And there's no news from cave mouth to we've lost contact with cave mouth to sir
well I want to report small sectors as they come in and get me captain Hawkins sir I've
checked on the ambulance man in the sickbay the discoloration of the skin is fading rapidly
so the doctors antidote seems totally effective so far yes she'd get a move on with that formula
quickly there may be others
I know I'm terribly sorry look what's happening about my call to the Ministry of Defense I'm
sure the doctor won't be much longer well look hurry it up man this is top priority I do realize
all right trouble dr. Meredith is getting very impatient I can't say I blame him give the doctor
a couple more moments I mean he may have run into some kind of problem
it's all right major Walton pull back from gallery four and try to hold them at cave mouth three
over and out the Ministry of Defense miss Shaw I must have that formula all right let's
do it here sir you've got my message with respect sir I don't think you appreciate the
gravity of the situation but there's no time to refer it to the Defense Committee
but where is he I've told you I've no idea read the formula to dr. Crawford he's been hanging on
long enough don't you understand I don't know which is the formula hello dr. Crawford look I'm
afraid I'll have to ring you back there's been yet another delay yes yes yes as soon as I can
Brigadier there was some glass in the lab I don't know sir there's been some kind of a raid
private Upton's dead in the caves no sir here just down the corridor and there's a kind of
scorch mark on the wall stay here miss Hawthorne stay here yes of course
get me dr. Crawford please how many humans have survived the epidemic they will all survive
that is impossible you have discovered a cure yes and soon all the humans will be immune to
your epidemic your plan has failed as your leader wanted it to fail our leader is dead I killed him
I am the leader now thank you dr. Crawford the Silurians have broken in well what about the
doctor well I imagine they've taken him to their base Captain Hawkins send every man we've got into
the caves and I want all civilian personnel evacuated from here immediately sir and organize
a thorough search of that laboratory I'll see to it myself sir you two come with me I give them the
formula to dr. Crawford they're going to make their own tests and then going to mass production
with the antidote well done miss Shaw what are you going to do about the doctor what can I do
try to rescue him you'll have to attack their base at the moment they seem to be attacking us
since the epidemic has failed we must use other means we intend to make this planet uninhabitable
for human beings you can't do that you can't exterminate a whole species is this person ready
for activation all we need now is the power we shall continue to use the electricity of the
humans won't be able to do that thanks to you the humans are no longer making power
that generator has been switched off then you will help us we shall force you to reactivate it
we shall take the center hello hello hello switchboard what's the matter with this thing
the devil we seem to have switched to an emergency lighting system instead this one's dead too and
I've just sent the last of my men into those caves because of the attack I sent every man
I've got down to the caves now the Silerians are cutting our communications what about your
pocket radio now useless at this depth they could break in once to get the doctor they
could break in again exactly only this time it'll be in force
is the machinery prepared I could do nothing without power from the humans generator it
has ceased to function we shall force them to reactivate it when your instruments register
the power you will revive all our people now I shall take the one called the doctor to the
research center I'll go to the ministry myself we need a division down here now see we get it
what's matter with this thing the telephone stopped working now the lift as well Brigadier
look doctor do as he says Brigadier or they'll kill us all we do not need these humans miss
always a scientist if I'm to do what you want I shall need her help the other one is a soldier
he is dangerous kill it you'll have to kill me too you will take us to the nuclear generator
oh we will kill you all I said there was to be no more killing I stay where you are this
center is now in the hands of the Silurians they need the use of the generator now if you follow
carefully the instructions I shall give you your lives may be spared remove the bodies
doctor what do you think you're doing trying to save your lives I keep on the way and keep
what you will now connect this device to the nuclear generator the power source is over here
what is the purpose of this machine that is no concern of yours if I'm to help you I must know
this is the molecular disperser it will convert the energy of the nuclear reactor into microwaves
what purpose the microwaves will disperse the molecules of the filter built which is
enveloped this planet since our time but if this process gets out of hand it will destroy
all life on the planet we can control the process commits work what are they gonna do
destroy the Van Allen belt what the Van Allen belt it surrounds the planet and filters out
some of the Sun's radiation what happens when it's gone it's so hot we will all die of sunburn
on a cloudy day what good will that do them the reptile cold blooded they'll thrive in heat we
shall die it'll be the end of the human race
the generator of the humans is producing power commits the revival process
you will now provide power to operate the de-hybernation machinery and activate the
disperser yes well we'll need to stoke up the reactor miss Shaw I'll need your help
you mustn't tell him the doctor knows what he's doing trust him miss Shaw I want you to feed
uranium into the reactor all right when I tell you lower all the rods in at once doctor Liz I know
what I'm doing please do as I say all technicians your usual sectors please your usual sectors
please all right Liz yes lower in number one rod number one rod check lower in number two rod
number two rod check the sector one increase your power level lower in number three rod
you should be getting enough power now to get your disperser unit into operation
continue to increase the power
No
The reactor is now permanently overloaded.
There's going to be a massive explosion and a colossal radiation leakage.
The whole area will become deadly.
For how long?
For 45, possibly more.
This means nothing to us.
We shall return to our base, waiting hibernation until the radiation has faded.
Kill these humans! No!
They will all stay here to die from the radiation.
Well done, Dr. Fowler.
Well done, Regear.
Perland, you better close down the reactor.
I can't.
You were swallowing nothing.
Well, I exaggerated a bit.
I had to push the reactor past the critical stage or they'd never have believed me.
You better get out of here at once.
We can't.
Why not?
They've jammed the lift. There's no way out.
The re-hibernation mechanism is defective.
One of us must remain.
I am the leader. The responsibility is mine.
The one who remains here will die.
Is sufficient power stored in the hibernation unit?
Yes. I have set the controls to revive us in 50 years from now.
When our people revive, you will be the leader.
See that the apes are destroyed.
Any good now?
No, it's still not working.
Give me time, Liz. Give me time.
Here you are. Try that now.
The water is still rising.
Yes, I know. I'll try fusing the control of the neutron flow.
Now stand well back and cover your eyes.
Well, that seems to have done it.
You are still alive. You tricked us.
I managed to close down the reactor.
Then the others must be revived at once.
At first, I shall kill you.
Well, that's done, Brigadier.
Now then.
And just what do you think you're doing down here?
I'm trying to find out how this hibernation unit works.
I must know if we're going to revive them again.
Revive them?
It's not all at once, you understand.
But one at a time so that we can reason with them.
There's a wealth of scientific knowledge down here, Brigadier.
And I can't wait to get started on it.
I think it's going to be working quite smoothly.
I don't think there'll be any more trouble.
Splendid.
Now, don't forget, Brigadier, nobody is to go into that Silurian base.
Yes, Doctor.
And Miss Shawna will be back as soon as possible with some testing equipment
and probably some other scientists.
Good, good. Well, have a good journey.
Yes.
But don't forget, Brigadier, nobody is to go into that base.
All right?
See you tomorrow.
Goodbye.
Goodbye, Miss Shaw.
Goodbye.
Corporal Nutting.
Sir.
Everything's set up.
Yes, sir.
Give them time to get clear and then set off those explosive charges.
And keep that Silurian base sealed permanently.
Shall I walk back and get some help?
No, no.
This is a minor technical fault.
We'll soon put that right.
Okay.
There you are. That's fixed it.
What's that?
The Brigadier.
He's blown up a Silurian base.
He must have had orders from the Ministry.
What, you knew?
No.
The Governor were frightened.
They just couldn't take the risk.
That's murder.
They were intelligent alien beings.
Our race of them.
Please just wipe them out.
Yeah.
Look who's back.
Whoooooooo!
There's been no radio contact for seven months.
Something's gone badly wrong with Mars Probe 7.
Next Saturday, a new serial begins when Doctor Who meets the ambassadors of Death.
Now we've got to find out who's sending that signal.
Someone is determined to steal the recovery capsule.
People behind this are trying to kidnap the
man who's sending the signal.
The man who's sending the signal is the man who's
sending the signal. People behind this are trying to kidnap Liz Shaw.
I don't know what we brought down in Mars Probe 7, but it certainly wasn't human.
What happens to British astronauts from Mars Probe 7?
A new Doctor Who adventure starts next week.
Doctor Who and the ambassadors of Death.
Back to today on BBC One with the Debbie Reynolds Show.
