Peter is a talented young composer who has so far not been able to get his revue “Traumschöne Nacht” in a music theatre. Behind the scenes of the “Alhambra”, a Paris music hall, he meets Violetta, a young up-and-coming artist. For her sake, Mr. Maroni, the director of the “Alhambra”, who is in love with Violetta but is rejected by her, has organized a costume party at which the young entertainer appears as a little flower seller. When Peter shows up there too, he believes that Violette is actually selling flowers.

All he wants at the moment is to impose Violette, a pretty young singer whose career he supervises. He has her dressed up as a flower seller. When he meets her, Jean-Pierre, who does not realize that she is in disguise, falls in love with her at first sight.
