In Fear In The Night, bank teller Vince Grayson (De Forest Kelley) dreams that he kills a man in a mirrored room and hides the body behind a mirrored door. When he wakes he has a key in his pocket and bruises on his body. He visits his brother-in-law, detective Cliff Herlihy (Paul Kelly) who thinks he is under stress and organises a day trip with Lil (Ann Doran) and Betty (Kay Scott). As they picnic, a storm forces them to shelter in a house that contains a mirrored room... Is this a set up? Is Vince a killer?
