When the First Union National Bank of Williamstown is robbed, the three bank robbers get away by hitching their car to Wilbur's trailer. When the police find part of Wilbur's coat in front of the open safe, they suspect bank teller Wilbur of being in on the robbery. But according to Carol, Wilbur is not smart enough to rob a bank and it shows. While on the run, they come into contact with Julie, the copper heiress, and make plans to have Wilbur help kidnap her. Of course, Wilbur has no clue as to their true intentions.
