In order to escape the demands on his time and energy by female admirers, Larry Charters, a popular writer of popular songs, arranges to have his friend Bob Hawley impersonate him. Traveling on the Continent, Bob meets a French actress, Colette, on a train. In France, Bob and Colette are accidentally left behind at a village station, and they go to the mayor to find rooms for the night. Believing that they want to get married, the intoxicated mayor marries Bob to Colette in Larry's name. Bob and Colette later take the train for Paris, where Larry is introduced to his new and unexpected wife. Larry immediately falls in love with Colette and arranges for her to stay with him, but she remains his wife in name only. Bob becomes engaged to Gloria, one of Colette's friends. At a house-party, Collette disguises herself as one of Larry's old girl friends in an attempt to test his love and loyalty. After considerable confusion and misadventure, Colette and Larry perceive their mutual love and make plans actually to be married.
