Following the mind-staggering nuclear explosion which has sent the moon and its research station, Alpha deep into space, Commander Koenig and his dedicated group of scientists have kept the base going and survived crisis after crisis.

Now they find a planet suitable for human life and send a party down to investigate. But the planet has long since been taken over by a group of super androids, and Commander Koenig and his party are in danger both from them and the few humanoids who have survived conquest.

Released in the U.K. and in the U.S. in 1976.
