Year 2019, the city of Los Angeles is a dark and decadent place, an abyss dominated by huge skyscrapers and large neon signs. Rick Deckard (Harrison Ford) is a blade runner, a police officer for the removal of illegal replicators. Its mission is to hunt down a group of four of these androids, sophisticated NEXUS 6 superior in strength and intelligence to humans, but designed to live a short existence of four years. This group, which has fled from a space colony and entered the Earth with unknown intentions, is led by the especially dangerous and intelligent Roy Batty (Rutger Hauer).
Deckard’s research will take you to the powerful Tyrell Corporation, a robotics company headed by millionaire Eldon Tyrell (Joe Turkel). There Deckard will meet Rachel (Sean Young), the beautiful secretary of Tyrell who does not know her own replicating nature. Despite his prejudices against these beings, Deckard will not be able to avoid being attracted to the young woman, so he will begin to question the honorability of his work and to consider transcendental conflicts about humanity that these creatures may have that the only thing they crave is power live longer than man has awarded them.
