Synopsis:
The Doctor has used a phial of ammonium sulphide to overpower Zondal. As the Ice Warrior collapses he is able to activate the firing mechanism of the sonic cannon...
He and Victoria are unable to stop the weapon striking the Ioniser base. The blast destroys part of the building and causes panic amongst the personnel.
Varga appears on a monitor in the control room, demanding surrender. Sergeant Walters urges Clent to comply, and the Leader reluctantly agrees.
Clent states that no hostile action will be taken against them. He believes he can negotiate with the aliens. Miss Garrett advises that they can use the threat of the Ioniser to strike a bargain with them. When Walters begins to panic, she shoots him with a tranquilising gun.
Meanwhile, in the spaceship, the Doctor is able to listen in to what is going on.
Varga and his men enter the control room as Walters wakes up. He raises his weapon and the Ice Warriors shoot him dead. Varga demands that the mercury isotopes which power the Ioniser be handed over to him, the Doctor having told him that the base uses these. Clent tries to argue that they don't hold these, but Varga orders the reactor be closed down so they can take what they need.
Knowing that the base is doomed without power and heat, the Doctor decides to use the sonic cannon against the aliens. He must calibrate it carefully so that it affects the Ice Warriors but won't unduly harm the humans, reasoning that Martians will have a higher fluid level in their bodies.
Their helmets may also trap the soundwaves and affect them more.
Penley wakes up and slips out of the medical bay. He listens at the door of the control room as Miss Garrett is forced to run the Ioniser down to minimum power. He goes to the environmental controls and turns up the heat and humidity, whilst turning the oxygen level down.
As the heat and humidity rise sharply Varga suspects a trick and orders his men to kill everyone.
The Doctor fires the sonic cannon. The humans throughout the base are stunned but the Ice Warriors are badly affected.
The Doctor calls and threatens to fire again, so Varga and his men flee the base.
He then sabotages the cannon before slipping out of the spaceship with Victoria, who he sends to the safety of the TARDIS.
Zondal has recovered by the time Varga returns to find their cannon wrecked. He orders that they prepare to lift off and free themselves from the glacier before the humans can attack them.
As the base personnel recover, the Doctor and Penley urge Clent to use the Ioniser at full power, risking the potential explosion of the spaceship. Clent and Miss Garrett cannot bring themselves to take action without consulting the computer. It spins out of control and they realise that it simply cannot commit to any action which might mean its own destruction.
Crippled by doubt, Penley overrules them and takes over.
In the spaceship, Varga thinks that they have sufficient power to take off - but it is just the effects of the Ioniser heating the glacier.
As the device reaches full strength, the craft explodes - the blast registering only as a minor explosion on the base monitors.
The crisis over, the Doctor and Jamie slip away unnoticed.
Clent and Penley reconcile, each recognising their own individual strengths and talents but agreeing to work together once more.
Outside, the TARDIS dematerialises...

The final episode of The Ice Warriors did not contain any of the Ealing filming and was produced entirely in studio.
Malcolm Taylor, playing Walters, was not available for the first three rehearsal days and Michael Attwell, who was portraying the Ice Warrior Isbur, stood in for him.
Once again the Warriors' dialogue was pre-recorded (on the Thursday before recording).
Deborah Watling would be unavailable for the evening's studio session, and so it was decided to record her scenes during the afternoon when camera rehearsals would normally be held. The reasons for her absence are unknown. In later interviews even she was unable to recall the circumstances.
The ending of the previous instalment had been transferred to film for use as a reprise at the start of the episode.
Wendy Gifford, playing Miss Garrett, went back to wearing the costume she had worn in the opening instalments.
The VFX team rigged the sonic cannon control panel to explode when the Doctor sabotaged it by touching two wires together. They also rigged the main control panel to explode at the conclusion.
As the television cameras were large and unwieldy, a periscope lens attachment was used to show Walters lying at the feet of the Ice Warriors. The picture was rippled to indicate the rising heat in the base, and later a series of quick jump cuts were employed to show the effects of the sonic cannon on the aliens, with the actors clutching at their heads.
For the destruction of the spaceship, Bernard Bresslaw refused to fall over in his cumbersome costume. As well as the control panel burning, smoke was pumped onto the set and the ripple effect was once again used. The camera was tilted and rotated, and the image eventually whited-out.
The TARDIS departure was a model shot, superimposed onto an arctic scene, making it appear transparent. When last seen it had been lying on its side, but was now upright.
Brian Hayles had suggested that the sound of the TARDIS dematerialisation be played as the camera panned across the faces of Clent, Penley and Miss Garrett.
One small cut was made before transmission - the end of the scene in which Varga reprimanded Zondal for allowing the prisoners to escape and destroy their main weapon. The sub-commander would be punished later but first they must take off before the melting ice flooded their ship.
Following broadcast, a short trailer for The Enemy of the World was shown, comprising the scene in which the Doctor watched a speech by Salamander.
Derek Martinus would later cite The Ice Warriors as his favourite story, mainly due to the calibre of the guest cast he had been able to secure.
One of those actors would write to the regular cast members a few weeks later to say that he was now enjoying working in "proper snow". Peter Barkworth was in Austria filming Where Eagles Dare with Richard Burton and Clint Eastwood. After recording his final Doctor Who episode, he had kept Clent's perspex cane.
Patrick Troughton confided in Watling that he was finding the schedule on Doctor Who stressful, and that he had been experiencing heart palpitations.
Film copies of The Ice Warriors were sold to Australia, Zambia, Hong Kong, Singapore and Gibraltar. The story was also purchased by New Zealand but went un-broadcast thanks to the censors.
It was still being offered abroad in the mid-1970's but the film copies are thought to have been destroyed by 1978. The original video recordings were scheduled to be wiped in July 1969. The final episode was wiped that October.
However, in August 1988 a number of film cans were discovered at Villiers House, which had once been home to BBC Enterprises. These were labelled as containing the second, fourth, fifth and sixth episodes of The Ice Warriors. The can claiming to hold Part Two proved to contain the first instalment.
They were screened at the NFT in London in December 1988, and again in November 1991.
The Ice Warriors had proved to be a popular new monster, and the production team were conscious of the expense of the costumes - so it was only natural that thoughts turned to a follow-up story featuring them. Plans were also being made for further Cyberman adventures and even though Terry Nation was willing to allow the use of the Daleks in the series once more, there was no rush to bring them back. A repeat screening of their last outing would be their only appearance until January 1972.
The Martians themselves have impressed with their look and the distinctive vocalisation introduced by Bernard Bresslaw. The story, however, has been lacking in incident for much of its middle section - as Victor Pemberton had once noted. One of the problems has been the lack of interaction between the Doctor and the monsters for much of the running time.
Martinus is right to praise the quality of the guest cast and Troughton has some great scenes with Barkworth and Peter Sallis.
- The ratings end on a healthy note, though down by half a million on the previous instalment. Mid December would have seen many families out Christmas shopping or attending festive events.
- Radio Times on Thursday 14th December published a letter from schoolgirl J Kirkcaldy, regarding the background to events in this story - namely its claim of a second Ice Age. As you can see Mr Hayles gave an immediate response:
- We are actually in the middle of the fifth Ice Age at present - the Quaternary, which began some 2.5 million years ago. Within this there have been glacial (cold) and interglacial (warm) periods. The previous four Ice Ages were the Huronian, Cryogenian, Andean-Saharan and the late Paleozoic.
- One original Ice Warrior helmet from their debut story survives, recently refurbished by Mike Tucker and auctioned by the Propstore. It's one of the first batch used for the Ealing filming.
- Thursday 14th December saw Troughton appear in the Blue Peter studio, dressed and in character as the Doctor. A quarter of a million entries had been received in the "Design a Monster" competition, and today the winners were going to be shown. They were Karen Dagg's Steel Octopus, Paul Worrall's Hypnotron, and Stephen Thomson's Aqwa Man. The creatures were realised by the BBC costume department and would go on show alongside monster costumes from the series at the upcoming Daily Mail Boys and Girls Exhibition at Olympia. More on this soon.
The press covered the competition winners the following day, including a cartoon of the Hypnotron visiting an optician in the Daily Sketch.
- A young viewer wrote into Junior Points of View on 8th January that they had found the Ice Warriors frightening.
- TV Tornado comic featured Patrick Troughton on its cover in February 1968, with an Ice Warrior lurking in the background. The publication had also featured a double page spread on Doctor Who which included images of the Ice Warriors:
