Doctor Who and the Day of the Daleks

World peace hangs in the balance. Sir Reginald Styles, a high-ranking diplomat is the only person that stands between mankind and a third and final World War. But a mysterious and savage guerrilla force from the 22nd Century believe Styles is the agent that shaped their terrifying future and therefore must die...

The Doctor and Jo find themselves flung into the guerrillas' world; a brutal dictatorship policed by the merciless and ape-like Ogrons. The Daleks have invaded Earth, enslaved the population and face certain triumph unless the Doctor betrays all he believes in and condones the cold-blooded murder of Styles in an attempt to change the course of history... irrevocably.
