Cast & Crew
After the lights go out during surgery, a surgeon is found dead on the operating room floor with a scalpel in his back. Detective Mack Spencer of the police department arrives to investigate the case. Among Spencer's suspects is Dr. Bob Clayton, a young surgeon. Yet another murder attempt occurs when a hospital attendant stumbles upon the killer, who blinds him with acid. Clayton operates to restore the attendant's eyesight by transplanting the cornea from one of the dead man's eyes. The operation is a success, and the attendant, his sight restored, identifies nurse Lila Haines, who had been spurned by the dead surgeon, as his assailant.
The working title of this film was Murder in the Surgery. A news item in Daily Variety credits Edmund Hartmann with screenplay, but his participation in the final film has not been confirmed.
