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.

The last of the impetuous Varicks, Lady Helen Haden is married to Sir Bruce Haden, a brute who treats her shamefully. She falls in love with Ned Thayer, a young American, but refuses to divorce her husband because of the attendant scandal and disgrace. Sir Bruce gains possession of a love letter written to Ned by Lady Helen and divorces her. Ned goes to Africa, and Lady Helen comes to the United States, where she encounters Rudolph Solomon, an art collector who wants her to become his mistress. The noblewoman at first refuses, but when her money runs out, she agrees to the proposal and attends a party at his home. Ned, who has learned of the divorce, comes looking for Helen and meets her at Solomon's party. Lady Helen is so humiliated and ashamed that she rushes from the house and throws herself in front of an automobile.
