Tommy Fawkes (Oliver Platt) is a struggling stand-up comedian who has tried for years to get out from under the shadow of his father, George Fawkes (Jerry Lewis), himself a famous humorist. Tommy finally scores a showcase spot at a major resort in Las Vegas, but when opening night rolls around, Tommy's act is an unqualified disaster, with the failure made even more painful by his father's presence in the audience. In search of a fresh start, Tommy heads to Blackpool, England, where he was born and raised, to look for a new act. Hoping to buy material from local performers, Tommy auditions a large number of acts, most of whom are utterly hopeless, until he sees a hilarious vaudeville team, the Parker Brothers. Their act seems more than a bit familiar, however, and Tommy soon realizes that they're doing his father's old material.
