Davros has awoken from his centuries long slumber and is taken prisoner by the Doctor before the Daleks can reach him. But the Daleks will stop at nothing to recover their creator.
Romana is captured and interrogated by the Daleks whilst the Doctor meets the Movellans who are equally interested in discovering exactly what the Daleks are searching for.
The Doctor discovers that the Daleks need Davros to break the stalemate in their war with the Movellans, and the Movellans now want the Doctor to fulfil the same purpose for them.
