The Hour of 13

Nicholas Revel (Peter Lawford) steals a famous jewel, but when police find a corpse at the crime scene, they start to believe that the person behind the theft also committed several murders. Nicholas isn't a killer, however, and he appeals to Jane Frensham (Dawn Addams), the daughter of a top policeman, for a hand in finding the murderer. As police close in on Nicholas, digging through his apartment for clues linking him to the murders, he gets closer to unmasking the real killer.
