MURDER BY NIGHT

Allan Strong is out jogging one evening when he sees a brutal attack of a woman by a hammer-wielding serial killer. As the woman tries to escape in her car, she crashes into a construction site, and her car explodes. The murder is the third in a series of brutal slayings by the serial killer. The explosion knocks Strong, a wealthy and reclusive restaurant owner, unconscious, and he develops amnesia. As the only witness to the murder, Strong is a person of interest to police investigators. Police psychologist Karen Hicks works with Strong to try to regain his memory, while police detective Lt. Carl Madsen, who is Hicks' ex-husband, disbelieves that Strong is suffering from amnesia. As the movie progresses, Urich starts to wonder if he is the serial killer.

In the final act, the mystery is revealed and all secrets are exposed, resolving the question of the protagonist’s identity and involvement in the murders.

The ending brings all suspicions, doubts, and accusations to a head, answering who the real Claw Hammer Killer is and confronting the protagonist with the truth of his identity. Despite some critical notes about its underwhelming execution, the resolution underscores the film’s central preoccupation with identity and responsibility, leaving viewers to ponder how much of ourselves we truly want to remember.
