Titre original : The Man in Hiding
A nicely dressed man hitches a ride with a man on his way to take up a post at an exclusive Chicago boys' school. The hitch-hiker has just been released from prison and is the black sheep of a distinguished family. He kills the driver and takes his place, later using the school as a cover for robbing banks. Can Frank join up all the clues to unmask him?
