New Orleans big-band clarinetist Stan Grayson experiences a nightmare in which he sees himself killing a man in a mirrored room, while in the background haunting dirge-like music plays. He awakens to find blood on himself, bruises on his neck and a key from the dream in his hand.
Grayson tells his brother-in-law, police detective Rene Bressard, about the problem but is dismissed. Later, the two men take a picnic in the country with Grayson's girlfriend and sister. Grayson leads them to the empty house from his dream, and it begins to rain. After they find a record player and begin dancing, Grayson's girlfriend bumps into the phonograph, changing the speed. The slowed music becomes the song from Grayson's nightmare. They then discover that the house contains a mirrored room as in Grayson's dream. When he finds that a murder did indeed take place, Bressard suspects Grayson.
Grayson, stressed and suicidal, protests his innocence, which makes Bressard dig deeper. They learn that a hypnotist living in Grayson's building may have caused him to commit the murder. Bressard now must prove that although Grayson committed the murder, he was acting against his will.
