Philip K. Dick's cult sci-fi novel inspired the film Blade Runner. Set in a world devastated by nuclear war, a San Francisco bounty hunter is on a mission to retire a group of rogue androids. James Purefoy and Jessica Raine star in this new adaptation.
In post-war 1992 androids are becoming indistinguishable from human beings, even in their capacity to love, and bounty hunter Rick Deckard is tasked with locating and retiring a rogue group of escaped androids who have fled a life of slavery and returned to Earth.
