Frank and Madge Hammond are celebrating their first wedding anniversary. The couple next door, Tom and Lois Fraser, have been married a lot longer and are constantly battling about Tom's roving eye. Madge cooks a special dinner in honor of their anniversary, but at the last minute, Frank, a salesman, calls to explain that he must attend a business dinner. His client is Bunny Fitch, whose husband, Colonel J. Kingsley Fitch, is out of town. Bunny is not as interested in buying a boat as she is in the way Frank looks. While he is doing his best to fend off her advances, Tom knocks on Bunny's door. Assuming Tom to be her husband, she chases Frank out the window without his brand new overcoat--a present from Madge. Then when the colonel unexpectedly returns, Tom follows Frank out the window, minus his overcoat. To Bunny's dismay, the colonel has brought his pet sheep "Eloise" with him. When the colonel notices the two overcoats, Bunny tries to convince him that they are his coats, even though they clearly do not fit him. At home, Frank tells Madge that he gave his coat to a beggar. Madge does not completely believe him, and when she overhears Bunny telling the story at the beauty parlor, she decides to divorce him. On the train to Reno, she meets Lois, who also plans to get a divorce. Traveling on the same train are Bunny, the colonel and Eloise. Frank and Tom follow on the next train; Frank at least intends to stop his divorce. In Reno, Tom pretends to be the beggar that received Frank's coat, and Madge is about to cancel her divorce when Lois walks in and recognizes him. Madge changes her mind again when Frank begs her not to divorce him. The two couples attend a party given by Bunny and the colonel. When everyone decides to leave for a nightclub, the colonel offers Tom and Frank their old coats. Lois, Mabel and the colonel become infuriated when they recognize the coats. Later, Tom, Frank and Bunny decide to demonstrate just how easily someone can appear guilty. They trick the women into the colonel's room and knock on the door. Facing difficult explanations, the two women hide and Tom throws their fur coats out the window. After confused explanations, everyone is reconciled.
