TEXT: REVENGE OF THE CYBERMEN BY: GERRY DAVIS AND ROBERT HOLMES Part Four Running time: 23:21 [SCENE_BREAK] LESTER: Harry, don't touch it. Open that buckle and you'll be blown to kingdom come. HARRY: You mean it's booby trapped? LESTER: These buckles can't be opened until the Cybermen beam the release signal. DOCTOR: Harry, were you trying to undo this? HARRY: Well, naturally. DOCTOR: Did you make the rocks fall, Harry? HARRY: Er, well, I suppose I must have done, yes. DOCTOR: Harry Sullivan is an imbecile! [SCENE_BREAK] CYBERMAN: Progression rate has slowed to thirty metres a minute. LEADER: Then the bombs will explode in eleven minutes from now. [SCENE_BREAK] DOCTOR: So where is Sarah? HARRY: I'm not sure, Doctor. When I last saw her, she was trying to get back to the Beacon. DOCTOR: What? HARRY: Yes. You see, we thought you were still up there, and she naturally wanted to warn you about the rocket. Sorry, I can see you're not with me. DOCTOR: Harry, I'm not with you. HARRY: No, you see, it seems that Kellman, er, he's dead, by the way. Kellman was really working for the Vogan people, and he got the other half, the, what do you call them? STEVENSON: Cybermen. HARRY: Cybermen, that's right. Terribly bad on names. Got the Cybermen up on the Beacon so that they'd be sitting ducks for the Vogan's rocket. Only the Vogans haven't finished the rocket yet, so things have gone a bit wrong. DOCTOR: Yes. LESTER: Doctor, we've got about nine minutes. DOCTOR: Listen, listen, listen! Commander, if you were to keep on going towards the centre, you could draw the radar track away from the rest
SUMMARY:
The Doctor, Harry and Lester try to destroy the Cybermen's relay device, while the Vogans prepare to destroy Nerva even though Sarah is still on board.
