[Teleport section. Vila materializes]
CALLY:      What's happening down there?
VILA:       I'll tell you later, no time now.
JENNA:      Well, what's all the rush?
VILA:       There's a bomb timed to detonate in under 
        half an hour. We don't even know where it is. 
        Give me a linkup with Orac.

[Control room]
AVON:       We have now used up more than half the time 
        we have available.
BLAKE:      Hm.
CAUDER:     [Enters with Grant] Blake, this is Grant.
GRANT:      Good to meet you. [They shake hands]
BLAKE:      And you. We've been hearing about your strikes 
        against the Federation.
GRANT:      You've been hitting them pretty hard, too. You 
        keep it up, you'll put us out of business.
BLAKE:      [Laughs] That I wouldn't mind.
GRANT:      If it meant breaking the Federation, nor would 
        I. [Sees Avon]
AVON:       Hello, Del. It's been a long time.
GRANT:      I heard you were dead.
AVON:       I heard the same about you. Wishful thinking 
        perhaps.
GRANT:      I'm glad the stories were wrong. I felt cheated. 
        We have some things to settle.
BLAKE:      You two can talk about the old days some other 
        time. Right now we have a problem that's just a 
        little more pressing.
CAUDER:     What's the countdown?
BLAKE:      Four two five.
CAUDER:     It's getting closer.
BLAKE:      Vila's using Liberator's computers to try and 
        decipher the code. It could just give us the 
        location.
AVON:       I have found the circuit plans [Holds up plans. 
        Grant joins him]
GRANT:      Yes, that's the detonator. A nasty one, tricky 
        to disarm.
AVON:       You would have to take out the secondary circuit 
        first, go in under here [Points to plans]
GRANT:      Hmm. Might work. Still, not easy.
[The tunnel door opens and Ralli falls into the room]
BLAKE:      Cauder!
CAUDER:     Ralli!  [They gather around her] Ralli, what 
        happened?
RALLI:      Oh. I don't know. Someone came up behind me and 
        just hit me.
BLAKE:      [To Grant] That's an escape tunnel. Come on. 
        [They leave]
CAUDER:     You'll be all right, Ralli.

[In the tunnel, Blake and Grant find Selson's body]
BLAKE:      He's not long dead.
GRANT:      Get his papers. Where do you think this leads?
BLAKE:      Probably comes out by the rocket silo.
GRANT:      Hmm. Must've been trying to get to the rocket 
        when the roof caved in.
[Blake has retrieved Selson's papers and handed them to Grant]
BLAKE:      Who is he?
GRANT:      Selson, sergeant, security forces.
BLAKE:      Hmm. Have you searched all the Federation dead 
        and wounded?
GRANT:      Most of them.
BLAKE:      Any senior officers?
GRANT:      No.
BLAKE:      He's got to be here somewhere.
GRANT:      Who has?
BLAKE:      I came down to question a man called Provine, 
        a Space Major. I think that he can help us 
        with the whereabouts of Federation's Central 
        Control.
GRANT:      There's no Space Major amongst the prisoners.
BLAKE:      Let me try this on you. The complex is under 
        attack, your men have already penetrated the 
        outer defenses. Provine decides to evacuate, 
        he activates the device, starts down the escape
            tunnel towards the rocket silo. An explosion 
        brings down the roof, and kills this one.
GRANT:      Maybe the other one, too.  He could be buried 
        further in.
BLAKE:      No, somebody survived. He waited his chance, 
        went back to the room. When the girl came in 
        and was alone --
GRANT:      He moved out and hit her. It makes sense.
BLAKE:      THAT was Provine.
GRANT:      If you're right, he could be still wandering 
        around here somewhere.
BLAKE:      Yes, come on.

[Corridor. A rebel and Provine, now in rebel uniform, pass 
each other]

[Control room]
RALLI:      I tell you I saw nothing. The only thing I 
        remember is a man in uniform. I just got a 
        glimpse as I blacked out.
BLAKE:      He's got to be found.
CAUDER:     I'll organize a search party.
BLAKE:      [To Ralli] Come on, you need some rest.
AVON:       That last day, when it was all over, did 
        they hurt her? [Blake passes by with Ralli 
        in background]
GRANT:      They kept her under interrogation for nearly 
        a week. They tried everything but she never 
        broke. If she had spoken, told them what 
        they wanted to know, she'd be alive now.
AVON:       She should have told them. [Unseen by Avon 
        and Grant, Blake listens and watches them 
        from a distance]
GRANT:      She held on because she believed in you. She 
        didn't know that you'd run out and leave her 
        to face it alone.
AVON:       That was not the way it was.
GRANT:      I know exactly how it was. She died under 
        Federation torture. But it was you who 
        killed her.
[Blake's bracelet chimes and Avon and Grant turn toward him. 
Blake speaks into his bracelet while looking at the two of them]
BLAKE:      Blake. Go ahead, Jenna.

[Teleport section]
JENNA:      [Into console]  That's it, we got it, Blake, 
        the exact position of the installation. I'm 
        sending Vila down now.
CALLY:      [Into console]  Blake, co-ordinates are one 
        eleven seven nine, intersect four forty-one.
JENNA:      Stand by, Vila.

[Vila teleports and materializes in corridor, enters control 
room]
BLAKE:      Coordinate one eleven seven nine, intersect 
        four four one.
CAUDER:     Are you sure?
BLAKE:      Orac doesn't make mistakes.
CAUDER:     Then we're finished.
AVON:       What do you mean?
CAUDER:     Well, look at that. [Indicates a small screen 
        which displays a tundra] It's the polar cap, 
        right in the center of the ice zone.
BLAKE:      Then we'll have to get to it.
CAUDER:     But it's four thousand miles away. It can't 
        be done.
AVON:       It can if we use the teleport.
BLAKE:      We can teleport right down to the location.
AVON:       We'll need special equipment, thermal 
        clothing.
BLAKE:      We'll do it. [Starts to call the ship]
AVON:       Wait. Disarming a device is not your field. 
        You finish what we came here for: find Provine.
GRANT:      [To Avon] I'll come with you.
AVON:       No.
GRANT:      I can help.
BLAKE:      Look, I don't know exactly what it is between 
        you, but there's enough danger without letting 
        personal grudges interfere.
GRANT:      That's something we can settle in our own time. 
        Cauder, what matters now is that I can give 
        this man backup. I've worked with timing 
        devices. I know the mechanisms.
BLAKE:      All right, it's your decision, Avon. Do you 
        want him?
AVON:       Give him a bracelet.
BLAKE:      Vila. [To Avon] Just one thing: if that 
        countdown goes below fifty and the device 
        is still primed you will be teleported out. 
        Vila and I will do the same.
AVON:       Understood.
BLAKE:      [Into bracelet] Jenna, Cally, prepare 
        thermal equipment. Stand by to teleport, 
        Avon's coming up. [To Grant] One more thing: 
        if anything happens to Avon, I will come 
        looking for you. [Grant puts on bracelet and 
        stands by Avon] Ready?
AVON:       [Into bracelet] Jenna, take us out of here.

[Teleport section. Avon and Grant materialize]
JENNA:      Is everything all right?
AVON:       Not exactly. I'll tell you about it some other 
        time. This is Del Grant, this is Jenna. [Cally 
        enters with suits] Cally, get me those 
        co-ordinates. [To Grant] Put on one of those, 
        you're going to need it. Jenna, I need some 
        high-temperature lances. [She leaves]

[Escape tunnel]
CAUDER:     Any luck?
BLAKE:      He's alive. I know it. He's here somewhere.
CAUDER:     If he is, my men will find him.
BLAKE:      It's a very large area to search. 
CAUDER:     Yes. What would he do? Where would he go?

[Provine in a corridor]
VETNOR:     Where are you going, soldier?
PROVINE:    Circuit maintenance, sir.
VETNOR:     Has this area been checked?
PROVINE:    I've been right through it, sir. Nothing.
VETNOR:     All right, come with me, we're searching 
        the next level.
PROVINE:    Right, sir.

[Teleport section. Avon and Grant are suited up]
AVON:       You adjust the temperature with this 
        [Points to knob on suit] You all set?
GRANT:      Well, uh... [Looks at gun. Avon gives him 
        one]

[Shot of polar region]

[Avon and Grant materialize in polar installation]
AVON:       All right?
GRANT:      Yeah.
AVON:       Look for the lights.
GRANT:      Here they are. [Switches on lights]
AVON:       Good. [Indicates grates in the wall] Heaters.
GRANT:      I see them. [Moves to switches on other wall]
AVON:       That's better. Now all we have to do is find 
        the device.
GRANT:      Right.
[They search]
GRANT:      There's nothing here.
AVON:       Well, keep looking.  [More searching] Grant.
GRANT:      Yeah?
AVON:       There's a relay cable here. I'm going to 
        follow it. [Grant joins him by the wall] The 
        cable goes down under here so it must be under 
        this section. [He lifts a panel and touches 
        the surface] Solid ice. Get the axe. [Grant 
        hands him the axe and he chips at the ice] 
        It's no good -- we're not going to get into 
        this way.
GRANT:      If we stand here talking, we certainly won't.
AVON:       Get a space heater started. I'll put a lance 
        into it.
GRANT:      There's mercury in that detonator. You burn 
        your way in, you could trigger it.
AVON:       I know, but we don't have time to wait for it 
        to thaw. Get started.

[Control room]
BLAKE:      The rocket. That's the key to it.
CAUDER:     Yes. I have men posted at the silo.
BLAKE:      He may try and get in some other way. Through 
        the launch doors, perhaps. I think I'll take 
        a look.
CAUDER:     Well, you better take somebody with you. There 
        might be Federation guards on the loose. Ralli, 
        find somebody. 
RALLI:      Right.
BLAKE:      [Into bracelet] Blake. Any news from Avon?
JENNA:      [V.O.] They're down safely, that's all we've 
        heard.
BLAKE:      [Into bracelet] Call me if they come through 
        with anything.
JENNA:      [V.O] Confirmed.
RALLI:      Whenever you're ready.
BLAKE:      Thank you. Cauder, if there's still no news 
        from Avon when that countdown goes below 
        fifty, I'm pulling out.
CAUDER:     I understand. To stay with us would be a 
        stupid gesture.
BLAKE:      I can take some of you off with me. 
CAUDER:     No, not for me. I'll stay here till the end. 
        Ralli can go if she likes.
RALLI:      No, I'll stay.
BLAKE:      All right, think about it. There's still time. 
[Leaves, taps the rebel guard on the shoulder to go with him]

[Polar installation. Avon and Grant are wearing visors. Avon 
is apparently inserting the lance into the ice -- lights and 
smoke]
GRANT:      Careful, you'll trigger it. [Avon looks at him 
        and Grant moves off. Avon goes back to work]
AVON:       Done it. Get that table under the light. [Grant 
        does, and also pulls some dangling chains out 
        of the way. There's a rumbling noise] What's 
        happening?
GRANT:      [Looks at the ceiling] The main roof beam's 
        cracked...resting on the ice. If it melts any 
        more, it'll cave in.
AVON:       Give me a hand. 
[They lift the device onto the table. Countdown 202, 201, 200]
GRANT:      Well, while it's ticking we're all right.
AVON:       We're going to have to take out the relays 
        to get at the activator. Get the cutters. 
        [Avon reaches into the device. Grant fetches 
        cutters from tool box. Water is dripping freely 
        from the roof. Grant gives Avon the cutters] 
        Which one is it first? Left, right, or center? 
GRANT:      Center first.
AVON:       Cutters. [Grant passes him the cutters. Avon cuts 
        the center wire] Which next?
GRANT:      Right next. No, no, wait! I'm opposite you now. 
        Left is the next in sequence. Your left.
AVON:       You don't get another guess.
GRANT:      Left. [Avon cuts the left wire] Next bit's 
        straightforward. Do you want me to do it?
AVON:       Go ahead.
GRANT:      Hadn't we better turn the heaters off?
AVON:       It depends which you prefer: being crushed or 
        frozen to death?
