Classic Doctor Who: Destiny Of The Daleks

The Doctor and Romana arrive on a desolate planet, only to find that they are not the only people interested in the remains of an ancient city.

The Movellans try to discover the purpose of the Daleks. The Doctor has a terrible suspicion.

The Doctor's worst fears are realised, but he and Romana are trapped deep underground and the Daleks are moving in for the kill.

The Doctor and Romana face a terrible quandary. How can they defeat the Daleks without unleashing a greater menace?

On the prison station, only Styles, Mercer and two guards are left alive. Disguised in uniforms taken from Lytton's guards, they plan to blow up the station with its self-destruct system. Lytton explains the Daleks lost their war against the Movellans due to the development of a virus that specifically attacks Dalek tissue. They have woken Davros to find a cure. Despite Lytton's reservations, Davros demands he remain on the prison station while working on the virus.

Davros has been kept in suspended animation aboard a prison space station but now the Daleks have come to collect him, aided by Lytton and his fake 'policemen'.
