Destiny of the Daleks, Part Four

With Romana's life at stake, the Doctor must end a centuries-long stalemate between the Daleks and the Movellans. But with both sides going to extreme lengths to trap him, the Doctor must put his trust within the Daleks' prisoners as they plot an attack on the Movellans. As a Dalek battle fleet approaches Skaro, the Doctor realizes he must defeat Davros once and for all - and sets off on a dangerous journey to the ruined Dalek city.
