Director Ridley Scott's hauntingly prescient vision of the not-too-distant future stars Harrison Ford as Rick Deckard, a retired police assassin, or blade runner. The Los Angeles of 2019 is a dark, polluted, overcrowded dystopia dominated by cloud-piercing buildings and looming neon billboards, the air dense with acid rain and flying traffic. World-weary Deckard has been called out of retirement to liquidate four escaped replicants--genetically derived androids of great strength, intelligence, and nearly-human emotion who serve as slaves and prostitutes in the off-planet colonies. Led by Roy Batty (Rutger Hauer), they've come to Los Angeles to confront their designer, Eldon Tyrell (Joe Turkel), with their unhappiness about the brevity of their four-year life span. In the course of his search, Deckard becomes romantically entwined with Tyrell's lovely assistant, Rachael (Sean Young), and must eventually confront Batty in an unforgettable rain-soaked sequence. A highly influential fusion of the science fiction and noir genres based on the novel DO ANDROIDS DREAM OF ELECTRIC SHEEP.
