Classic Doctor Who: Resurrection of the Daleks

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'.

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.

The Daleks reveal their plan of cloning the Doctor and his companions and using the clones to assassinate the High Council of Time Lords on Gallifrey. Back in London, Tegan tries to escape by running east down the Thames Path, pursued by Lytton's policemen.

As survivors of the prison station fight the invaders, Davros dispatches his newly Imperial Daleks and loyal troopers to Earth. Anticipating resistance from the now Renegade Daleks led by the Supreme Dalek.
