Comedy in which a minor car accident sparks off a full-scale war between two rival salesmen. Bill Babowsky is a successful bachelor. Ernest Tilley is a dissatisfied husband in trouble with his taxes. Both are 'tin men' - men who con the residents of Baltimore into buying expensive aluminium siding. The feuding pair lock horns after crashing Cadillacs, the prized status symbol of all tin men, leading them to the courtroom.
