1: INT. WENLEY MOOR ATOMIC RESEARCH STATION. LABORATORY
(The DOCTOR sits in the laboratory making out the formula on a pad. The door to the corridor is open behind him. He hears a humming
noise and stops writing, listening intently with a frown. He continues to write as, behind him, the wall in the corridor starts to glow
an orange colour. The DOCTOR is oblivious as smoke pours from the wall and, from its billowing clouds, the YOUNG SILURIAN and SILURIAN
SCIENTIST burst through. They stride into the laboratory and immediately blast the DOCTOR with their third eyes. Staring upwards, he
sinks to the floor...)
2: INT. WENLEY MOOR ATOMIC RESEARCH STATION. CONFERENCE ROOM
(Private Upton stands before the BRIGADIER'S desk.)
BRIGADIER LETHBRIDGE STEWART: And there's no news from cave mouth two?
PRIVATE UPTON: We've lost contact with cave mouth two, sir.
BRIGADIER LETHBRIDGE STEWART: Well, I want reports from all sectors as they come in - and get me Captain Hawkins.
PRIVATE UPTON: Sir!
(He leaves as LIZ walks in. She smiles.)
LIZ: I've checked on the ambulance man in the sick bay. The discolouration of the skin is fading rapidly.
BRIGADIER LETHBRIDGE STEWART: So the Doctor's antidote seems totally effective?
LIZ: So far, yes.
(The BRIGADIER bangs the desk in frustration.)
BRIGADIER LETHBRIDGE STEWART: I wish he'd get a move on with that formula!
3: INT. WENLEY MOOR ATOMIC RESEARCH STATION. LABORATORY
(The unconscious DOCTOR is dragged backwards from the laboratory in the arms of the SILURIAN SCIENTIST.)
4: INT. WENLEY MOOR ATOMIC RESEARCH CENTRE. RECEPTION FOYER
(The YOUNG SILURIAN follows them. Private Upton walks into the reception foyer and sees what is happening in the side corridor.)
PRIVATE UPTON: (Shouts.) Sergeant!
(The YOUNG SILURIAN spins round and blasts the soldier to the ground with his third eye.)
YOUNG SILURIAN: Quickly! There may be others.
(Leaving the body of the soldier behind, the SCIENTIST drags the DOCTOR into the recently created hole in the wall. The YOUNG SILURIAN
follows, turns and fires its third eye at the gap. There is the humming sound again, along with the smoke and the tunnel is sealed.
Smoke drifts across the area as NUTTING'S corpse lies unattended...)
5: INT. WENLEY MOOR ATOMIC RESEARCH STATION. CONFERENCE ROOM
(LIZ holds one phone call while the BRIGADIER speaks into a UNIT R/T phone at the back of the room.)
BRIGADIER LETHBRIDGE STEWART: (Into phone.) Hold them long as you can. I'm doing my level best to get you the support
(A third phone rings and LIZ picks it up.)
LIZ: (Into phone.) UNIT control?
BRIGADIER LETHBRIDGE STEWART: (Into phone.) Over and out.
LIZ: (Into phone.) Yes, Doctor...Crawford.
BRIGADIER LETHBRIDGE STEWART: (To A UNIT soldier.) Wilcox, bring them down here.
(The BRIGADIER rushes to his desk and takes the second phone from LIZ.)
LIZ: (Into phone.) I...I know. Look, I'm terribly sorry.
BRIGADIER LETHBRIDGE STEWART: (Into phone.) Look, what's happening about my call to the Ministry of Defence?
LIZ: (Into phone.) I'm sure the Doctor won't be much longer.
BRIGADIER LETHBRIDGE STEWART: (Into phone.) Well, look, hurry it up, man - this is top priority!
(He puts his phone down...)
LIZ: (Into phone.) Yeah, I do realise, all right. Goodbye.
(...as does LIZ.)
BRIGADIER LETHBRIDGE STEWART: Trouble?
LIZ: Dr. Meredith is getting very impatient.
BRIGADIER LETHBRIDGE STEWART: I can't say I blame him.
LIZ: Give the Doctor a couple more moments. I...I mean he may have run into some kind of problem.
6: INT. WENLEY MOOR ATOMIC RESEARCH CENTRE. RECEPTION FOYER
(The lift from the surface finishes its descent and the door opens. CAPTAIN HAWKINS walks out and immediately sees the body of Private
Upton on the floor. He unholsters his pistol and looks warily round. Seeing no one, he checks NUTTING, looks up and sees an arch-shaped
scorch mark on the corridor wall where the tunnel was sealed up. He walks over to examine it. At that moment, a white suited technician
walks into the foyer and stops dead when he sees the corpse.)
CAPTAIN HAWKINS: Here you! Give me a hand.
(The technician hesitates.)
CAPTAIN HAWKINS: Well don't stand there gawping, man! Come on, give me a hand!
(The technician overcomes his shock and helps HAWKINS with the body.)
7: INT. WENLEY MOOR ATOMIC RESEARCH STATION. CONFERENCE ROOM
(The BRIGADIER is on the phone again.)
BRIGADIER LETHBRIDGE STEWART: (Into phone.) Yes, all right, Major Walton. Pull back from gallery four...
(A second phone rings...)
BRIGADIER LETHBRIDGE STEWART: (Into phone.) ...and try and hold them at cave mouth three.
(...and LIZ answers it.)
LIZ: (Into phone.) UNIT control?
BRIGADIER LETHBRIDGE STEWART: (Into phone.) Over and out.
(The BRIGADIER puts his phone down.)
LIZ: (Into phone.) Oh, yes sir. He's here - hold the line.
(She hands him the second phone.)
LIZ: The Ministry of Defence.
(He takes it but speaks urgently to LIZ.)
BRIGADIER LETHBRIDGE STEWART: Miss Shaw, I must have that formula.
LIZ: All right, I'll go and see what's holding the Doctor up.
(She gets up and runs out as the BRIGADIER speaks to his caller.)
BRIGADIER LETHBRIDGE STEWART: (Into phone.) Lethbridge Stewart here, sir. You got my message? (He listens.)
With respect, sir, I don't think you appreciate the gravity of the situation. (Listens.) But there's no time to refer it to the
8: INT. WENLEY MOOR ATOMIC RESEARCH STATION. LABORATORY
(LIZ runs into the laboratory, casting a surprised glance at the scorch mark on the opposite wall in the corridor.)
LIZ: Doctor, the Brig...
(She sees that the laboratory is empty. She steps forward and onto a smashed test tube on the floor. She picks up the glass in puzzlement
together with a screwed up piece of paper. She also picks that up and then looks over the bench. There is an untidy mass of papers there.
She grabs them, thinks for a moment and then rushes from the room with the papers in her hand.)
9: INT. WENLEY MOOR ATOMIC RESEARCH STATION. CONFERENCE ROOM
(Having returned to the Conference Room, she has told the BRIGADIER, holding yet another phone call, of what she has found.)
BRIGADIER LETHBRIDGE STEWART: But where is he?!
LIZ: I've told you - I've no idea.
BRIGADIER LETHBRIDGE STEWART: You'll read the formula to Dr. Crawford - he's been hanging on long enough.
LIZ: Don't you understand? I don't know which is the formula.
(The BRIGADIER sighs and returns to his phone call.)
BRIGADIER LETHBRIDGE STEWART: (Into phone.) Hello, Dr. Crawford? Look, I'm afraid I'll have to ring you back. There's
been yet another delay. (He listens.) Yes, yes, yes, as soon as I can.
(He puts the phone down. LIZ frowns.)
LIZ: Brigadier, there was some glass in the lab. I...I don't know if there's...
(The doors to the room burst open and CAPTAIN HAWKINS runs in.)
CAPTAIN HAWKINS: Sir! Sir, there's been some kind of a raid. Private Upton's dead.
BRIGADIER LETHBRIDGE STEWART: In the caves?
CAPTAIN HAWKINS: No, sir - here. Just down the corridor - and there's a kind of scorch mark on the wall.
(The BRIGADIER looks stupefied for a moment. Then he jumps up and grabs his gun belt as LIZ starts to search through the papers she
has brought with her from the laboratory.)
BRIGADIER LETHBRIDGE STEWART: Stay here, Miss Shaw.
BRIGADIER LETHBRIDGE STEWART: Stay here!
LIZ: Yes, of course!
(The BRIGADIER runs out, closely followed by CAPTAIN HAWKINS. LIZ continues to read through the papers. She stops on one, glances
at the rest, unscrews the paper that she picked up from the floor of the laboratory. Reading it, she smiles and then picks up one of
LIZ: (Into phone.) Get me Dr. Crawford, please.
10: INT. SILURIAN BASE. LABORATORY
(The DOCTOR, still in his white lab coat, has been placed back inside the cage in the SILURIAN laboratory. He looks through the horizontal
bars at his captors.)
SILURIAN SCIENTIST: How many humans have survived the epidemic?
DOCTOR: They will all survive.
YOUNG SILURIAN: That is impossible!
SILURIAN SCIENTIST: You have discovered a cure?
DOCTOR: Yes, and soon all the humans will be immune to your epidemic. Your plan has failed, as your leader wanted it to fail.
YOUNG SILURIAN: Our leader is dead - I killed him. I am the leader now.
(The DOCTOR looks stunned at this development...)
11: INT. WENLEY MOOR ATOMIC RESEARCH STATION. CONFERENCE ROOM
(This time it is LIZ who is on the phone...)
LIZ: (Into phone.) Thank you, Dr. Crawford.
(She puts the phone down as the BRIGADIER walks in with CAPTAIN HAWKINS.)
BRIGADIER LETHBRIDGE STEWART: (To LIZ.) The Silurians have broken in.
LIZ: Well, what about the Doctor?
BRIGADIER LETHBRIDGE STEWART: Well, I imagine they've taken him to their base. Captain Hawkins, send every man we've got into
the caves, and I want all civilian personnel evacuated from here immediately.
CAPTAIN HAWKINS: Sir.
BRIGADIER LETHBRIDGE STEWART: And organise a thorough search of that laboratory.
CAPTAIN HAWKINS: I'll see to it myself, sir.
(He shouts to the two UNIT soldiers in the room.)
CAPTAIN HAWKINS: You two - come with me.
LIZ: I've given the formula to Dr. Crawford. They're going to make their own tests and then go into mass production of the
BRIGADIER LETHBRIDGE STEWART: Well done, Miss Shaw.
LIZ: What are you going to do about the Doctor?
BRIGADIER LETHBRIDGE STEWART: (Sadly.) What can I do?
LIZ: Try to rescue him! You'll have to attack their base.
BRIGADIER LETHBRIDGE STEWART: At the moment, they seem to be attacking us.
12: INT. CAVES
(A full scale battle is in order in the caves. A UNIT soldier blasts away at his attackers.)
13: INT. SILURIAN BASE. LABORATORY
(The sound of the gunfire reaches the base. As the DOCTOR listens, the YOUNG SILURIAN and the SCIENTIST confer...)
YOUNG SILURIAN: Since the epidemic has failed, we must use other means. We intend to make this planet uninhabitable for humans
DOCTOR: But you can't do that! You can exterminate a whole species!
YOUNG SILURIAN: (To the SCIENTIST.) Is the disperser ready for activation?
SILURIAN SCIENTIST: All we need now is the power.
YOUNG SILURIAN: We shall continue to use the electricity of the humans.
DOCTOR: I think you won't be able to do that. Thanks to you, the humans are no longer making power. Their generator has been
SILURIAN SCIENTIST: Then you will help us.
YOUNG SILURIAN: We shall force you to reactivate it. We shall take the centre!
14: INT. WENLEY MOOR ATOMIC RESEARCH STATION. CONFERENCE ROOM
(The BRIGADIER, sat at his table, taps the phone cradle.)
BRIGADIER LETHBRIDGE STEWART: (Into phone.) Hello?
(There is no response.)
BRIGADIER LETHBRIDGE STEWART: (Into phone.) Hello? Hello? Switchboard? (To LIZ.) What's the matter with this
(Suddenly, the lights in the room dim and the hum of the air conditioning dies down.)
BRIGADIER LETHBRIDGE STEWART: What the devil...?
LIZ: We seem to have switched to an emergency lighting system.
(LIZ picks up another phone.)
LIZ: (Into phone.) Hello? (To the BRIGADIER.) It's dead.
(The BRIGADIER picks up the R/T phone which has now been placed on his desk. LIZ winds up the call handle. Not receiving any response,
she winds it up again.)
BRIGADIER LETHBRIDGE STEWART: This one's dead too. And I've just sent the last of my men into those caves.
LIZ: What do you mean?
BRIGADIER LETHBRIDGE STEWART: Because of the attack, I sent every man I've got down to the caves and now the Silurians are
cutting our communications.
LIZ: What about your pocket radio?
BRIGADIER LETHBRIDGE STEWART: No, useless at this depth.
LIZ: If they could break in once to get the Doctor...they could break in again.
BRIGADIER LETHBRIDGE STEWART: Exactly.
(He stands up.)
BRIGADIER LETHBRIDGE STEWART: Only this time it'll be in force.
15: INT. SILURIAN BASE. REVIVIFICATION AREA
(The SILURIAN SCIENTIST is in the revivification area. He stands over one of the large caskets and uses his third eye to try and
resuscitate one of the individuals contained within. There is no response. The large hatchway rises into the ceiling and the YOUNG SILURIAN
YOUNG SILURIAN: Is the machinery prepared?
SILURIAN SCIENTIST: I could do nothing without power from the human's generator. It has ceased to function.
YOUNG SILURIAN: We shall force them to reactivate it. When your instruments register the power, you will revive all
our people. Now, I shall take the one called “the Doctor” to the research centre.
(He turns and walks out as the SCIENTIST starts to examine the machinery.)
16: INT. WENLEY MOOR ATOMIC RESEARCH CENTRE. RECEPTION FOYER
(As a soldier crosses the foyer, the BRIGADIER and LIZ enter.)
BRIGADIER LETHBRIDGE STEWART: I'll go to the Ministry myself. We need a division down here and I'll see we get it.
(He crosses to the lift and presses the button. There is no response.)
BRIGADIER LETHBRIDGE STEWART: What's the matter with this thing?
LIZ: The telephone's stopped working.
BRIGADIER LETHBRIDGE STEWART: Now the lift as well.
(Suddenly, the scorch-marked wall begins to glow.)
LIZ: Brigadier - look!
(LIZ and the BRIGADIER glance at each other in astonishment and then look back at the wall that begins to smoke and open, revealing
the reptile-made passage beyond. A familiar white-coated figure walks out and through the smoke.)
(The DOCTOR stops. Behind him, the SILURIANS start to emerge. The BRIGADIER reaches for his pistol.)
YOUNG SILURIAN: Put down that weapon!
17: INT. WENLEY MOOR ATOMIC RESEARCH STATION. LABORATORY
(Across the corridor, in the darkened laboratory, CAPTAIN HAWKINS hears the exchange and moves behind the open door, drawing his
pistol as he goes.)
DOCTOR: Do as he says, Brigadier...or they'll kill us all.
18: INT. WENLEY MOOR ATOMIC RESEARCH CENTRE. RECEPTION FOYER
(The BRIGADIER reluctantly drops his own gun.)
SILURIAN SCIENTIST: We do not need these humans.
DOCTOR: Miss Shaw is a scientist. If I am to do what you want, I shall need her help.
YOUNG SILURIAN: The other one is a soldier - he is dangerous. Kill him!
(A SILURIAN steps forward and activates its third eye. At the same time, CAPTAIN HAWKINS comes out of the laboratory and starts firing
his pistol at the group of reptiles. The SILURIAN turns its aim at HAWKINS as the DOCTOR struggles in another SILURIAN'S grasp.)
DOCTOR: (Shouts.) Stop!
LIZ: (Shouts.) Brigadier!
DOCTOR: (Shouts.) Stop!
(HAWKINS falls to the ground and the SILURIAN stops firing.)
DOCTOR: (Shouts.) There'll be no more killing or I shall refuse to help you! You'll have to kill me too!
YOUNG SILURIAN: You will take us to the nuclear generator - or we will kill you all!
(The DOCTOR considers, then thrusts off the holding SILURIAN'S arm.)
DOCTOR: Very well. I'll do as you want.
(He is pushed across the foyer towards the Cyclotron Room.)
19: INT. WENLEY MOOR ATOMIC RESEARCH CENTRE. CYCLOTRON ROOM
(There, the remaining technicians work peacefully in the semi-darkened room. Suddenly, a pair of double doors in the lower level
burst open and the two lead SILURIANS enter. The amazed and frightened technicians scramble to the back of the room. Despite the DOCTOR'S
injunction, the two SILURIANS immediately start firing at the helpless humans. The women in the room scream as two technicians fall
to the ground. The DOCTOR runs in behind the two SILURIANS...)
DOCTOR: (Shouts.) Stop! Stop!
(...and pulls them away from firing again.)
DOCTOR: I said there was to be no more killing!
(The technicians make a break en masse for the upper level and the other door.)
DOCTOR: (Shouts.) Right, stay where you are!
(They all stop and listen.)
DOCTOR: This centre is now in the hands of the Silurians. They need the use of the generator. Now if you follow carefully
the instructions I shall give you, your lives may be spared.
YOUNG SILURIAN: Remove the bodies.
(As the SILURIANS move away from the DOCTOR, the BRIGADIER sidles up to him.)
BRIGADIER LETHBRIDGE STEWART: Doctor, what do you think you're doing?
DOCTOR: (Urgently.) Trying to save your lives. Now keep out of the way and keep quiet.
(The SILURIAN SCIENTIST moves forward.)
SILURIAN SCIENTIST: You will now connect this device to the nuclear generator.
(He points back through the double doors.)
DOCTOR: The power source is over here.
(The DOCTOR points across the room and leads the SCIENTIST to the drum of the cyclotron. Behind them, two SILURIANS wheel their device
into the room. It resembles a stubby cannon with a radar-type dish and prong atop it.)
DOCTOR: What is the purpose of this machine?
YOUNG SILURIAN: That is no concern of yours.
DOCTOR: If I'm to help you, I must know.
(The YOUNG SILURIAN nods his permission to the SCIENTIST to reveal the purpose of the device.)
SILURIAN SCIENTIST: This...is the molecular disperser. It will convert the energy of the nuclear reactor into microwaves.
DOCTOR: Oh, for what purpose?
SILURIAN SCIENTIST: The microwaves will disperse the molecules of the filter belt which has enveloped this planet since our
(LIZ, listening carefully to this explanation, frowns in concern.)
DOCTOR: But if this process gets out of hand, it will destroy all life on the planet?
SILURIAN SCIENTIST: We can control the process. Commence work!
(With reluctance, the DOCTOR picks up a cable from the cyclotron and moves towards the SILURIAN device.)
BRIGADIER LETHBRIDGE STEWART: (To LIZ, quietly.) What are they gonna do?
LIZ: (Quietly.) Destroy the Van Allen belt.
BRIGADIER LETHBRIDGE STEWART: (Quietly.) What?
LIZ: (Quietly.) The Van Allen belt. It surrounds the planet and filters out some of the sun's radiation.
BRIGADIER LETHBRIDGE STEWART: (Quietly.) What happens when it's gone?
LIZ: (Quietly.) It gets so hot, we will all die of sunburn on a cloudy day.
BRIGADIER LETHBRIDGE STEWART: (Quietly.) What good will that do them?
LIZ: (Quietly.) They're reptile - cold blooded. They'll thrive in heat - we shall die. It'll mean the end of the human
(The DOCTOR continues his work...)
20: INT. SILURIAN BASE. REVIVIFICATION AREA
(Back in the SILURIAN base, three of the reptiles look over one of the resuscitation coffin-like units. The door hatchway opens and
a fourth SILURIAN walks in.)
SILURIAN: The generator of the humans is producing power. Commence the revival process.
(This newly arrived SILURIAN and another turn their third eyes on the unit. After a moment, the lid rises upwards as within an awakening
SILURIAN pushes it upwards. The revived reptile suddenly shudders in spasms, groans and falls back. The lid of the unit also falls back
SILURIAN: The power is still too low.
21: INT. WENLEY MOOR ATOMIC RESEARCH CENTRE. CYCLOTRON ROOM
(The DOCTOR has stripped off his lab coat to engineer the link between the cyclotron and the SILURIAN device. In a white T-shirt
and trousers, he awaits further instructions from the SILURIAN SCIENTIST as he inspects the DOCTOR'S work.)
SILURIAN SCIENTIST: You will now provide power to operate the re-hibernation machinery and activate the disperser.
DOCTOR: Yes, well, we'll...need to stoke up the reactor. (To LIZ.) Miss Shaw, I'll need your help, please.
(He moves towards the upper level control room as the BRIGADIER whispers urgently to LIZ.)
BRIGADIER LETHBRIDGE STEWART: You mustn't help him!
LIZ: The Doctor knows what he's doing - trust him.
(LIZ also goes into the upper level. The DOCTOR is sat at the control desk with the YOUNG SILURIAN hovering over him.)
DOCTOR: Miss Shaw, I want you to feed uranium into the reactor – all right?
(LIZ nods and the YOUNG SILURIAN moves off. The DOCTOR uses the chance.)
DOCTOR: (Quietly.) When I tell you, lower all the rods in at once.
LIZ: (Shocked.) Doctor, ___!
DOCTOR: (Interrupts.) Liz, I know what I'm doing. Please do as I say.
(LIZ moves back down to the lower level and sits at the control desk there.)
DOCTOR: (Into microphone.) Er, all technicians to your usual sectors, please. To your usual sectors, please.
(The DOCTOR watches as the technicians move reluctantly back to their posts.)
DOCTOR: (Into microphone.) Alright, Liz?
LIZ: (Into microphone.) Yes.
DOCTOR: (Into microphone.) Er, lower in number one rod.
(There is a hum as LIZ carries out the instruction.)
LIZ: (Into microphone.) Number one rod - check.
(The whirr of increased power starts to build up.)
DOCTOR: (Into microphone.) Lower in number two rod.
(There is another hum, then...)
LIZ: (Into microphone.) Number two rod - check.
(The power of the cyclotron builds up further and its drum glows brighter. The SILURIAN SCIENTIST and another of the reptiles check
over the disperser.)
DOCTOR: (Into microphone.) Er, sector one, increase your power level. Lower in number three rod.
(Again a hum and the increase of power as the BRIGADIER watches on disapprovingly.)
LIZ: (Into microphone.) Number three rod - check.
DOCTOR: (Into microphone.) Now you should be getting enough power now to get your disperser unit into operation.
(The SCIENTIST looks over the machine. The probe on top of it starts to glow with a series of alternating lights. The impatient YOUNG
SILURIAN steps forward to the DOCTOR.)
YOUNG SILURIAN: Continue to increase the power.
DOCTOR: Very well. (Into microphone.) Liz... (Shouts.) Now!
(LIZ urgently turns several dials. The whirr of power in the room starts to run away and a huge explosion suddenly rends the SILURIAN
disperser. At the same time, the alarms in the room start to blare out and the technicians run in a panic at the oncoming nuclear overload.)
YOUNG SILURIAN: (To the DOCTOR.) You have ___ ___the disperser!
DOCTOR: Yes, I know.
(The YOUNG SILURIAN runs down into the lower room.)
YOUNG SILURIAN: (To LIZ.) Turn off the reactor!
SILURIAN SCIENTIST: (To LIZ.) Remove the uranium from the reactor.
(LIZ gets up and moves across slowly to a panel. The SILURIAN SCIENTIST roughly pushes her towards it faster.)
DOCTOR: (Into microphone.) Liz, keep away from those controls - get back!
(LIZ steps back as the control panel itself explodes. She runs back to her control desk as the SILURIANS hover over her, uncertain
what to do next. The DOCTOR loudly but calmly shouts through the intercom system over the noise of the reactor and the alarm.)
DOCTOR: (Into microphone.) The reactor is now permanently overloaded. There's going to be a massive explosion, and
a colossal radiation leakage.
BRIGADIER LETHBRIDGE STEWART: (To the SILURIANS.) The whole area will become deadly.
YOUNG SILURIAN: For how long?
LIZ: A quarter of a century - possibly more.
SILURIAN SCIENTIST: (To the YOUNG SILURIAN.) This means nothing to us. We shall return to our base and wait in hibernation
until the radiation has faded. Kill these humans!
YOUNG SILURIAN: No! They will all stay here to die...from the radiation.
(There is an anxious moment as the SILURIANS hover over the lower control desk and LIZ. Then, slowly they start to back out of the
room. As soon as they have gone, the BRIGADIER runs to the upper level where the DOCTOR is sat with his chin in his hands. LIZ joins
BRIGADIER LETHBRIDGE STEWART: (Warmly.) Well done, Doctor.
DOCTOR: Well done, Brigadier.
BRIGADIER LETHBRIDGE STEWART: Well hadn't you better close down the reactor?
DOCTOR: I can't.
(The smiles disappear from the faces of the BRIGADIER and LIZ.)
BRIGADIER LETHBRIDGE STEWART: You were surely bluffing?
DOCTOR: Well, I exaggerated a bit...but I had to push the reactor past the critical stage or they'd never have believed me.
We'd better get out of here at once.
(The DOCTOR stands.)
BRIGADIER LETHBRIDGE STEWART: We can't.
DOCTOR: Why not?
BRIGADIER LETHBRIDGE STEWART: They've jammed the lift - there's no way out.
(The DOCTOR looks at him in stunned silence.)
22: INT. SILURIAN BASE. REVIVIFICATION AREA
(The reptiles have made it back to their base. The SILURIAN SCIENTIST stands over one of the revivification units, training his third
eye on it. The unit glides across the room and under an overhanging panel. The wall hatch slides upwards and the YOUNG SILURIAN enters.)
SILURIAN SCIENTIST: The re-hibernation mechanism is defective. One of us must remain.
YOUNG SILURIAN: I am the leader - the responsibility is mine.
SILURIAN SCIENTIST: The one who remains here will die.
YOUNG SILURIAN: Is sufficient power stored in the hibernation unit?
SILURIAN SCIENTIST: Yes, I have set the controls to revive us in fifty years from now.
YOUNG SILURIAN: When our people revive, you will be the leader. See that the apes are destroyed.
23: INT. WENLEY MOOR ATOMIC RESEARCH CENTRE. CYCLOTRON ROOM
(The alarm continues to blare across the cyclotron room and two meters showing the wattage are still at a critical level. The DOCTOR
lies face upwards under the upper level control desk, manipulating the wires underneath. LIZ looks at the dials and meters on the desk.)
BRIGADIER LETHBRIDGE STEWART: Any good now?
LIZ: No, it's still not working.
DOCTOR: (Calmly.) Give me time, Liz, give me time.
(He cross-wires more of the machinery and plugs them together.)
DOCTOR: There we are - try that now.
LIZ: The mega-wattage is still rising.
(The DOCTOR gets up and looks over the controls, thinking furiously. Suddenly, he snaps his fingers.)
DOCTOR: Yes, I know. I'll try fusing the control of the neutron flow. Now stand well back and cover your eyes.
(The BRIGADIER and LIZ move to the back of the room and face the wall with their arms up in protection. The DOCTOR presses several
controls and joins them. There is a tremendous explosion from within the control desk and, simultaneously, the whirr of the reactor
decreases and the alarm ceases.)
DOCTOR: Ha ha! Well, that seems to have done it.
24: INT. SILURIAN BASE. LABORATORY
(The DOCTOR is back in his pot-holing gear and has re-entered the SILURIAN base. He cautiously enters the silent and deserted laboratory.
He makes his way through it...)
25: INT. SILURIAN BASE. REVIVIFICATION AREA
(...and into the equally silent and seemingly deserted revivification area. He starts to look over the machinery with interest when
he hears a voice behind him.)
YOUNG SILURIAN: You are still alive?
(The YOUNG SILURIAN enters the area from the laboratory.)
YOUNG SILURIAN: You tricked us!
DOCTOR: I managed to close down the reactor.
YOUNG SILURIAN: Then the others must be revived at once. But first, I shall kill you!
(The YOUNG SILURIAN starts firing his third eye.)
26: INT. SILURIAN BASE. LABORATORY
(At the same time, the BRIGADIER who has surreptitiously followed the DOCTOR down to the base, runs forward...)
BRIGADIER LETHBRIDGE STEWART: Doctor!
(...and starts firing his pistol through the open doorway at the YOUNG SILURIAN...)
27: INT. SILURIAN BASE. REVIVIFICATION AREA
(...who staggers under the impact. The DOCTOR runs for cover behind the machinery...)
28: INT. SILURIAN BASE. LABORATORY
(...as the BRIGADIER fires bullet after bullet.)
29: INT. SILURIAN BASE. REVIVIFICATION AREA
(The YOUNG SILURIAN'S cries turn to groans as it sinks to the ground and then lies still. The DOCTOR comes out of hiding as the BRIGADIER
walks forward, holstering his gun.)
DOCTOR: Well done, Brigadier. Now then...
(He turns back to the machinery.)
BRIGADIER LETHBRIDGE STEWART: And just what do you think you're doing down here?
DOCTOR: I'm trying to find out how this hibernation unit works. I must know if we're gonna revive them again.
BRIGADIER LETHBRIDGE STEWART: (Amazed.) Revive them?!
DOCTOR: Yes, not all at once you understand. Er, one at a time, so that we can reason with them. There's a wealth of scientific
knowledge down here, Brigadier, and I can't wait to get started on it.
(He continues to look over the machinery as the BRIGADIER looks down at him through narrowed eyes.)
30: INT. WENLEY MOOR ATOMIC RESEARCH CENTRE. CYCLOTRON ROOM
(The Cyclotron Room seems to have undergone its repairs and is back to normal with all the technicians back at their posts. The DOCTOR
is back in his normal clothes – including cloak – and he steps up into the upper level control room. LIZ, with her coat on, follows
him. The BRIGADIER waits in the control room along with CORPORAL NUTTING and another UNIT soldier.)
DOCTOR: Yes, well everything seems to be working quite smoothly. I don't think they'll be any more trouble.
BRIGADIER LETHBRIDGE STEWART: Splendid.
DOCTOR: Now don't forget, Brigadier, nobody is to go into that Silurian base.
BRIGADIER LETHBRIDGE STEWART: Yes, Doctor.
DOCTOR: Miss Shaw and I will be back as soon as possible with some testing equipment and probably some other scientists.
BRIGADIER LETHBRIDGE STEWART: (Hastily.) Good, good, well, have a good journey.
(The DOCTOR looks at him with some suspicion.)
DOCTOR: Yes... Don't forget, Brigadier - nobody is to go into that base - all right?
DOCTOR: I'll see you tomorrow.
BRIGADIER LETHBRIDGE STEWART: Goodbye, Miss Shaw.
(They head for the door which the UNIT soldier holds open for LIZ.)
LIZ: Thank you.
(After they have gone, there is a moment's silence.)
BRIGADIER LETHBRIDGE STEWART: Corporal Nutting?
CORPORAL NUTTING: Sir?
(The CORPORAL steps forward.)
BRIGADIER LETHBRIDGE STEWART: Everything set up?
CORPORAL NUTTING: Yes, sir.
BRIGADIER LETHBRIDGE STEWART: Give them time to get clear, and then set off those explosive charges. I want that Silurian
base sealed permanently.
31: INT. SILURIAN BASE. REVIVIFICATION AREA
(Within the base, the YOUNG SILURIAN is not dead. It breathes heavily and stirs on the floor. Weakly, it crawls across to a resuscitation
unit and, grasping to the unit for support, heaves itself to its feet. It fires its third eye at the unit but its own power is weak.)
32: EXT. WENLEY MOOR
(The DOCTOR'S new car has broken down. At an isolated spot on the lonely moor, he stands with the detachable bonnet in his hands
and ponders the cause as LIZ looks on somewhat sardonically from the passenger seat.)
LIZ: Shall I walk back and get some help?
DOCTOR: No, no. No, it's just a minor technical fault. We'll soon put that right.
(He puts the bonnet back into place and unscrews the radiator cap. Whistling, he reaches into his pocket and pulls out a stoppered
test tube containing a green liquid. He takes the top off and pours the liquid into the open cap. Smoke starts to come out. He puts
the cap back on, checks his watch and listens as a bubbling noise comes from the car. Still checking the timings on his watch, he walks
slowly down the length of the car, tracing out the progress of the liquid, up down and along with his right finger against where it
should be within the machinery of the vehicle. LIZ watches with interest. He reaches the back of the car and, right on cue, the liquid
comes out of the exhaust pipe and the car starts up.)
DOCTOR: There you are - that's fixed it.
(LIZ smiles as the DOCTOR returns to his seat. The peace of the moor is suddenly shattered by a huge explosion.)
LIZ: What's that?
(She looks across the moorland as a massive fireball erupts from a cave mouth.)
33: INT. SILURIAN BASE. REVIVIFICATION AREA
(Inside the base, the YOUNG SILURIAN screams out as the explosions tear into the infrastructure. It falls to the ground as smoke
and flame fill the base.)
34: EXT. WENLEY MOOR
(More explosions pour out of the cave mouth. The DOCTOR looks horrified.)
DOCTOR: The Brigadier - he's blown up the Silurian base.
LIZ: He must have had orders from the Ministry.
(The DOCTOR looks at her.)
DOCTOR: And you knew?
LIZ: (Sharply.) No! The government were frightened. They just couldn't take the risk.
DOCTOR: But that's murder. They were an intelligent alien beings. A whole race of them. He's just wiped them out.
(There is another explosion.)
LIZ: (Sadly.) I know.
(The DOCTOR puts the car into gear. Another explosion tears across the moorland and the DOCTOR looks up with anger on his face. In
silence, he moves the car off as the fireball from the explosion rises into the moorland sky...)
