Stan Grayson, a New Orleans big-band clarinetist, endures a haunting nightmare: a mirrored room where he seems to kill a man, underscored by a dirge-like soundtrack that lingers even as he wakes. He finds blood on his skin, bruises circling his neck, and a mysterious key from the dream still clenched in his hand. The image is hard to shake, casting a pall over his days and nights and coloring his sense of reality with doubt.
He confides in his brother-in-law, Rene Bressard, a police detective, only to be dismissed as overwhelmed by nerves. The tension between dream and contagion of guilt widens when the two men later head out for a country picnic with Grayson’s girlfriend, Gina, and his sister, Madge Novick. Grayson leads them to the empty house from his vision, and dark rain begins to fall as they explore. They locate a record player and begin to dance; a nudge from Gina sends the phonograph into an altered speed, the tempo slowing until it matches the very melody from Grayson’s nightmare. The house reveals a mirrored room, precisely as in his dream, and they confront the undeniable fact that a murder did occur there. Disturbingly, Bressard’s suspicions turn toward Grayson himself.
Grayson, increasingly tense and on the brink of despair, protests his innocence even as the circumstances tighten around him. This forceful stance pushes Bressard to dig deeper, driven by a need to separate truth from fear. The trail leads to a hypnotist living in Grayson’s building, a figure who may have unlocked a dangerous control over him. With this possibility, Bressard faces a pivotal challenge: to prove that the murder was committed by Grayson not of his own free will, but under an influence that overpowered his agency.
