The story takes place 30 years after the blackout. The replicant K (Ryan Gosling) is a new generation of blade runner. In today's world, the boundaries between humans and replicants are more clearly defined. Replicants are instilled with the idea of serving humans as soon as they are created, and are absolutely not allowed to have human emotions. One day, the remains of a female replicant were excavated. What shocked Army Lieutenant Josh (Robin Wright) was that this female replicant was not only pregnant, but also gave birth to a child. The existence of this child will completely undermine the rules and order that the government has worked hard to manage. Josh ordered K to find the child and kill him. In an abandoned farm, K found some clues, but these clues were inextricably linked to the memories of the past that he was implanted with. At the same time, the replicant Neander (Jared Leto) and his men Rafe (Sylvia Hoeks) are also looking for the whereabouts of the child.
