Plot
A crook steals a bike from a time-traveler that has come from the year 1992, forty years in the future. He robs a bank and pedals into the future but is recognized anyway and shot as he attempts to flee. His body is deposited in 1952 minus the bike and the police wonder which one of them got him because the wound on the dead man's forehead does not appear to have been made by a .38.
