A price war has erupted and the ‘gentleman’s agreement’ between Daley Motors and the former owner of a nearby car dealership is violated after moneylender Don Gedley takes over. Arthur attempts to increase business by radio advertising, but can only afford to use amateur announcers on a local pirate radio station. Grant Gedley, a thrusting young executive determined to prove himself to his father, tries to sabotage Arthur by setting him up with police on hit-and-run charges. Anxious to keep the peace and equally anxious to keep his son out of trouble, Don proposes that Arthur pleads guilty to all charges, in return for paying his fine. But Grant won’t cooperate and violence is the result.
