Pretty hat-saleswoman Lola wants nothing more than to become an operetta singer. Unfortunately, it isn't so easy to make it in the music business. Operetta diva Isabella, on the other hand, is sick and tired of performing and leaves the stage, despite the fact that her partner begs her to stay, because without her he can't premiere his latest work on the stage.

Hugo Brinkmeyer, a tax consultant, takes his wife Gerda out to the cabaret one evening. There he encounters a potential client, the wealthy businessman Schwidders. A series of mix-ups lead to Hugo being suspected of both incompetence at his job and being unfaithful to his wife.
