Radiation nil, oxygen normal, pressure normal…an earth reading! The TARDIS has landed in London. A menacing deserted London, with no sign of life and no sense of normality, but the decaying city is not as empty as it seems.

The year is 2164 and the travellers soon find themselves facing antagonists whom they thought they had destroyed…the Daleks. They have conquered the earth. Ten years after a cosmic storm, continents of people were wiped out by a plague. Then the Daleks came in saucers, shipping humans to vast mining areas, turning them into Robomen and against their fellow humans.

Earth contains something no other planet contains-a magnetic core-but why are the Daleks digging for it and how can the Doctor prevent them from tampering with the forces of creation?
