Walter, a songwriter who is in love with Mary, a nightclub singer, prefers to make a living by fleecing crackpot songwriters and promoting their creations. When Walter writes "At Last I'm in Love" for Mary, she promises to plug the song at the Frivolity Club, but he leaves in a huff when she flirts with Sam, a legitimate song publisher. On the street, he gives refuge to Claire, a girl accused of a theft, and hires her as his secretary. Mrs. Fioretta gives Walter a large sum to publish her song, "The Night Elmer Died," but Sam induces Mary to get Walter to stop the deal. When Walter discovers that Claire is having an affair with Sam, he returns to Mary at the club. A lost film.
