The psychological thriller begins within the suffocating, opulent confines of a secluded countryside mansion, home to the brilliant yet profoundly unstable neuroscientist Dr. Evelyn Vance. Consumed by grief following the sudden, tragic loss of her younger sister in a botched medical trial, Evelyn’s grip on reality has completely fractured. Driven by an obsessive, warped desire to conquer death, she abandons conventional ethics, transforming her basement into a clandestine laboratory dedicated to forbidden neurological experimentation.Evelyn’s solitary existence is disrupted by the arrival of Marcus, a charismatic and ambitious young corporate auditor sent to investigate the sudden depletion of her research foundation's funds. Sensing an immediate threat to her life’s work, Evelyn lures Marcus into her web under the guise of financial transparency, quickly drugging and imprisoning him. Rather than eliminating him, Evelyn fixates on Marcus as the ultimate human subject, believing his peak physical vitality holds the missing biological key to neural regeneration and her sister's resurrection.As the days blur into a harrowing psychological chess match, Marcus fights desperately for survival. He attempts to appeal to Evelyn’s fading remnants of humanity, but his pleas only expose the terrifying depth of her delusions.

Marcus manages to break free from his restraints in the chaos, sabotaging the machinery just as the police swarm the room.
