[The following plot summary is based on the English-language version of this film, Her Wedding Night ; character names refer to that version.] Norma Martin, an American film actress vacationing in Paris, weary of male admirers, leaves with her friend Gloria Marshall for the south of France. On the same train is Larry Charters, a famous composer of popular songs, and his friend, Bob Hawley, Gloria's fiancé; to escape pursuing worshipers, he persuades Bob to exchange identities during the trip. When Norma and Bob are left behind at a station, the mayor mistakes them for two elopers thought to be on the train, and before they know it they are married, Bob still masquerading as Larry. Norma and Bob then arrive at their originally intended destination, and complications ensue when Bertie Bird and Mrs. Marshall take Norma and Larry to be man and wife. In spite of the humorous confusion, they decide to let the marriage remain legal, and Bertie gets to sleep after two nights of farcical madness.
