Plot

In Beverly Hills, fashion model Jennifer Downing is kidnapped. Her father, multimillionaire P.J. Downing, turns to family friend Eliot Draisen—president of the Crumb & Crumb private detective agency—to investigate the case, unaware he is the kidnapper. Eliot offers them the aid of Harry Crumb, the last descendant of the agency's distinguished founders. A bumbling, clumsy, but dedicated detective with a penchant for disguises, Harry is recalled from the Tulsa, Oklahoma branch where he was assigned ten years earlier to keep him away from the head office. Eliot believes Harry will be completely ineffective in solving the case.
