Actually Mystery Playhouse, hosted by Peter Lorre. A man has such a vivid nightmare of murder that he goes to report it to his brother inlaw, who is a policeman. Vince even has a button that he claims to have torn from his assailant, and a key. How could it be just a dream? Despite the emotion, the cop is too jaded to believe the story.
The teletypes spring into action to report a murder, and Vince is allowed to go along with his brother in law, Cliff. Everything in the nightmare matches the details of the crime scene. Now Cliff turns on him, trying to slap the truth out of him. What a buddy, good thing this is before the days of police brutality laws. Sane heads prevail when the local sheriff helps out with further details of the crime, actually a double murder.
Details of the murder begin to form the background story. Is Vince’s nightmare actually that, or is he experienceing a mental block? Can a hypnotist release him from his amnesia? Or has someone been playing mind games to make Vince think he committed murder? Regardless, the question remains, if it wasn’t Vince, then who?
