Early in the 21st Century, the Tyrell Corporation advanced Robot evolution into the Nexus phase - a being virtually identical to a human - known as a Replicant. Replicants were used Off-world as slave labor, in the hazardous exploration and colonization of other planets.
Now, on Earth, the Nexus 4 Replicants have been adapted for societal elites to own for industry and service work. But Tyrell continues to experiment with further enhancements - because progress stops for no man.
After the apparent suicide of Dr. Lydia Kine - a Tyrell Corporation bioengineer - was determined to be a murder committed by a Replicant, LAPD Detective Cal Moreaux is tracking the presumed killer: a Nexus 5 prototype.
The Nexus 5 has been "awakening" some Replicants, causing them to leave their positions of servitude in pursuit of autonomy. Cal has followed this trail of rebellion to Sector-6b, the slums of Los Angeles - a home from which his badge has exiled him - where he learned of the true identity of the escaped Nexus 5... his sister: Nia Moreaux.
