Keep your head down. They haven't seen us yet. Doctor, look! There's more of them! The enemy time machine is in this area. We can locate the position with our seismic detectors. Find and destroy it. The remainder will search for the humans. Are they to be taken alive? No, they are to be exterminated. Good. Exterminate it. Let the search begin. Stay down. One of them is coming this way. We must find the TARDIS before they do. Yes, and we must warn Ian and Vicky. They don't even know the Daleks are here. Yes, we'll warn them, but we haven't seen them for hours. Anyway, it's no good hanging about here. Come on, let's get moving. Yes, scream, you little fool, run! Don't just stand there gaping, you nit! Come on, back! Wait. Tracks of the humans. Follow them. Wait. Perceptor indicates someone is near. It draws closer. Destroy on sight. An Iridium, one of the species that inhabits this planet. Unimportant. Continue the search. This desert was once a vast ocean. We, the Iridiums, lived in a city beneath the sea. But for a thousand years, those twin suns that burn have moved closer and closer. Then, then the seas dried up and all the creatures that lived within their waters perished. All but the Maya beasts. Maya beasts? What are they? They lived in the slime at the bottom of the ocean. When the waters were gone, they invaded our cities. There were too many of them. We tried to destroy them. They multiplied too quickly for us. We were driven back as the Maya beasts took over more and more of our beautiful city. And these Maya beasts, what do they feed on, hmm? They are flesh eaters. You mean they attack humans? Of course. Oh, gracious. Doctor. Look, two of our friends went out into the desert. Will you help us find them? When did you see them last? Last night. The Maya beasts hunt at night. Do you think they are near or far? Oh, I don't think they could travel far on this sand. Then they might have gone through the Tartarian airlock into the tunnels. Then it is too late. What do you mean it's too late? It is to be exploded. Exploded? Yes, the airlock. You see, we Eridians have learned the only way to destroy the Maya beasts is to entomb them in the sections of the city they have occupied. The Tartarian airlock will be detonated at high sun. Well, then we must stop it. No, we would not reach the airlock in time. Well, I shall try. Look, where... Where is this place? If we move faster than the sun, we will try. Follow. High sun. Ian. Oh, Ian. I'll get help. I'll find a doctor and get help. We have arrived. This is the gate to our city. I'm afraid I can't see any signs of a city. This old airlock, we used it when our city was beneath the sea. It will take us to a part of our home that is still free from Maya beasts. I see. Well, we're very grateful for your hospitality, but I must warn you, the Daleks are right on top of us. And I don't want either you or your people involved in any of this dangerous business. If they knew you'd given us shelter, they'd show no mercy. No matter. First, you need food and rest. Then we will help you search for your time machine. Spread it. Spread it. Open the lock. Please enter. There is no danger. Barbara. Barbara, my dear. Come on, come on, come on. The seismic detector is registering a contact. The enemy time machine is beneath the sand at this point. Then it was buried by last night's storm. It must be uncovered before we can destroy it. Yes. We will take some Eridian's prisoner. Yes. And use them to dig the ship free. Yes. Well, see to it. I obey. I think this is absolutely delicious. It's a most unusual flavor. How can you sit there eating when Ian... Oh, my dear, you think I'm being callous, do you? Yes, I do. And I think it's pure supposition that they've been caught by those Maya beasts. After all, we weren't. You haven't much faith in Ian's infallible self-preservation, have you? I'm sorry. This place gives me the creeps. Oh, rubbish, my dear. Rubbish. I think it's fascinating. Yes. You could almost call it beautiful. You know, I think you're tired. Close your eyes and try and get some rest. Go on, go on. We must conserve our strength if we're going to get back to the TARDIS. Yes. Now that we can get back to the TARDIS. Ah, Mouser. You enjoyed your meal? Oh, indeed, yes, indeed, yes. Yes, it is a most unusual taste. You know, I've been taking stock of this place, having a jolly good look round here. Tell me, why is this opening walled up, hmm? It's led to a part of our city that's been invaded by Maya beasts. It is the same all over. We have to block off tunnels to stop their advance. Do please sit down. I have some news for you. Ah, what is it? The leader of the Daleks has communicated with us. They have issued an ultimatum. Yes, I suspected something of that kind might happen. What is it, hmm? We hand you over to them or they will destroy what remains of our city. They mean what they say. They don't make idle threats. Have you replied? Not yet. The elders are still discussing it. We have a half son in which to give them our answer. Hmm, you haven't much choice, have you? Well, I don't propose to inflict our troubles on you, sir, so I think we'll leave and take our chances. No, no, no. The Daleks have said that we must hand you over, not set you free to try and escape. You mean? You must be our prisoners until such time as our arrangements with the Daleks have been completed. Then, if the elders agree, you will be given into their custody. The digging is completed. Are the prisoners to go free? No, they are worthless, inferior creatures. They have no value to us. Destroy them. There. Destroy the enemy time machine. Use full power. Fire. Again, fire. It is undamaged. It must be constructed of a material that can resist our neutralizers. Failure. Remain on guard until the prisoners have been handed over and exterminated. We obey. Are you feeling better? Yes. What's happened? Well, it's not too good, I'm afraid. This looks like bad news coming now. Bad news? What bad news? The elders have made their reply to the Daleks. They must be told. Well, have you eaten? What is the news? You are to be handed over at last, son. The Daleks have promised that when the execution is over, they will leave Aridius unharmed. You're... you're going to hand us over to the Daleks? We have no choice. The elders have so decreed. Please. They have no choice. Yes. But... but just to be handed over like that? Two hours. Their sons are due to set in two hours. Vicky. Vicky! Vicky! Let's go. No! Doctor, where does this walled up section lead? Oh, it's another part of the city. I believe. The part that was invaded. Vicky! Vicky, where's the end? Miss here, is Chesterton all right? He got a bad knock on the head. I made him as comfortable as possible and came to get help. It might have been better if you'd stayed where you were. No, it wouldn't. Because on my way here, I found an exit out of one of the tunnels. And just to our right, there was a small room. I found an exit out of one of the tunnels. And just outside it, the TARDIS. Ah, well, well, well now. That puts a different complexion on the matter. Tell me, my dear, this tunnel, would you know how to find it again? I'm sure of it. A big iron door. Just beyond that opening, over there. Doctor, maybe things will be all right after all. Yes, darling. It is time. I am to take you to the main airlock. No! No! Down here. Are you sure this is the right way? The prisoners have escaped from the Iridians. Are we to proceed with the destruction of the underground city? The Iridians have one hour to recapture the humans. If they fail, we act. I understand. The humans may try to reach their machine. Remain on guard. I obey. Barbara! It's all over your face. It looks worse than it is. The TARDIS. It's only 20 yards away. But there's a Dalek guarding it. We must get past it. I've got a very good idea. You two go first. You get out of here. And there's a ridge of sand on the left. Now you take cover. You get in a good position where you can nip in. Nip in what? The TARDIS. Yes, yes. Come on. Barbara, could I have your cardigan? Not again. It's for the Dalek, not for me. Here. I hope it suits him. Here you go. Doctor, your coat, please. My dear boy, we're trying to beat the TARDIS. It's not the start of the jumble sale. All will be revealed in due time, Doctor. Your coat. Dear, dear, dear, dear, dear. What are they going to do, Barbara? I don't know. Try to get the Dalek away from the TARDIS, I should think. What is the point of all this, dear boy? Doctor, with any luck, with your coat and Barbara's cardigan, we're going to make a trap. We're going to lure the Dalek over this trap. And with any luck, it'll fall down here. That's a good scheme. Yes, that's a good idea. Keep down. But how? I don't know. Wait and see. Right. I hope it works. All right, Doctor. Now I'm going first. And you follow. You keep on that side. You keep plenty of cover, eh? All right. Careful. Ooh, Dalek! Over here, friend! Ooh, Archie! Oi! Over here! Oi! Try and get out of that hole, Fred. Well, that got rid of that one. Look! Quick, into the box! Cease firing! They have escaped! Final termination is inevitable! Eradicate! Obliterate! Annihilate! We will embark in our time machine at once! The Dalek Supreme has ordered they are to be pursued through all eternity! Pursued and exterminated! No! No!
