Blade Runner: Genetics In L.A.
The Tyrel Corporation is an industrial giant that makes Replicants. Four off-world Replicants, Roy Batty, Leon, Zhora and Pris, comandeer a space ship and return to Earth to see if their lifespans can be increased. Nexus 6 Combat Model Replicants are artificially created through genetic engineering. have a four year life span as a fail safe device, and are not mechanical robots, but rather more like clones. The short life span cannot be lengthened and after Roy kills his maker, he hunts Deckard but saves his life just before he dies. He releases a dove at his death.
Harrison Ford's 'Deckard' character falls for a specially made Replicant named Rachel and at the end of the movie they escape what will surely be attempts to 'retire' her. Unlike L.A., the scenery where they escape to is beautiful with sunshine and moutains in a pristine environment.
