In a dystopian future where Earth's ecosystem has largely collapsed, society depends on bio-engineered humans known as replicants for labor. These replicants are created by the powerful Wallace Corporation, designed to be more compliant than their predecessors. K, a newer-model replicant, works as a "blade runner" for the LAPD, tasked with hunting down and "retiring" rogue older-model replicants. K uncovers a long-buried secret that has the potential to alter society: a replicant has somehow given birth. This revelation leads K on a quest to find the child and uncover its significance, a trail that histories have been scrubbed to hide.

K's investigation leads him to a series of clues and encounters with figures from the past, pressing him to question his own identity and purpose. His search becomes increasingly fraught with danger as powerful forces seek to prevent the truth from emerging. Throughout his journey, K is accompanied by his holographic companion Joi, who provides him with emotional support and companionship. As K delves deeper into the mystery, he discovers connections that tie him to the child's enigmatic origins and to Rick Deckard, a former blade runner who has been missing for 30 years. Deckard's fate intertwines with K's own as they confront the implications of the discovery together.
