1: EXT. THE LAKE OF MUTATIONS
(The water begins to bubble and seethe. When ELYON turns back round, the water has been whipped into a large whirlpool. He turns to run but something has
grabbed his legs. He screams…)
2: EXT. SWAMP
(His scream carries to the camp. The party jumps up…)
GANATUS: Stay here!
(He and IAN run to the lake leaving BARBARA and the other Thals behind, wondering what awaits their companions at the lakeside…)
3: EXT. THE LAKE OF MUTATIONS
(One water-bag remains on the bank...)
(...and this is discovered when IAN and GANATUS arrive at the lakeside. Despite GANATUS’S previous order, BARBARA and KRISTAS arrive at the scene. They all
see the remains of the other water-bags drifting on the lake itself in the last slow swirls of the whirlpool from which small bubbles of air erupt to the
surface. The four stand in silence as a horrified ANTODUS runs up.)
ANTODUS: What is it? What’s happened to Elyon?
(He sees what remains. All stare at the water for a moment.)
IAN: There’s nothing we can do here.
(IAN leads her away from the lake, KRISTAS following. A shaking ANTODUS is left behind with GANATUS.)
ANTODUS: Did...Elyon...fall in?
(He falls to his knees, barely holding himself together.)
ANTODUS: What happened?
(GANATUS bends down to comfort him.)
GANATUS: It must have happened very quickly. Come on now, we must reach the cliffs by tonight.
(He leads his brother away from the scene.)
4: EXT. FOREST EDGE
(From behind the cover of a tree, SUSAN observes the city through the DOCTOR’S long handled binoculars. After a moment, she crosses to where the DOCTOR,
ALYDON and DYONI are hunched behind a boulder. A map of the city rests on top of the boulder. SUSAN hands ALYDON the glasses and then describes her observations
pointing at the map.)
SUSAN: There are four roads that lead off from the main square, going north, south, east and west.
(DYONI draws in the features that SUSAN describes. ALYDON lowers the glasses and points to one area on the map.)
ALYDON: The main ventilators seem to be over in this section.
SUSAN: (Points.) Oh, that’s right. It goes down there and up.
DOCTOR: (To ALYDON.) Can you see any way in at all?
DOCTOR: Oh, well, allow me, will you?
(ALYDON passes the glasses to the DOCTOR who stands up from behind the boulder to observe.)
SUSAN: Grandfather, get down!
(She pulls him back down.)
DOCTOR: Yes, yes, yes. Now the...the things we have to put out of action is the radio and television waves. They’ve obviously got complete coverage
in and around the city.
ALYDON: They don’t leave much to chance.
DOCTOR: We must presume they don’t leave anything to chance.
DYONI: If they have pictures of the entrance to the city, how can we do anything?
DOCTOR: Then we must stop the pictures. Remember, the Daleks aren’t very mobile.
SUSAN: Yes, we do have speed on our side.
DOCTOR: And there’s always value in surprise. I know it looks difficult, but…we must try it, my friends! Yes, we must!
ALYDON: (Pensively.) Yes. I wish I knew what they were planning for us.
5: EXT. CITY
(In the city…)
6: INT. CITY. CONTROL ROOM
(…a DALEK glides towards a control panel where another DALEK reports.)
FIRST DALEK: The report on the neutron bomb is prepared.
SECOND DALEK: Let us hear it.
(The FIRST DALEK turns to the control panel and activates a switch. Pulsing patterns appear on the screen.)
DALEK: (OOV: Over intercom.) Report on Neutron bomb: to cover five hundred square miles, time to construct - twenty three days.
FIRST DALEK: Is that the shortest possible time?
DALEK: (OOV: Over intercom.) Yes.
FIRST DALEK: Very well.
(It switches off the intercom.)
FIRST DALEK: It is too long.
SECOND DALEK: We must abandon the idea of a neutron bomb.
FIRST DALEK: We must find another way of spreading radiation.
6: INT. CAVE TUNNEL
(Holding a light, GANATUS leads BARBARA down a treacherous and dark tunnel. She stumbles slightly and GANATUS steadies her.)
GANATUS: It’s getting narrower.
BARBARA: Oh, it’s like all the other caves - just tails off into a dead end.
GANATUS: (Smiles.) Now there’s a gloomy thought for you!
(They laugh gently and continue onwards.)
BARBARA: I wonder if Ian’s doing any better?
GANATUS: When did we arrange to...meet him and the others?
BARBARA: Oh, we ought to be going back now.
GANATUS: Let’s make sure this is impossible first.
(They continue on and reach a dead end.)
GANATUS: Huh, I must have had sixth sense. Look at that…pity. Well, lets go back and try one of the other ways.
BARBARA: No, wait a minute.
GANATUS: Can you see something?
BARBARA: No, stand still for a minute…
(They stand and listen to a dripping noise.)
BARBARA: There! Can you hear it? The sound of water.
(GANATUS flashes the light upwards.)
(He plays the light over the walls of the cave.)
GANATUS: Yes, Barbara, look!
(He has spotted a small gap in the cave wall.)
GANATUS: There’s a passageway here.
BARBARA: Well, that won’t be easy…
GANATUS: It’s a good job we haven't been over-eating recently.
(He gives BARBARA the light, takes a coil of rope from over his shoulder and ties one end round his waist.)
GANATUS: It’s going to be a long crawl…well, we won’t use one of the customs of your planet.
BARBARA: What’s that?
GANATUS: “Ladies first!”
(BARBARA laughs and grabs the other end of the rope.)
BARBARA: Ha! I should hope not!
(GANATUS starts clearing small rocks away from the gap.)
GANATUS: Play the rope out as I move in, will you?
BARBARA: Yes all right. Be careful, remember what Ian said - we’re not to take any chances.
(GANATUS crawls in part way.)
GANATUS: (Mocking.) Do you always do what Ian says?
BARBARA: (Sternly.) No, I don't.
(GANATUS crawls back.)
GANATUS: Well, let me have the torch then, unless you think…?
BARBARA: No, no, your need is greater than mine.
(GANATUS crawls slowly into the gap as BARBARA feeds the rope slack as needed.)
GANATUS: (OOV: Within gap.) Barbara?
7: INT. CLEFT
(GANATUS is hanging by the rope and looking down.)
GANATUS: There seems to be a drop of about…thirty feet or so. I’m going down.
8: INT. CAVE TUNNEL
BARBARA: Well, be careful!
GANATUS: (OOV: Within gap.) Tie your end of the rope around a rock or something, will you?
BARBARA: Yes, all right.
(She finds a rock and ties the rope around it. She uses her foot as a brake on the slack and grips the end tightly.)
GANATUS: (OOV: Within gap.) Right!
(The rope is slowly played out, moving around the rock and through BARBARA'S hands and foot. The strain suddenly becomes too much and BARBARA is pulled over,
the rope flying through the gap.)
9: INT. LOWER CAVE
(GANATUS falls and hits the ground.)
10: INT. CAVE TUNNEL
(BARBARA jumps to her feet and shouts through the gap…)
BARBARA: (Shouts.) Ganatus!? Ganatus!?
(She turns and runs for help. IAN is already coming along the tunnel.)
IAN: What’s happened?
BARBARA: I couldn’t hold onto it…
IAN: Where’s Ganatus?
BARBARA: It slipped through my fingers. (Points.) He’s down here, look!
(They rush to the gap.)
11: INT. LOWER CAVE
(GANATUS is stood on the floor of the lower cave and looking upwards.)
IAN: (OOV: Shouting slowly.) All…right…this…end! Are…you…hurt?
GANATUS: No, I’m not!
12: INT. CAVE TUNNEL
(KRISTAS and ANTODUS have joined IAN and BARBARA.)
ANTODUS: Is my brother hurt?
BARBARA: No, he isn’t. But, it was my fault. The rope slipped off the rock.
(IAN grabs a rope off ANTODUS.)
IAN: The rope, Antodus!
13: INT. LOWER CAVE
GANATUS: (Shouts.) Barbara?
14: INT. CAVE TUNNEL
IAN: (Shouts.) Are you sure you’re all right?
15: INT. LOWER CAVE
GANATUS: (Shouts.) Yes! What’s happened to Barbara?
16: INT. CAVE TUNNEL
IAN: (Shouts.) She’s okay. Don’t worry! Hang on a minute, I’m bringing another rope down to you!
17: INT. LOWER CAVE
GANATUS: (Shouts.) It would be better if you came down here! There’s a big cavern with lots of tunnels going off it! Unless you’ve found
anything else, this seems a fair chance!
IAN: (OOV.) No, we haven’t! Hang on…we’ll be with you in a couple of minutes…
GANATUS: (Shouts.) Good!
(He glances round.)
GANATUS: (To himself.) It looks as though it may have been a lucky fall…
18: INT. CITY. CONTROL ROOM
(The DALEKS’ screen shows static. A report comes through to two DALEKS.)
DALEK: (OOV: Over tannoy.) Rangerscopes are recording great activity amongst the Thal people!
FIRST DALEK: (Into tannoy.) Are there pictures?
DALEK: (OOV: Over tannoy.) No, reception is bad.
(The FIRST DALEK spins round in a panic.)
FIRST DALEK: They are attacking our instruments!
SECOND DALEK: We must keep alert!
FIRST DALEK: Yes.
(It turns back to the panel.)
FIRST DALEK: (Into tannoy.) Concentrate all power of Rangerscopes and Vibrascopes on all entrances to the city.
19: EXT. CITY
(Bright lights flash on the towers of the Dalek city.)
20: EXT. FOREST EDGE
(The source of the light is a group of Thals reflecting sunlight off huge mirrors onto the city.)
21. EXT. CITY WALL
(The DOCTOR, SUSAN and ALYDON have reached the city and are stood next to a featureless metallic wall. The DOCTOR holds a thick branch like a club. ALYDON
holds the map.)
DOCTOR: It looks as if my plan has worked!
ALYDON: We can’t keep up this light reflection for long.
DOCTOR: Never mind. It gives us a better chance to get into the city unnoticed.
SUSAN: We can’t be sure of that, Grandfather.
DOCTOR: Oh, I know it’s risky, but, er…well, we mustn’t diddle about here. Now, I want to get to the east side of that antennae.
(He starts to wander off. ALYDON consults his map.)
ALYDON: Er, Doctor, look…
ALYDON: According to the map, we should be moving further to our left… (Points.) ...in that direction.
(The DOCTOR looks at the map.)
DOCTOR: Yes, yes, I see. Well, go ahead will you? (To SUSAN.) Go along, child.
(SUSAN and ALYDON move off.)
DOCTOR: (To himself.) Yes, we’ll show them a thing or two…
(He smiles to himself…)
22: INT. TUNNEL
(IAN leads his party down through a dark rocky tunnel. IAN and GANATUS have Thal torches.)
IAN: So far, so good. It seems to be broadening out a bit.
GANATUS: Who knows? It...may stop being impossible.
BARBARA: Just become unbearable.
IAN: Well, at least we can breath in here.
GANATUS: We seem to be travelling more or less in a straight line.
IAN: Yes, I think we are.
(The group stops for a moment. KRISTAS moves up front to IAN.)
KRISTAS: I’ll take the fire.
IAN: Oh, thank you.
(He hands the firebox over.)
KRISTAS: Shall I lead on then?
IAN: Yes, I suppose you might as well. We’ll…we’ll have a rest in a minute.
(The group continues on but ANTODUS hangs back, looking nervous. He calls to his brother.)
ANTODUS: Ganatus, I want to go back.
GANATUS: What for?
ANTODUS: I can’t go on anymore.
GANATUS: You must!
ANTODUS: No. We’re going deeper…deeper all the time. We’ll be trapped in the mountain, I know we will. Please, Ganatus…let me go back.
GANATUS: You can’t!
ANTODUS: But, you don’t really need me, not really! I could, well…I could go back and signal to the others that we’ve managed to get as far as we
(GANATUS looks over his shoulder to make sure that the rest of the party are not listening, then speaks firmly.)
GANATUS: Antodus, we go on together!
ANTODUS: Why? Why are you making me do all these things? Even if we do get through, we’ll never defeat the Daleks! Ganatus…we’re all going to be
GANATUS: We can’t turn back now!
ANTODUS: The others can’t…but we could. Listen…they’re going to die anyway. We could just go back and tell the others that the Daleks killed
GANATUS: (Furiously.) Oh what are you talking about - “you must go back”?
ANTODUS: I’m not going on.
GANATUS: You are! You must!
(ANTODUS turns to go, GANATUS grabs at him then suddenly ANTODUS cries out, holding the back of his head.)
GANATUS: Antodus? I’m sorry. Are…are you hurt?
(The sound of rock falling reveals the source of ANTODUS’ pain. The cave roof is starting to come down. GANATUS helps ANTODUS up.)
(IAN rushes up and the two manage to get out of the way just before the roof crashes down. BARBARA and KRISTAS also run up.)
IAN: (To GANATUS.) Is he hurt?
GANATUS: A rock hit him. It would have hit me, but he pushed me aside. He was very brave.
IAN: Well, I hope he hasn’t cut his head.
(The two kneel by him. ANTODUS is more angry and embarrassed than hurt.)
ANTODUS: I’m all right.
GANATUS: Ian, we can’t go back the way we came. (To ANTODUS.) We must go on now.
(ANTODUS looks distraught.)
23: INT. CITY. CONTROL ROOM
(Two DALEKS glide towards a control panel.)
FIRST DALEK: Emergency! Emergency!
SECOND DALEK: Reaction on the vibrascopes.
FIRST DALEK: Where?
SECOND DALEK: Section fifteen, city wall. Shall I redirect the Rangerscopes?
FIRST DALEK: No. If we track them by their vibrations, we can take them by surprise.
(They glide away.)
24: EXT. CITY WALL
(SUSAN spots a type of junction box set into the wall. A thick cable runs up from it.)
SUSAN: Hey, Grandfather, look!
(The DOCTOR and ALYDON run over.)
DOCTOR: Mmm, yes?
SUSAN: Is this what you want?
DOCTOR: Ah yes! A single cable. The whole city is powered by static electricity!
ALYDON: Well, how do you know that?
DOCTOR: The single wire, you see.
(He points out the direction the cable takes above them and round the top of the wall.)
DOCTOR: Round here…there…see? And there…that must be the answer!
(SUSAN has also been tracing the cable’s track round the buildings with her finger.)
SUSAN: Well, it leads up into the antennae!
ALYDON: Well, it certainly goes in that direction, but I...I can’t see it all.
(SUSAN turns back to the junction box and starts to try and prise its glass front off.)
SUSAN: I wonder if I can open this box…?
SUSAN: There aren’t any hinges on it.
(She suddenly pulls up the glass cover.)
SUSAN: Well, that’s it! Look, look, it slides up!
DOCTOR: Ah, good girl! Now, just take it over there…that’s it.
(SUSAN places the glass cover to one side.)
DOCTOR: Now look out.
(Using his club, the DOCTOR smashes the circuits in the exposed panel.)
SUSAN: The thing is, how are we going to cut the wire now it’s exposed without getting a terrific shock?
ALYDON: Look, we can’t wait around here too long, you know.
DOCTOR: No, just a minute! Now, you go and tell your friends to stop flashing the light on the antennae. Because for all we know, the Daleks might have a
beam to throw on them - paralyse them, kill them!
ALYDON: But I can’t leave you two here.
DOCTOR: Oh, we shall be all right. Now, go along…and tell them to move their position from time to time. Now hurry please!
ALYDON: (Flustered.) Very well then, but don’t waste time here. I…I’ll come back for you if I can.
DOCTOR: Yes, yes, yes, yes, we shall be back before then. Now go!
(ALYDON leaves. The DOCTOR watches him go.)
DOCTOR: Dear, dear, dear, that young man gets so agitated.
(SUSAN smiles as the DOCTOR turns back to the box.)
DOCTOR: Now, I’ll tell you what we’ll do. We’ll short-circuit it to...another conductor. Let me have the key of the ship, Susan, will you…?
DOCTOR: The key of the ship, dear!
(SUSAN takes the key chain from round her neck.)
SUSAN: Oh, what a good idea, yes!
(The DOCTOR puts the chain with the key attached over the end of his club.)
DOCTOR: Yes, yes, yes. I can always make another one if necessary.
SUSAN: Yes, of course.
DOCTOR: Now, let us, er…proceed.
(Using the club, he places the key into the panel. He pulls the club away leaving the key there.)
DOCTOR: Now, the power’s running away. (He laughs.) That’ll teach the Daleks to meddle in our affairs!
(SUSAN laughs then points to a smaller junction box next to the large one.)
SUSAN: What about this one?
DOCTOR: Well, of course!
(Using the club, he smashes the glass away, the puts the free end of the necklace into the second box. There is a small explosion….)
25: INT. CITY CONTROL ROOM
(…And a larger explosion under one of the panels in the control room.)
26: EXT. CITY WALL
DOCTOR: Now, we’ve short…we’ve shorted it, you see? So something must have gone somewhere else! The extent of the damage, of course, we don’t
SUSAN: Look, Grandfather, this is marvellous, but...but they must have a fault locator somewhere. We must get away from here!
DOCTOR: (Boasting.) But, my dear child, don’t you realise what I’ve done? A few simple tools...
SUSAN: Yes, but we mustn’t...
DOCTOR: ...a superior brain?
SUSAN: ...waste time, we must go now!
(They turn to move but are caught in a bright light and surrounded by a host of DALEKS.)
27: EXT. TUNNEL
(IAN is at the head of the group. He suddenly stops dead.)
IAN: Look out!
(The others stop.)
IAN: No place for a quiet stroll, is it?
(Ahead of them the floor drops away into a chasm.)
GANATUS: It looks pretty wide.
IAN: Yes, and deep.
(He speaks to the others behind him.)
IAN: Well, you might as well take a rest while we sort this one out.
(The party sits down while IAN plays his flashlight over one side of the chasm.)
IAN: No point in going that way. It widens out.
(He looks at the other side beside them.)
IAN: There’s no foothold at all on this side.
(He looks at the other side of the chasm opposite them.)
IAN: There’s a ledge over there, look. About two to three feet, would you say?
(GANATUS looks across the chasm.)
GANATUS: There seems to be some sort of cleft in the rock face...there.
IAN: Yes, I think you’re right. We’ll have to get over there.
GANATUS: How about...going down this side on a rope, and trying to climb the other?
IAN: Yes, well, see how deep it is. Hold the torch...a pebble?
(IAN picks up a pebble and drops it over the fissure. Several long seconds later, it hits water. The chasm is too deep. They look at each other in silence.
After a long moment…)
GANATUS: How do we do it?
(IAN thinks for a moment, then…)
IAN: We jump.
(GANATUS points the torch at the opposite ledge.)
GANATUS: There’s not much space to land in.
IAN & GANATUS: Oh, well, I’ll go…
(They stop. IAN smiles and takes the rope off his shoulder.)
IAN: You go and tell them we’re going to jump.
(IAN ties the rope round his waist. GANATUS turns to the others.)
GANATUS: We’re going to jump it.
(The others get to their feet. GANATUS rejoins IAN.)
IAN: Shine the torch on that ledge. Keep clear of me when I run...and give me plenty of rope.
BARBARA: Good luck.
(IAN squeezes her arm in thanks. He takes several steps back away from the fissure, makes a test run, goes back, takes a deep breath, runs and jumps and
catches the ledge. He gets his foothold and stands to face his companions on the other side.)
IAN: All right! Ganatus, you come over next and we’ll explore that cleft in the rock.
(IAN tests the stability of the ledge with his foot.)
IAN: Quite firm. I think there’s just about enough room for two of us.
(GANATUS ties another rope round his waist.)
GANATUS: Take up the slack will you?
(GANATUS throws the other end of the rope over to IAN, who catches it.)
BARBARA: (To GANATUS.) Good luck.
(GANATUS smiles and walks several feet back.)
IAN: Right, take a good long…run.
(GANATUS runs and jumps safely into IAN'S arms. He gets his foothold.)
IAN: Good jump! You should have come first.
GANATUS: Now I’ll take a look at this cleft. (To BARBARA.) The torch?
(IAN winds the slack of GANATUS’ rope around himself. GANATUS holds out his hands and is thrown the torch by the others.)
GANATUS: Pay it out slowly.
(GANATUS slowly rappels over to the cleft, using the rope to keep himself from falling.)
GANATUS: It’s all right. There’s…a handhold just here.
(He moves out of sight round the corner of the thin ledge into the cleft.)
GANATUS: (OOV.) A little more rope…
(IAN pays it out.)
GANATUS: (OOV.) It goes wider. It seems to be some sort of a tunnel. I…I don’t need the rope anymore. Bring the others over.
(GANATUS has untied himself. IAN pulls the rope back.)
IAN: Right. (To the others.) Rope coming over…
(He throws the rope over. They catch it. IAN takes a deep breath.)
28: INT. CITY. CONTROL ROOM
(The DOCTOR and SUSAN are sat on the floor surrounded by DALEKS.)
FIRST DALEK: You have destroyed our videoscope and one of our lifts.
DOCTOR: And you in turn killed the Thal leader in your ambush. You will be responsible for more deaths unless you help these people.
FIRST DALEK: The only interest we have in the Thals is their total extermination!
SUSAN: (Startled.) What do you mean?
FIRST DALEK: Tomorrow, the atmosphere will be bombarded by the radiation from out nuclear reactors.
SUSAN: (Shocked.) Why are you doing this?
DOCTOR: That’s sheer murder!
FIRST DALEK: No - extermination.
DOCTOR: But you must listen to reason. Please, you must!
FIRST DALEK: Without radiation, the Dalek race is ended. We need it as you and the Thals need air.
(All the DALEKS turn and raise their arms in a salute.)
DALEKS: (In semi-unison.) Tomorrow, we will be the masters of the planet Skaro!
29: EXT. TUNNEL
(BARBARA makes the jump and lands safely in IAN’S arms.)
BARBARA: Oh, I thought I…I wouldn’t make it!
IAN: You did well. Just get your breath back for a minute.
BARBARA: I’m all right.
(He unties her rope. As he gathers the rope back up, she edges towards the cleft but facing the chasm. She realises her error and falters…)
IAN: Oh no! Not that way!
(He reaches out and grabs her hand.)
IAN: Now stay still. Give me your other hand. You’ve got to come back. Now swing!
(He pulls her back.)
IAN: Now this time, face the rock.
(She does so.)
IAN: And reach…reach round with that arm.
(She slowly edges around the cleft.)
IAN: Reach higher…can you feel?
BARBARA: I…I can’t reach!
(She tries again)
IAN: Higher, go on!
BARBARA: Ah, yes!
IAN: Now...let go of my hand and...swing yourself around. Go on!
(She does so and swings out of sight into the tunnel.)
IAN: All right?
BARBARA: (OOV.) Yes!
(KRISTAS calls out from the other side of the chasm.)
KRISTAS: I’ll throw the fire.
(IAN catches the firebox. He gathers up the rope again.)
IAN: Rope coming over.
(He throws the rope to KRISTAS.)
KRISTAS: Will you go next, Antodus?
ANTODUS: (Sullenly.) No, you go on.
KRISTAS: Very well.
(He ties the rope round his waist and follows the jump taken by his companions, again successfully.)
IAN: You made it look easy.
(KRISTAS unties himself and makes his way towards the cleft.)
IAN: Got the grip?
KRISTAS: Yes, I'm clear.
(He moves out of sight into the tunnel.)
IAN: (To ANTODUS.) Rope coming over.
(IAN throws the rope over but ANTODUS stands looking into the chasm as if mesmerised and doesn't even attempt to catch it.)
IAN: Sorry, bad throw. My fault. Move back from the edge.
ANTODUS: (In a scared whisper.) I can’t do it…
IAN: (Firmly.) Move back from the edge and catch this rope! Ready? Coming now!
(ANTODUS does as he is told and catches the rope.)
IAN: Good! Now...tie it round yourself.
(He does as instructed.)
(ANTODUS tightens the knot.)
IAN: Now…give yourself a good long run…and jump.
(ANTODUS takes several steps back…)
IAN: I'm ready whenever you are…
(ANTODUS braces himself, runs and jumps but hits the ledge badly and, with a scream, falls into the chasm. IAN is knocked to the floor, tied to the other end
of the rope. He grabs hold of a rock but with a poor grip…)
30: INT. CHASM
(ANTODUS spins on the end of the rope in the chasm. He tries to grab a hold of the rockface but it's completely smooth.)
ANTODUS: (Hysterical.) Help me! Help me! I can’t hold on! I can’t hold on!
31: INT. TUNNEL
(IAN'S grip on the rock is reduced to his fingers only as the weight of ANTODUS pulls him slowly nearer the edge…)
