Director Richard Anden and his screenwriter take a cruise on a luxury liner, avoiding all feminine attempts to get a movie contract, including the ship singer. When he unexpectedly discovers that a beautiful passenger is involved in a murder mystery and chased by the police he'll try to save her from jail. Yet everyone has a secret in this Austrian musical comedy.

The young ice skating talent, Liesl, lands a part in a new Revue at the Palast Theatre simply because she is confused with someone else. In reality, the roll was to be awarded to Lu Panther, the untalented girlfriend of the theatre's owner, Wildner. After a series of accidents and little disasters, Wildner shuts down the theatre before the Revue can take place. But the Revue's director, Ernst Eder, decides shortly thereafter to present the Revue on an ice skating rink belonging to Liesl's uncle. After a successful run, at first at the Wiener Prater, the performers move on to Spain, Hungary, and a night club with a Jazz orchestra. The Revue becomes a huge success ... and, of course, Ernst and Liesl end up together, too.

In hell, equipped with the latest technological advances, the devils watch the happiness of a Viennese revue singer and her sculptor fiancé on a television screen. Some representatives are sent to Earth to seduce the singer and thus undermine the couple's love, but this soon leads to rebellion among the devilish emissaries, who want to emigrate.
