Henriette Lange lives only for the theater in Berlin around 1900. Her grandfather, however, has no understanding for this. He is a prompter and knows all about the hustle and bustle of the theater. Her friend, the chorus girl Liesbeth, is heartbroken because the revue star Vera Schreyvogel has his eye on her boyfriend Hans Reuter. But Liesbeth soon consoles herself with someone else, and Mrs. Schreyvogel is quickly forgotten. For Hans Reuter too, because he now loves Henriette. Liesbeth is dismissed without notice because she has fallen out with Mrs. Schreyvogel, and Henriette now has to sing her part. Her dream finally comes true. As she sings blissfully, she sees the Schreyvogel hugging her Hans in the background. She gets stuck in the middle of the song - her career is over! But not with love: she has conquered her Hans forever.
