The Doctor and Susan are still in that sink, Barbara. And he's turned the tap on. They've put the plug back in again. Oh, it is for safe here. Yes, if they fill that sink with any more water... Yes, of course it'll come in here, down the overflow pipe. Exactly. I'm getting used to these sounds. I think that last one must have been the door closing. Are you sure they have gone? I'm not sure of anything, Barbara. Ian, the Doctor and Susan, they must have been drowned. We don't know. We must go and find out. Stay up there if you want to. No, I'm coming with you. All right. Anything? No, too dark to see. I'm afraid there's not much hope, Barbara. What are we going to do? I mean, like this, what can we do? I said they'd be all right, Grandpa. You don't believe it. There they are, you see, my friends. Pretty much as easy as all that. There we are. The report is ready. What are you doing now? The report itself isn't final enough. Farrah would have telephoned his department. But you can't do that, you'll give yourself away. They'll know it isn't him speaking. You leave this side of it to me. Strange operator here. Hello? Yes, London, yes. Whitehall. W-H-I. Yes. Eight-seven, thank you. How do you know who to speak to? I've been dealing with these people for years. The eight-seven? Yes. Hold on, I have a call for you. Go ahead, please. Hello? Is Mr. Whitmore there, please? Arnold Farrow speaking. Yes. Oh, hello, how are you? Good, I'll hold on. The secretary asked me how I was. Told you I'd be all right. Doesn't sound like Mr. Farrow at all. The tests are very satisfactory. I'm sending in the report. Yes, it is a bad line, isn't it? Well, I would say the DN6, as they call it, is about 60% improvement on normal insecticides. Yes, I know I'm not usually so enthusiastic, but this is really extraordinary. Crossing over to France tonight. And I'll send in the report. Will you send in the authorization? Good, I'll tell Forrester. Yes. Goodbye. Well, perfect. As soon as they get the report, we'll get the go-ahead. Certainly wasn't here before. Half dried and half righty. Ian, it's a formula. Yes, I believe you're right, Susan. Do you think it's the formula for the insecticide, Doctor? Perhaps. Well, if it is, it'll tell us what we're fighting against. We might even find a cure. A cure? What's the good of that? I don't know. Neither do I. If we're going to do anything at all, we must stop it. Yes, Ian's right, Barbara. You only need a cure if someone infects it. What we've got to do is stop it being produced. Yes, all right, Susan. Well, I think we should take a closer look at this oversized document. The more we know about the enemy, the better. Well, those things up there are definitely molecular structures. Yes, you're quite right, my boy. I only wish I could see it more as a whole. Well, couldn't we lever it up in some way, stand back and look at it? Yes, it'd be like a huge advertising poster, wouldn't it? I'm afraid it's far too heavy. We'd never lift it. Let me have the notebook, child. Now, we shall have to make a map of this. Now, Chesterton, you start marking off the section with your feet, will you? Yes. And Susan and Barbara, I want you to call out to me what you see written beneath you. Yes, yes, this is the insecticide quite clearly. It's a bit rough, of course, but it tells us the story. Yes. I'm not very well up in this, Doctor, but isn't that phosphoric acid? Oh, this indicates the amount of organic esters. Yes. And this is mineral nitrate. Mm-hmm. That's about as far as I go, I'm afraid. My dear boy, this formula's quite clear. Look, we've one vital difference. The inventor has made the insecticide everlasting. That means it would seep into the soil. Get into the drinking water. What about human beings? Well, given insufficient quantity, of course, it's capable of killing human beings. Yes, if they drink and eat infected food and water. Yes, or even coming in contact with it. Penetrating the skin to get into the bloodstream. Well, then why do we go on just sitting? Now, now, now, my dear, gently, gently. I'm sorry. Barbara, are you all right? Yes, I feel a bit giddy. I think I must be hungry. Yes, now there's another point to consider, my dear boy, eating. We can't, even if we do find food here. Yes, well, the less we talk about food, the more I like it. We can go back to the sink, of course. The water in the tap is quite safe. Well, no need for all of us to go. I'll go and fetch some. Ah, but I want to go into that direction. You see, there's something over there that might be the solution to all this business. Well, what's that? A telephone, my dear. Hmm? Ah, come on, then. Let's go. Hmm, it's climbable. Yes, the thing is, my boy, how heavy is that receiver? Grandfather, I think I've got just the thing. Look, and push this underneath the receiver. Hmm. Yes, there are lots more over there. Hey, are you all right? Yes, I'm fine. I told you, I haven't eaten for ages. I think that's what it must be. Don't make a fuss. Well, Susan, you and I will do the climbing, eh? Yes, all right. Doctor. Huh? Pass this up to Susan, and she can then pass it on up to me. Very well. All right, I'll get started. Can you manage all right? Yes, I can make it. Oh, well. Barbara, would you mind bringing another one of these, please? Ah, thank you, my dear. You look very tired. Yes, I am a bit. Well, we can manage. You better all come up now. Coming! Yes, Barbara. Barbara. You think that we three can manage, huh? Why? Well, I don't think Barbara's quite up to it. Oh, all right. Well, we can try. It's all right. I'm here. Oh, good. Now, listen, Susan. We're going to try and lift this end. Hmm? Now, you, when we get it lifted up, push this cork underneath. All right. All right? Yes. Are you ready? Yes, yes, yes, yes. Barbara? Yes. Right, now, lift! All right. Quickly. Ah! Oh, God. Right. We'll try the other end now. There we are. Same thing, Susan. I think it's right. Ready now? Lift! Ah! Right. Oh! Ah! Oh, we did it. Hilda, come and answer this thing. It's driving me mad. The old farmhouse again. Hello? What number do you want? Can you hear us? Put us through to police! Any luck? No. Nothing at all. We can't have failed after trying so hard. Yes, I'm afraid we have, and it's my fault. I thought it was worth trying. Well, we must try again. Oh, yeah, I don't think we'll do any good. Oh, we must try. I'll go and tell Barbara. You've been overdoing things. Yes. Yes, I think I have. I'll go and get you some water. It'll freshen you up, eh? Thank you. What are you doing? I want your handkerchief. I'll tell you. No. What's the matter? You can't have it. You mustn't touch it. Barbara. No one must touch. Barbara! Here, the same aboma, insecticide. You didn't eat or drink anything? Oh, no, certainly not. She got insecticide on her hand. She touched it. Well, she never told me. I never saw her do this. She did borrow my handkerchief. Where were you then? By that pile of seeds. Yes. You see, she got it on her hands. And she rubbed it off on your handkerchief. Why didn't she tell us? You can help her, can't you, Doctor? Then, Father, we can do something, can't we? What happened? Did I... You fainted, that's all. The insecticide. Is that why I feel like I'm dying? Is that why I feel like this? Yes, you got some of it on your hands, and you didn't tell us anything about it. It was very wrong of you, wasn't it? Am I... No, no, no. This little attack you've experienced is only temporary. Take it easy, Doctor. Come on, take it easy. What can we do for her? Well, the surgeons will get her back to her normal size, but at the moment, her protective cells are too small to cope with the molecules of poison in her bloodstream. But if we can, that dosage of insecticide will be 70 times less dangerous. Practically nothing at all. Are you sure? Yes, so quite sure. But we must get her back to the ship. What are we waiting for? How are you feeling? Oh, a bit ropy. Could do with a glass of water. We're going to take you back to the ship. All right. Just give me a minute. Come on, Margaret. We've got a long way to go. You can get us back to normal size, can't you, Doctor? Oh, yes, of course I can, dear boy, yes. Of course I can. I hope. What the devil's wrong with this phone? Margaret, you're ill. You've got to let us take you back to the ship. You could die. Doctor, make her see some sense. There's nothing I can say, dear boy. Barbara's quite right. Susan. We must find a way to stop it. We must. Any other phones around here? Oh, yes, there's one in the lab next to the sink. Maybe that's where the trouble is. Perhaps the phone's off the hook or something. Yes, I'll go and see. I want to have a look at Farrow's notes. Why? Yes, that's it. We'll cause trouble. Start a fire, my boy. Yes. Can we start a big enough one to do any real damage? Well, we can try anyway. I suppose if you'd like a good fire, it's there. What do you think, Barbara? I think it's a good idea. If we could manage to start a fire, it would certainly attract people here. Yes. We'll find that man's body. Yes. That's it. What? If we could only turn it on. Well, then what? I'll soon show you. Hey, look out! Quick, behind this water tap. Who put these under the therm? DM6. It's DM6. Come on, I want an explanation. Why did you put these under the therm to stop me using it? Hold it! That's not important now. Of course it's important. Will you listen to me? Oh, you've replaced your receiver now, have you, Mr. Smithers? This isn't Mr. Smithers. The extension was left off. I'm sorry. Is that Mr. Farrow? Farrow? No. Oh, the other gentleman, I see. Only I've a call for Mr. Farrow. Oh, uh, just a minute. Do you think you ought to be doing this, Elder? Shh, listen. Farrow here? Who is this? You see? It's the same man. Get him to talk a bit more. Mr. Farrow, I've got a London call for you. Will you accept the charges? London? Oh, uh, yes, uh, yes, I'll accept the charges. Uh, all right. Hold on, please. Yes, they do sound alike, I must say that. Perhaps I had better go up there. Hello? Mr. Farrow? Yes? I'm sorry. London has broken the connection. Perhaps they'll call again. Oh, uh, very well. Thank you. It's the same man. No doubt about it. We'll soon find out. Oh, I think it's moving a bit. Oh, come on, all together. It's coming. Ian, the tap's ready to turn on now. Good. Now, Susan, I've wedged the matchbox against a knot hole. What we're going to do is run at the side of it. Hmm? Like using a battery ram. That's the idea. Here. Come on, get a hold of it. Right. All right? Yes, I, I think that's got it in about the right angle, at the gas jet. Yes. Hmm? Well, all we succeed in doing is, is just melting this tin. No, no, no, no, I've had a good look at this. This is pressurized. It's a spray kind. Our problem will be, will be to get it away far enough to, when it explodes. Explodes? Oh, yes, it's going to explode. And when it does, it'll go off just like, well, to us, a thousand pound bomb. It's killed everything. Everything. Smell this. Oh, dear boy, try hitting the box at a sharper angle. More force, more dip. Hmm? Doctor, have you ever tried to lift one of these things? Come on, Ian, let's try again. Charge! Yes, come on. Turn it up. Turn it down a bit. You don't want us burned alive. Doctor, Barbara, get behind that tap. Get behind, that's it. Take it easy, eh? Easy. Then he told me he couldn't authorize DN6. I had too much money sunk into it. I had to kill him. Once I'd started, I had to see it through, all the way. Can't be long now. Take as much cover as you can. When that thing explodes, there'll be metal flying all over the place. It'll be just like that air raid, Grandpa, do you remember? Yes, very well. And what infernal machines those zeppelins were. Forrester, think what you're doing. DN6 is more deadly than radiation. Doesn't that mean anything to you? Get the briefcase. It's worked! It's worked! Come on, all of you, back to the ship. Take care of Barbara. Quickly, quickly. Doctor, what are you doing? That thing's covered with poison. Yes, I know it is. I know all about it. Well, what do you want it for? You'd be surprised. Go on, leave it on. Well, there. Now I have some questions that need answering. And turn that gas off, you'll kill a lot of us. You've got to repeat exactly what, the things that happened to us when we landed. Is there anything I can do? Yes, that seat over there by the chair. Take it over to that table. So that we can all see it and wrap that around it when you do it. Doctor, Doctor. I think it's working. Yes, I think it's working, my boy. Doctor, look at that seat. Yes, yes, we've done it. Doctor, it's incredible. That seat, it's completely vanished. Oh no, my dear boy, no. Look, you see? It hasn't vanished at all. Barbara? I'm so thirsty. There you are, drink your tea. It's there. It's there. It's there. It is. It's there. There is no more poison. No more poison. No more poison. I'm sure. I'm sure it is. It is. It is. It is. It is. It is. It's there. It is. It's there. It's there. It is. It is. There you are. Drink that. Oh, I had no idea water could taste so good. Well, well, here we are then. The patient is beginning to look her usual self again. Thank you, Doctor. Not at all, my dear boy. Oh, is that your service? Doctor, what happened in the laboratory? I don't remember much after the explosion. Well, I'm happy to say our plan worked. We didn't have to fire the laboratory. But we did attract attention. Do you know a policeman came into that room just as I was about to climb down that pipe? Oh, good. Now, what about us? Can you get us back to normal? Yes. There's your answer, my dear. Grandfather, is that the seed you brought in with you? The same seed. Then we are back to normal. Completely, my dear. Now, before I check up and see where we are, I suggest you all go and have a good scrub. Oh, yes. Off you go. Oh, dear, dear, dear, dear, dear. Now, is that irritating? I had to repair that wretched thing and... Now, look at it. I can't see a thing. Wait. I... I think we're beginning to materialize. Perhaps I should know now where we are. The End
