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. Those who escaped and returned to Earth were hunted by Blade Runner units - with orders to kill any trespassing Replicant upon detection.In 2022, a Replicant attack on the Tyrell Corporation forced the company into bankruptcy and erased all records of existing Replicants. The surviving Nexus 8 models disappeared with the help of the Replicant Underground. Many Replicants remained in servitude.In 2027, Aahna "e;Ash"e; Ashina, a former Blade Runner, rejoined the department to hunt down fugitive Replicants. Her superiors are unaware that her loyalties are divided. Her lover, Freysa, is a leader in the Replicant Underground.Now, a new case leads Ash to believe that a Nexus 6 Replicant, who evaded capture years ago, is still alive, long after his lifespan should have expired.Los Angeles, 2029.
