'During a masked party Stephen Kester (Claude Gillingwater) is found dead in the closet of his room, three stab wounds in his back. Suspicion falls on everyone at the party, especially Kester's granddaughter Jean (Shirley Grey) and her fiancé Cliff Miller (William Bakewell), who fled the house after disabling all of the other cars and cutting the phone lines. As Inspector Crofton (John Wray) and Detective Regan (Ben Hendricks Jr.) investigate they are shadowed and helped along by a mystery writer, Bill Tracy (Charles Starrett).'
