Early in the 21st Century, the Tyrell Corporation advanced Robot technology 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 to Earth were hunted by Blade Runner units ordered 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 "Ash" 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.While investigating a report of a rogue Replicant, Ash discovered that a Nexus 6 Replicant, Yotun, whom she had failed to retire 12 years previously, had somehow outlived his expiration date and become the leader of a Replicant guerrilla army.Yotun captured Ash and ordered his army to launch an all-out attack upon Los Angeles, and called on all Replicants in the city to revolt against their masters. Then he destroyed the Seawall and took over the LAPD Tower before rigging it for demolition.Rescued from Yotun's clutches by members of the Replicant Underground, Ash raced back to the city to save her lover, whom Yotun had mistakenly believed had joined his cause. Instead, she sabotaged his plan and in retaliation he blinded her in one eye and left her to die in the burning LAPD Tower.Faced with killing Yotun or rescuing Freysa, Ash chose her wounded lover, leaving Yotun to escape.
