In Los Angeles in November 2019, expolice officer Rick Deckard Harrison Ford is detained by officer Gaff Edward James Olmos and brought to his former supervisor, Bryant M. Emmet Walsh. Deckard, whose job as a Blade Runner was to track down bioengineered beings known as replicants and retire a euphemism for killing them, is informed that four have come to Earth illegally. As Tyrell Corporation Nexus6 models, they have only a fouryear lifespan and may have come to Earth to try to extend their lives.Deckard watches a video of a Blade Runner named Holden administering the VoightKampff test designed to distinguish replicants from humans based on their emotional response to questions. The test subject, Leon Brion James, shoots Holden after Holden asks about Leons mother. Bryant wants Deckard to retire Leon and the other three replicants Roy Batty Rutger Hauer, Zhora Joanna Cassidy, and Pris Daryl Hannah. Deckard initially refuses, but after Bryant ambiguously threatens him, he reluctantly agrees. ........
