The story involves various misunderstandings and entanglements that occur between two married couples, the Browns (Glenn Tryon & Vivien Oakland) and the Dazzles (Tyler Brooke & Anita Garvin). The two couples have apartments across the hall from one another, and all four plan to attend a costume ball together. But after each husband expresses unhappiness with his wife's costume the women angrily refuse to go to the party. The two husbands decide to go "stag" and pick up dates, but when Mrs. Brown changes her mind about attending, and Mr. Dazzle and Mr. Brown switch costumes, mix-ups result.
Mabel plays an out-and-out crook, a "Girl Bandit," no less. And she quickly hooks up with a male partner in crime, in this case a Gentleman Crook played by perpetually grinning Creighton Hale. Mabel seems a little livelier in this film than in some of her other late works. In the very first scene we find her hitch-hiking, and she's forced to make a mad dash for cover when Hale's car nearly hits her. Soon they team up and crash a swanky party in a mansion to steal a jewel from the host's safe.
