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.
