Jerry and Joan are in a Euclidean submarine on their way to aid in the capture of Johnson and the Gregory rescue boat. Captain Bradford and Mrs. Gregory have been left on the captive yacht inside of one of the submarine locks on the Magic Island. They have just heard a radio message from Jerry to Johnson, advising Johnson to bring his boat to the island at once. Knowing this means Johnson's immediate capture, Mrs. Gregory and the captain are sure Jerry is being compelled to send the message by someone aboard the submarine. Just as the captain and Mrs. Gregory start to do something about it, they hear a rush of water. Captain Bradford runs out on the yacht deck and sees water pouring into the lock. Hurry up, Pat. Get out here quick. We've got to leave this boat. What's the matter, Tex? That water rushing... is it... the lock gate's broken. Yeah, our only chance to is to find in this yacht and run up that ramp to the inside chambers of the island. But this boat will be ruined and all our equipment's on board. Can't help it, dear. Come on. This place will be flooded in a few minutes the rate that water's coming in. I don't see how it happened. That gate doesn't look... Never mind how the gate looks, Pat. Come on. We've got to get out of here. All right, Tex. Do we have to walk on this narrow little rock ledge here? We do and be glad to get it. Come on. This noiseless paint on everything. I'm getting as bad as Jerry. I could only hear some noise when I walk. Yes, well, at least Jerry and Joan are better off than we are now. They're underwater. But they're in a boat that was made to be there. Right here, Tex, was where the door opened when G-47 came through it. It won't be so simple for us to open one. No, I think it was further back up this ramp. No, Tex. I was watching as he went back out the door. And that light, that bracket on the wall, was on the other side of him. Now, hold on, then. You mean that as you looked up here from the deck of the yacht, G-47 was between you and this light? Yes, I'm sure of it. He made such a weird figure as he stood silhouetted against that light. Well, then, that door is nearer somewhere. We'd better not be too long finding it. The light, the water's rising. We can try pushing on this wall. Right here, I think. No, no, good. Things on this island don't work automatically. They don't work at all. We've got to figure out how to get out of here pretty fast. Are that water? Tex, the water isn't rising anymore. Huh? What? Not rising? No, it's nearly still now. But it couldn't have stopped. We're 50 feet below the water level now. With the whole island submerged, what could stop the water after the lock gate broke? I don't know, but you can see for yourself. The roofs of the cabins haven't touched the top of the lock yet. And they were only a few feet below it to start with. Right, Pat. Only about two or three feet of water came into the lock when the gate broken. That's funny. I wonder. What, Tex? That's it. The island is rising again. That lock gate must be up to the water level now. Come on, let's go back down on the deck where we can take a look at it. But why isn't the light showing through the broken gate if we're above water? Because it's a couple of hours yet until daylight. Come on, we'll go back down and have a look at that gate. All right. Like Jerry, I'm glad to hear our shoes make some noise. Sounds like home, all right. Now come on up to stern, Pat. Captain. There's the skipper, Tex. I thought he and the engineer had been taken to one of the cells on the island. Well, he's here now. He didn't try to get out of this thing like we did. Something funny here. Yes, skipper? What is it? Gates. We saw the gate breaking? No. But we did, skipper. The gate broke and the water rushed in. No. That gate didn't break? No. Well, what happened then? Opened. The gate opened? Aye. So it wasn't an accident then. Our dear friend G-47 must have decided we'd been around here long enough. Not that, Tex. If someone had tried to drown us, the water wouldn't have stopped as it did. How about it, skipper? You seem to have kept your head and found out a few things. What stopped the water? Gate. The gate was closed again? Aye. But there must be some idea back of all this. These Euclidians are too busy now with the fleet of battleships playing around overhead and Jerry and Jonah out in one of their submarines. No. It doesn't make sense for them to stop and fool with these lock gates. Come. Skipper's got something to show us. We sign him on for the next cruise. It's going to be in his articles that he add a few more words to his vocabulary. Guessing what he means is getting on my nerves. Oh, steady Pat now. Skipper's all right. Maybe he doesn't talk much because he hears the rest of us talk too much. Look. Tex, the skipper's right. The gate hasn't been broken at all. That's plain enough, but why was the water turned in here? Look. Where? There. Down in the water? I can't see much. Dark down there. Got a flashlight, skipper? Here. Thanks. Now then, we'll have a look. Well, I can't see anything down there. There. Oh, Tex, I see it. It's a fish, a big one. Silver colored. Peculiar shape, isn't it? Biggest fish shape like that I ever saw. What is it, skipper? Torpedo. What? Torpedo. Torpedo, eh? Aye. Then we're on the wrong boat. That thing's going to go off when it jars against this yacht. Duh. You mean the torpedo is dead? It won't go off? Aye. I'm beginning to see this thing now. Skipper, did you see that torpedo come in here? Aye. Was it an accident? No. But how could a torpedo be brought in here? Magnetism. Oh, then the Euclidians knew just what was going on. Of course. I don't know why, but I can guess who. G-47. Precisely. Oh, you startled me coming out of the wall like that. So you tried a little experiment on us, eh? You were not considered. I'll say we weren't. We might have been drowned. That would have been no loss to me. But your destruction has no value in this plan. I merely wanted this torpedo, a stray shot from the fleet overhead. You used your magnets to pull this torpedo in here after it was shot in target practice? Precisely. I wanted to examine this type of projectile. I will send my assistance for it. You may follow me if you care to see what is happening in this submarine. Tex, we can go and see what Jerry and Joan are doing. We'll take him up on that. See you later, Skipper. Aye. Why, there's a door in this wall within arm's length. Now here, step over the rail carefully, Pat. We'd better hurry and not get too far behind old G-47. Might get lost. Gee, what is it, Joan? I don't like to just sit here and do nothing while that girl commander does as she pleases with the submarine. It will do you no good to attempt interference, Jerry. We are comparatively safe only so long as you restrain yourself from well-intentioned, though ridiculous and quite obvious, approaches to the subject of possible intervention in this Euclidean plan. Hey, quit talking like that. I've got enough of a headache now without any big words. We've got to figure what to do when we get on the Johnson's boat with this submarine. I can use little words as well as you, Jerry. You are a fool. I'm a witch? There is no shorter word for that. You are a fool. Hey, how come? You know that every word you say is being heard by the commander up there in the central control section. Why do you persist in talking? Because this gets my goat. I'll skip it. I know it's slang, but when I'm excited, I have to think in slang to get anything done. All this mysterious stuff. Here we are in a submarine a hundred feet long with a crew of one man and a beautiful girl in command. So you do think she's beautiful, do you? Well, I've got good eyes. Even if she is a Euclidean, she's a peach. A peach? Jerry, she is not a peach. Enough of this ridiculous discussion. Silence, both of you. I wish the communication channels clear. I'm sorry, Commander. Okay. Now, Jerry, you must sit quietly and say nothing more until given permission. I warned you that our conversation could be heard all over the boat. And is all that really coming from a submarine G-47? Precisely. We could hear them as plainly as if they were in this room. Yet they weren't deliberately using a microphone. Ah, an Euclidean. We have ways of hearing anything we wish to hear. Yes, I believe it. Well, as long as that girl skipper won't let the kids talk, there's nothing of interest for us to hear. Let's go back to the art path. Yes, even though it's helpless in a lark under 50 feet of water, I feel more comfortable there than here. Well, thanks for the show, G-47. Will you excuse us now? No, I will not. Come here. I want you to observe something. You mean looking at that prism reflector on your desk? Precisely. What's the use, Tex? You were fooled once by that thing. So I might see something anyway. Let's have a look. I will enlarge this image for you. You will be interested in seeing the interior of the submarine from which you just heard. Look. Look. Why, Tex, it's the inside of a submarine. Don't get excited, Pat. We're eight fathoms below the water level. So is the sub. And they're miles from here. Now, don't let it fool you. But, Tex, look, Jerry and Joan inside the submarine. It's as clear as a photograph of them. Yeah? Well, maybe this look is on a level. Yes, sir, look. You can even see the expressions on their faces. Jerry doesn't look any too happy, does he? You heard that woman, Commander, tell him to be quiet. That's quite a punishment for Jerry. Commander seems to be busy with the controls. I wonder what's going on. Ah, silence. The Commander is about to communicate with me. May we watch the image while you do your stuff? You may. And you will notice the clarity of objects within the submarine. The perfection of the voice reception here. The television engineers in your world are hopelessly behind you, Lydia. Watch this, Pat. We're really seeing things now. Commander S1 reporting to G47. 20 miles off Euclidia. Course due north. 25 knots. S1. Your progress and course satisfactory, S1. Report on position of battleships near you. Gee whiz, I heard G47. Yes, Jerry, of course. Did you get that, Pat? The kids are hearing G47. Hey, Joan, I heard Captain Bradford. Yes, the captain must be in the communication chamber. And my mother also. Yes, Joan. Mother can hear you, dear. Oh, Jerry, did you hear my mother? Commander, you will take steps to secure silence on board. Correct, G47. I will have silence. Look out, Joan. She's going to use a ray gun. It would be useless to try to avoid it, Jerry. Say, if she hurts those kids... Oh, Tex. Silence. Tex, look at the reflector. Jerry has fallen to the floor of the submarine. I can hear you, Mother. Do not fear for us. We will be... Now, there's no reason for what she's doing to those kids. Silence. There is silence on my command now, G47. We'll report on battle fleet. 12 major units are taking part in maneuvers. Four heavy cruisers doing long-range fire. Four destroyers acting as enemy scouts.
