Grant opens a valve. Liquid starts pouring into the hatch from several ports. When it is up to their chins, Grant bends down to unlock the ventral hatch. 352 EXT. PROTEUS Grant drops out of the hatch. Michaels follows. Grant then closes the hatch. With Grant in the lead, they swim toward: 353 EXT. TOP OF PROTEUS Grant reaches the snorkel, looks toward Bubble. 354 INT. BUBBLE Where Owens has now swiveled so that he faces the stern. Owens sees Grant signal to proceed. Owens presses button on SNORKEL RELEASE. 355 EXT. PROTEUS The snorkel starts rising. When the tube is a few feet above the sub, Grant takes the bobbing end, holds it under one arm, and starts swimming with his free arm toward the Capillary Wall on the left. 356 EXT. SIDE OF PROTEUS As Grant swims by with the end of the unreeling tube, Michaels joins him. Then Duval and Cora, who are now coming out of the ventral hatch. All swim to the nearby Capillary Wall. (NOTE: During the following, their action is complicated by the big Corpuscles flowing by in a steady stream, taking on oxygen and bumping into them.) They reach: 357 EXT. ALVEOLAR CREVICE It shimmers with the liquid that seems to cover it like a door of reflecting glass. The opening is just large enough for all to look within. They see: 358 INT. ALVEOLUS A vast conical volcano, the upper part lost to view. Numerous outcroppings of immense crags are visible on all sides. GRANT It's full of rocks! (NOTE: During all Swimming Sequences, we will hear the Speaker's Voice only via the AUDIO PICKUP within the swimming mask of the one who responds vocally.) MICHAELS In a way - yes. Those are impurities imbedded in the Lung after a lifetime of 'Civilization.' Carbon from smoke and smog -- specks of dust -- GRANT Well, we better get on with it. He starts shoving the front of the snorkel through the vertical liquid entrance. To his startled surprise, it immediately comes flying out with great force. Michaels and Duval grab it in time to prevent the snorkel from snaking off down the stream. MICHAELS Careful! There's a tremendous air pressure in there -- in relation to our size! Grant grabs hold of the front part again. GRANT I'll try to hold it from the other side of the wall, while you push from out here. Maybe that'll do it. CORA You can't -- it's too dangerous -- MICHAELS Yes -- with all that pressure, and suction within -- GRANT There's no other way. Tie my safety line to the sub. DUVAL Here, let me have it. Grant takes out his safety line, hooks it onto his suit. Duval starts swimming with the other end back to the Proteus. 359 INT. BUBBLE Owens is eyeing the pressure gauges anxiously. He reacts as he sees: 360 EXT. PROTEUS - P.O.V. BUBBLE With Owens we see Duval is nearing the sub, the safety line strung out behind him. 361 EXT. PROTEUS - AT VENTRAL HATCH Duval hooks Grant's safety line onto a ring for the purpose, signals: 362 EXT. ALVEOLUS CREVICE Grant acknowledges signal. The Alveolar Wall can be seen dilating slightly. GRANT All right now -- push the snorkel through as soon as I get inside. MICHAELS (eyes on Wall) Walt for the lull -- between the time he inhales and exhales. As the dilating stops: MICHAELS Now! Grant pushes quickly through the shimmering entrance. 363 INT. ALVEOLUS He has literally transposed himself into another element: air. There is no turbulence, no sound. Instantly he props his feet against both sides of the entrance. The snorkel is shoved through. As he grabs it and holds, a breath is heard starting. Only Grant can hear the ensuing sound. 364 CAPILLARY SIDE OF ALVEOLUS Duval now joins Michaels and Cora. They hold against the increasing pressure from within. Grant can be seen straining on the other side against the enormous wind pressure. 365 INT. BUBBLE Owens' finger is on the button of the MASTER PRESSURE GAUGE, waiting. The indicator is quickly swinging toward FULL. 366 INT. ALVEOLUS The wind is rising to gale force. Grant is holding on with all his strength to the end of the snorkel. The others can be seen pushing from their side, to keep the tube from flying out. 367 MASTER PRESSURE GAUGE As the indicator hits the FULL position: 368 AIR TANK CONTROL BUTTON Owens' finger presses down while: OWENS' VOICE (o.s.) Full! 369 INT. ALVEOLUS In response, Grant lets go of the snorkel, which is instantly whipped out. Buffeted by the howling wind, he now tries to get out. But the hurricane causes Grant to lose his balance. He falls, slammed against the outcroppings by the force of the wind. Finally the lull comes. Instantly, Grant starts climbing back, hand over hand, using the rope as one would in scaling a mountain. The crevice is still far up ahead when suddenly a new breath starts in the upward direction. Grant is caught in the tremendous suction of the exhalation and is pulled toward the interior of the Lung. 370 SAFETY CLASP ON SUB RING The Safety Clasp breaks off at the end of the nylon. 371 EXT. ALVEOLUS CREVICE Michaels, Duval and Cora react as the line snakes past them through the crevice. CORA (horrified) He's gone! 372 INT. ALVEOLUS The suction sends Grant flying upward, past the crevice, with the safety line trailing after him. The wind whips him toward a fantastic height. Finally he hits: 373 COLUMNAR CILIA Long stalks, with a waving motion that makes it resemble a vast field of wheat. Grant is seen flying through it, until he is lost from view. Then as the wind subsides: 374 EXT. ALVEOLUS CREVICE The three are waiting, tense. DUVAL (to Michaels) What can we do? MICHAELS Nothing -- against all that force. CORA But we just can't leave him in there! What'll happen to him? MICHAELS We'll know -- in the next breath... They react as they see the Alveolar Wall starting to dilate again, signaling the advent of another breath. 375 INT. ALVEOLUS - SHOOTING UP The wind starts howling. And then Grant is seen at a vast height, plummeting down. Part of the way he hits a spongy area, bounces, is caught up again by the blasting wind, hits another spongy section, with a big outcropping of "rock." 376 EXT. OUTCROPPING Fighting the gale, he manages to snake his safety line around the big rock. As he hangs on, he sees: 377 P.O.V. - PRINCIPALS AND SUB - THROUGH CREVICE Not too far above, with rocks between. 378 GRANT He waits it out until the howling tornado subsides. Then in the lull, he releases himself quickly and clambers toward the opening. He thrusts himself through the crevice, just as another breath begins. 379 EXT. ALVEOLUS CREVICE The others grab him, pull him through all the way before he can be sucked back. 380 EXT. CAPILLARY WALL - P.O.V. BUBBLE Owens is relieved to see the four start swimming back to the sub. 381 INT. CONTROL TOWER Carter is pacing in the heavy silence. Reid is watch- ing the monitors. Carter glances at the Minute Recorder. It flashes to 37. Suddenly the tapping starts. Tense, they wait for the message. It is brief. As the Wireless Operator tears it off the pad, Carter takes it. CARTER (reading) 'Proteus reports putting in to refuel air. Proceeding through the Pleural Cavity.' (suddenly realizing) Refuel air? As Reid starts to remove the OVERLAY MAP OF THE HEART from the Radarscope: REID Why not? They had a choice of over a billion Alveoli... 382 LONG SHOT - PROTEUS IN PLEURAL CAVITY The lone voyager is proceeding in a calm sea. Its headbeams reflect a yellowish cast, which becomes increasingly warm and sunny during the scene. 383 INT. BUBBLE Owens glances at the Repeater. The co-ordinates show the sub is traveling toward the apex of the Pleura, to the north, which is bounded by an undefined area simply marked "Lymphatic." A sense of absolute serenity seems to pervade. Abruptly: 384 SMASHED LASER TRANSISTOR as it is placed on the edge of an array of disassembled parts. 385 INT. LAB SECTION - WORKBENCH Cora is putting the tiny transistor down. Then, with a tweezers, she takes out the last part: a hair-like strand of wire. To Duval, who is beside her: CORA And a broken trigger-wire... 386 INT. LAB AND STORAGE SECTION Grant and Michaels are standing at the doorway, reacting to: DUVAL (fingering the parts) A smashed transistor. No way to fire the lamp... Well, that's the end of the laser. Grant and Michaels exchange looks. GRANT (to Cora) You must carry spare parts -- CORA Not anything built into the chassis. (with guilt) If it hadn't come loose -- MICHAELS That's beside the point now. (to Duval) I don't see the sense of going on. CORA We must! MICHAELS With no laser -- GRANT (to Duval) Isn't there another surgical proce- dure you can try? DUVAL No, there's no other way. Before Michaels can answer, Grant squeezes into the compartment, picks up the broken transistor. GRANT (to Cora) If you had a transistor about this size and power output, and a thin enough wire -- (of laser) -- could you piece it together? CORA No, it requires such absolute precision -- GRANT A surgeon might... CORA Oh yes, I'm sure Dr. Duval could. If we had the parts. GRANT I've got a source. All I have to do is tap it. At their blank looks, he turns and moves into: 387 INT. PROTEUS As he goes to the wireless and begins to unscrew the panel, Michaels suddenly realizes: MICHAELS Grant -- wait a minute -- you're not going to dismantle the wireless? GRANT Just one little transistor and a circuit wire is all it takes. MICHAELS But that'll knock out our communi- cations! We'll be cutting ourselves off from the outside. GRANT They'll still be able to track us by radar, because of the radio- active fuel. He moves to the panel, revealing a maze of electronic parts. GRANT Well, sir? Which is it? The wire- less, or Benes' life? MICHAELS (finally) Send the following message... A-387 OUT 388 INT. CONTROL TOWER A LUNG OVERLAY MAP is now on the Radarscope. Reid and Carter see the Grid Officer is moving the replica of the Proteus into the next quadrant of the Pleural Cavity. An incoming message is heard. The Wireless Operator takes down the message. As the tapping stops: CARTER (reading) 'Cannibalizing wireless to repair laser. This is last message.' Reid and Carter exchange grim looks. CARTER Incommunicado... Now they're really on their own. Reid moves to the window overlooking the OPERATING ROOM. As he looks down on Benes and the little Tracking Devices weaving back and forth across his chest: REID (quietly) We can still track them -- but that's all we can do. Carter joins him. As they both look down: CARTER Something told me I got into the wrong end of the business. (answering look) Inner Space... 389 OUT 390 TINY TRANSISTOR AND STRAND OF WIRE In the palm of Grant's hand. Cora's fingers delicately pick up both. CORA'S VOICE (o.s.) The transistor will do. But the wire's much too thick. 391 INT. LAB AND STORAGE SECTION Duval is picking up the original wire with the tweezers and placing it on a contrasting surface during: GRANT Nothing closer. As Cora turns to the workbench: DUVAL I may be able to scrape it thin enough. Cora, get me a number eleven scalpel. She puts the transistor and wire down on the workbench and moves to open a medical kit. Duval takes the wire and places it between two small clamps on the workbench. Cora extracts a scalpel, gives it to him. Duval swings a magnifying glass over the strand as Cora trains a light on the wire. Duval bends over. Peering through the magnifying glass, he slowly begins to scrape the strand with the scalpel. 392 GRANT AND MICHAELS They exchange looks. Then Grant turns away. 393 INT. PROTEUS Grant leads the way to the bow. As they look out: GRANT Looks like the sea, at dawn. MICHAELS We're safe -- long as it remains that color... (answering look) We're in the Pleural Sac. (indicating arched dome far above) It keeps the Lungs from rubbing against the Wall of the Chest up there. When those membranes become inflamed, we wind up with Pleurisy -- and a wracking cough. GRANT Cough? If he can kick up a storm by just breathing -- MICHAELS His Pleura's in fine condition. It should be clear sailing through this area. GRANT Let's hope... So far, somebody's tried to sabotage this mission twice. He glances back in the direction of Duval. Both drop their voices so that Duval and Cora can't hear: MICHAELS (startled) Sabotage? I don't understand... GRANT I saw the laser just before we started. It was fastened down securely. You don't suppose what happened was an 'accident?' Any more than my safety line snapping after it was tied off to the sub? MICHAELS You have no right to blame Duval -- GRANT That line was tampered with... MICHAELS (agitated) I -- I don't know what to say. I know he's under a cloud, but there's not a more dedicated man in the entire medical profession. GRANT You still never know what's going on in anyone's mind... MICHAELS (with finality) I can't believe it. Whatever happened was an accident. GRANT Two in a row? MICHAELS It's possible -- Grant looks at the Minute Recorder. It now reads 32. GRANT Thirty-two minutes left... (back to Michaels) But chances are we won't have to wait that long for try number three. OWENS' VOICE (from above) Look at those Walls up ahead! Grant and Michaels look out through the bow. Grant reacts amazed as he sees: 394 ENTRANCE OF LYMPHATIC DUCT - P.O.V. BOW A huge tube-like structure looms up. The Walls are transparent, composed of a single layer of squamous cells with round nuclei. Since the color of the stream is now predominately yellow, the globs create the impression of innumerable: GRANT'S VOICE (o.s.) Poached eggs?! 395 INT. BOW As Michaels moves to the console: MICHAELS (with smile) We're entering the Lymphatic System. Those are nuclei of cells, lining a Duct. GRANT (puzzled) I always had an idea there was only one System. The Circulatory. MICHAELS The Lymphatic System drains off excess fluid from the Tissues. Without it, we'd all swell up like balloons. He reaches the console, begins to take out a new chart. 396 INT. BUBBLE The new chart suddenly becomes visible on the Repeater as it is spread out below. Owens reacts to the labyrinth. OWENS Looks like quite a Navigation problem... The co-ordinates are seen being moved to indicate the sub is passing through a Lymphatic Duct on its way to the first Node, which is followed by a series of others, strung out like sausage links. MICHAELS' VOICE (from below) Only until we get through the Nodes -- the Lymphatic Glands. Follow your present compass heading. 397 EXT. PROTEUS - LYMPHATIC DUCT As it courses easily through the sunny stream, to suddenly emerge into: 398 EXT. LYMPHATIC NODE A startlingly different world. The headbeams reveal what appears to be an underwater marshland: a tangle of reticular fibers which wave with the gentle cross currents seeping through the mesh. Weird bacterial forms drift by, moving in groups like raiding parties. The yellowish light of the Lymphatic Stream still filters through. 399 INT. BUBBLE Owens is forced to slow down as he carefully begins to thread his way through the tangle, trying not to brush against the tendrils. But for all of Owens' care, the nose of the sub breaks some fibers as it nudges through the increasingly narrow spaces of the brambly mesh. 400 INT. PROTEUS Grant reacts as he sees the broken fibers drift against the bow windows, and then become momentarily entangled around them. When the tendrils clear the windows, he looks back to the stern. 401 FLOATING TENDRILS - P.O.V. GRANT They are floating aft. Some adhere to the propulsion section, trailing out so that Grant can see them. 402 INT. PROTEUS Grant reacts, looks back and up toward Bubble. GRANT Skipper, you're picking up seaweed -- or whatever it is. MICHAELS (reassuringly; at chart) Reticular fibers. We ought to be clear of them soon. 403 EXT. LYMPHATIC NODE - P.O.V. BUBBLE With Owens, we see the way ahead is more tangly. As he keeps slowing down to get through safely: OWENS (anxiously) I hope so, Doctor. If that stuff clogs the vents, the engine'll overheat -- He breaks off as a big clump of fibers is torn loose, for all his skillful steering. 404 EXT. UNDERSIDE OF SUB The mass of tendrils drifts down the length of the underside. Part of the clump adheres to the ventral hatch, another section twines around the exhaust: In so doing, it snags on the brambles beneath. 405 INT. LAB AND STORAGE SECTION Scalpel poised over the wire, Duval reacts as the Proteus momentarily jars while it pulls loose. He exchanges looks with Cora, who is holding the lamp. 406 INT. PROTEUS Grant glances back toward the open door of the aft compartment, realizing the danger of trying to repair the laser now. He looks at Michaels, who is bent over the chart. GRANT Doctor -- He is interrupted by a loud WHAM against the bow windows. Startled, both look off, see: 407 EXT. LYMPHATIC NODE - BEGINNING OF BATTLE BETWEEN BACTERIA AND ANTIBODIES - P.O.V. PRINCIPALS Flashing reflected light from the headbeams, elongated crystalline structures with rod-like projections which make linkage possible, are whipping against the bow windows where they have trapped a mass of ferocious- looking large Bacteria. The smaller crystalline Anti- bodies are rapidly coupling with others that speed in to join the fray. The Bacteria fight back with their flagella, in a death struggle. 408 VIEW OF BATTLE FROM INT. BUBBLE Owens ducks involuntarily as the linking Antibodies and the Bacteria slam against the Bubble in such numbers and sizes as to make the way ahead virtually invisible. As a result, the sub tears through a clump of fibers like a scythe. 409 INT. PROTEUS Duval appears in the doorway. DUVAL What's causing all that -- ? He breaks off as he sees the Antibodies and Bacteria whipping against the windows. Cora appears behind him, gasps at the sight of the monsters locked in battle. GRANT Looks like somebody declared war. MICHAELS Just what it is. Antibodies, destroying Bacteria -- or any other foreign invader that threatens the System. 410 BIG CLOSEUP - ONE ANTIBODY AND BACTERIUM As both slam and hold against the bow windows in a life-and-death struggle. An amazing phenomenon is taking form: Antibodies are hooking up at the rods to completely encase the Bacteriu
