Naughty Susanne (Ruth Weyher) leads an thrilling double life between her hometown and Paris: In her hometown in the provinces she is seen as the ever virtuous and down-to-earth girl next door, while in the metropolis, to which she regularly escapes, she is the queen of the night, fashionable and seductive, desired by many men. In Paris, she meets René (Willy Fritsch) and begins to court him, but she has an aristocratic rival: Jacqueline (Lilian Harvey). A lively love triangle ensues, complicated by the interventions of uncomprehending finger-wagging do-gooders. The story reaches its fitting finale at the Moulin Rouge.
Based on the popular operetta of the same name by Jean Gilbert, who appears in a cameo in the movie, this musical rom-com mixes French ésprit, the big-city tempo, and the dance-loving spirit of the 1920s with a healthy dash of frivolity. Here, Lilian Harvey and Willy Fritsch, the later dream couple of the UFA talkie era, appear in their first – albeit silent – film together.
