Black Angel is a 1946 black-and-white film noir based on the novel by Cornell Woolrich. Directed by Roy William Neill who directed many of the famous Sherlock Holmes film series. This would be his last film.

Kirk Bennett is falsely sentenced to death for killing blackmailer Mavis Marlowe, ex-wife of nice-guy drunk Martin Blair. Bennett's stand-up wife Catherine tries to prove him innocent, enlisting the aid of Blair, who falls in love with her. Bennett's execution draws near as the two pose as piano player and singer, trying to get the goods on sleazy nightclub owner Marko, a prime suspect. Failing to nail Marko, Catherine goes off to meet with her husband, scheduled to die the next morning, and Blair slips into an alcoholic stupor before the real killer is revealed.

In Los Angeles, when the singer Mavis Marlowe (Constance Dowling) is found dead in her apartment, Kirk Bennett (John Phillips) is accused for the murder, since he had been blackmailed by the victim. Kirk's wife Catherine Bennett (June Vincent) believes her husband is innocent and joins to Martin Blair (Dan Duryea), the alcoholic former husband of Mavis, to investigate the crime and try to find the killer. They suspect of Marko (Peter Lorre), the owner of a night-club that was seen in Mavis' place in the night she was murdered, and they try to prove his possible guilty.
