Doctor Who : The Deviant Strain : Number 4 In The Series :

The Novrosk Peninsula, the Soviet naval base, has been abandoned, and the nuclear submarines are rusting and rotting. Cold, isolated, forgotten until the Russian Special Forces arrive - and discover that the Doctor and his companions are here too. But there is something else in Novrosk. Something that predates everything else, even the stone circle on the cliff top. Something that is at last waking, hunting, killing... Can the Doctor and his friends stay alive long enough to learn the truth? With time running out, they must discover who is really responsible for the Deviant Strain...
