The Novrosk Peninsula: the Soviet naval base has been abandoned, the nuclear submarines are rusting and rotting, 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 even the stone circle on the cliff top.

Starfall is a world on the edge, where crooks and smugglers hide in the gloomy shadows and modern technology refuses to work. And that includes the TARDIS.

On a lonely stretch of Welsh coastline a fisherman is killed by a hideous creature from beneath the waves. When the Doctor and Rose arrive, they discover a village where the children are plagued by nightmares.
