Bobby Bowfinger is a shameless wannabe film producer, who is desperate to break into the Hollywood big-time in spite of the fact that he's broke and unconnected. His plans are thwarted when he is unable to land Hollywood's hottest action star, Kit Ramsey for the lead roll in his movie. Undaunted, Bowfinger decides to make the film with Ramsey anyway, except that Kit won't know he's in it. Determined, Bowfinger and his motley crew surreptitiously stalk their unwitting star through the streets of Los Angeles. They film Kit's every move and trap him in scenes he doesn't know he is in, turning Kit's life into a paranoid nightmare, as Bowfinger's crazy schemes become more and more outrageous.
