Dan Moore, who was reared in New York's gas house district, has worked his way up and is now a rich and well-known figure in New York's night life, but is in need of social status. When the distinguised Reggie Van Dorset bounces a check in Dan's club, Dan offers to clear the debt in exchange for an introduction into society. One night at the theater, Dan falls in love with French opera singer Yvonne, who is featured in a revue, and Reggie arranges an introduction. Reggie, however, substitutes Yvonne with her double, Doris "Toots" Malloy, who is in love with a taxi driver named Eddie. On Reggie's orders, Toots discourages Dan and tells all to Yvonne, who remembers that Dan owns the apartment she lives in and ordered her to move because her singing annoyed him. To get back at Dan, Yvonne decides to keep her own appointments with him, but instead of exacting revenge, she falls in love with him. Eddie, believing Toots is betraying him, becomes jealous, and in the middle of a party at Dan's club, Eddie accuses Dan of stealing his girl, then exposes Reggie's plot. When Yvonne reneges on her promise to perform at the party, Dan gets suspicious, but she later reveals her identity and sings a love song to Dan himself. Toots and Eddie then marry.
