A fighter trains for the big bout, and discovers that his opponent is his girlfriend's brother.

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 stooges arrive in Hollywood hoping to make it in the movie business. They sneak into a movie studio where they are mistaken for three new executives who were due to arrive. After taking over production of a movie, causing the director and cast to walk off, Moe takes over as director, with Larry and Curly as the leading man and lady. When the real executives send a telegram explaining why they haven't arrived, the stooges must leave on the run.
