Newspaper publisher Temple Trask, who answers the "Letters to the Lovelorn" column under the nom-de-plume "Mrs. Carfax," becomes the hit of his college reunion when he revives his female impersonation act. Returning home, Temple meets Billy Wise, another college friend, who wagers one hundred dollars that Temple will not go into a restaurant dressed as a woman. He takes the dare, then sees Helen Scott in the restaurant and, although he is a cynic who does not like women because he knows too much about them, he falls in love. When he notices that Adrian Graw, a crook whom Temple knew when he was a cub reporter, is after Helen's fortune, Temple, impersonating Mrs. Carfax, accompanies Helen and her grandmother, Mrs. Keyes, aboard a steamer to protect them. On the voyage, Helen becomes good friends with Mrs. Carfax and falls in love with Temple. After Mrs. Carfax punches Graw during a struggle for Mrs. Keyes bonds, the police arrest Graw and his accomplice, Rena Varsey. Helen, astonished when Temple removes his wig, falls joyfully into his arms.
