After the events shown in the movie, Deckard has retired to an isolated shack outside the city. He has stolen the replicant Rachael in a Tyrell transport container, which slows down the replicant aging process to prevent lengthy transportation counting against their four-year lifespan, only releasing her for brief intervals. Deckard is approached by a woman identical to Rachael, who explains she is Sarah Tyrell, human niece of Eldon Tyrell, heiress to the entire Tyrell Corporation and the human template (templant) for the Rachael replicant.
