The year is 2254, calculated in Earth terms, and on the planet Skaro Davros and the Emperor Dalek addresses the battle command of Daleks. Davros tells the Daleks that over the past 100 years they have witnessed the human race advance their scientific knowledge to the point of the humans becoming a threat to the Daleks, and tells them it is time to rectify this problem.

The Daleks travel to Earth to exterminate the human, destroying buildings and bridges at the same time. The Doctor tells Ace that they must destroy the Dalek pods and reverse the death rays before Davros turns Earth into a Dalek production planet.
