Fred Moore and Ned Bates have new fall overcoats just alike. For the rest, Moore has a jealous wife, and Bates an engagement ring, which he intends to present to Miss Clara Morrison. Ned meets Clara to take her to the matinee. She gives him her gloves to hold and he puts them in his overcoat pocket. He has forgotten the ring and they stop at the office for it. Ned slips the solitaire into his pocket, and then, it being a warm day, takes off the coat and throws it over his arm. As he passes the door, Moore calls Ned into his office to sign a legal paper. The latter throws down his coat. Moore's overcoat is hanging across a chair. In hurrying off, Ned exchanges the overcoats. After the theater, Ned and Clara discover that the ring and the gloves are not in the overcoat. They notify the police. Moore comes home late that night, after a gay evening at the club. In the morning his wife discovers a pair of white gloves dangling from a pocket of his overcoat. There is an unhappy scene at the breakfast table, and Moore rushes off to the office without his coat. He drops into Ned's office and absent-mindedly helps himself to the identical overcoat. Mrs. Moore threatens divorce over the phone. A call from Clara, who recognizes her gloves, only rouses that lady's jealousy the more. Meanwhile Ned and the detectives, whom he has put on the trail of the lost overcoat, arrive at Moore's house. Moore has returned and is trying in vain to explain. Then the two men find the two coats, just alike, and a light breaks upon four distracted minds.
