Ole Olsen and Chic Johnson are Broadway stars who return to Universal Studios to make another movie. The mere mention of Olsen and Johnson's names evacuates the studio and terrorizes the management and personnel. Undaunted, the comedians hire an assistant director and unknown talent, and set out to make their own movie.
