On the trail of a serial killer, Adam, a hardened but admired cop, miraculously survives after being shot in the head. The only lasting effect is that he suffers from amnesia. While recovering, he tries to find out who he is and who tried to kill him. When he discovers a young woman tied up and terrified in his basement, Adam is faced with the most terrifying doubt: what if the killer he was hunting was none other than himself?

Plunged into a nightmare of memories and mounting evidence, Adam pieces together his lost identity amid suspicions that blur the line between hunter and hunted. This psychological descent forces Adam to confront whether his survival instinct will lead to truth or unleash a monster he never knew existed.
