The Doctor and Clara find themselves dealing with Cold War tensions when the TARDIS lands aboard a disabled Soviet ballistic submarine. The Doctor isn't the only alien being on board however - while engaged in undersea drilling, Professor Grisenko thought he'd found a mammoth and brought the creature on the boat encased in ice. It isn't a mammoth but an Ice Warrior, who has been lying dormant for 5000 years. He identifies himself as Grand Marshal Skaldak but when he cannot contact others of his kind, he assumes he is the last of his race. He now has every intention of starting a thermonuclear war between the superpowers and destroy Earth. Written by

The new Ice Warrior costume was constructed by Neill Gorton
and his team at Millennium FX. While respecting Mark Gatiss
' desire that this should hew as closely as possible to the original Ice Warrior design, Gorton effected some changes to make the armour more credible: the hands had digits rather than clamps, the proportions were better balanced, and the tufts of fur were removed. (In some ways, the overall conception of the new Ice Warrior reflected Brian Hayles' original vision of the Martians as being partly cybernetic.) However, to accommodate such a massive costume - as well as to provide more space for the cast and crew - scenes aboard the Firebird would have to be largely realised in the studio, since a real submarine would be far too cramped.

Textual labels throughout the sub are either meaningless combinations of Cyrillic letters or transliterated English words. This is most evident on the depth indicator, where the Cyrillic letters spell the English word "meters" instead of the Russian "metry". See more
Oh professor, I could kiss you!
