'Sound the Siren and I'll Come to You Comrade'
by John Pritchard
The Doctor and Leela arrive on a barren plain in the Soviet Union of the 1950s. Twisted wreckage and remains speak of the tests of a destructive new power. The scientists responsible live in terror of their political masters.
But now they all have something else to be scared of..
