While visiting a health studio, Jennifer Downing, the daughter of millionaire P.J. Downing, is kidnapped. Her father turns to a family friend, Eliot Draisen, who is president of the detective agency Crumb & Crumb, to investigate the case. Elliot is initially reluctant to supply P.J. with one of his detectives, because, as it turns out, Elliot himself is the organizer of the kidnapping. But on second thought Eliot offers P.J. the services of Harry Crumb (Candy), the last descendant of the agency's founders. Although Eliot talks up Harry's detecting skills to persuade P.J., he secretly knows that Harry is incompetent and counts on this fact to allow him to slip right through the detective's fingers.
