"Once the Doctor is exterminated I shall build a new race of Daleks ... We shall be even more deadly!"

Captured in a Time Corridor, the Doctor and his companions are forced to land on 20th Century Earth, diverted by the Doctor's oldest enemy - the Daleks.

It is here that the true purpose of the Time Corridor becomes apparent: after 90 years of imprisonment, Davros, the ruthless creator of the Daleks, is to be liberated to assist in the resurrection of his army.

But not even the Daleks forsee the poisonous threat presented by their creator. Indeed, who would suspect Davros of wanting to destroy his own Daleks - and why?

Only the Doctor knows the truth. But will he be capable of descending to Davros' level of evil in order to stop him?

Originally transmitted 8 February - 15 February 1984, this two part adventure starring Peter Davison is a welcome addition to BBC Video in this, the programme's 30th Anniversary year.
