A blowhard cowboy talks himself into a job as a movie stunt man.

The stooges are sailors working in a ships' tailor shop. When they can't get passes to go ashore, they steal officers uniforms and go to a party with Curly passing himself off as Admiral Taylor and Moe and Larry as his aides. Two spies, one of them a beautiful woman, trick the stooges into stealing a new submarine. The boys turn the table on the spies and capture them. When the real Admiral shows up, Curly's reenacts the capture and accidentally detonates a bomb, blowing them all to kingdom come.

The boys are stowaways on a train box-car filled with furniture bound for Hollywood where they hope to break into movies and become stars. Arriving at the Carnation Pictures Studios. Fuller Rath, the studio general manager, receives a telegram from the home office telling him that a certain "Mr. Smith and his two assistants" will arrive to take over the supervision of the studios. He mistakes the Stooges as the executives and gives them free reign over the studios, where they proceed to disrupt and destroy the production of a romantic drama.

The Stooges are key witnesses at a murder trial. Their friend Gail Tempest, who dances at the Black Bottom cafe where the Stooges are musicians, is accused of killing Kirk Robin.
