The story follows a movie crew who is filming a musical in a small and idyllic alpine village. After their temperamental leading lady drops out of the film, they decide to replace her with the village's young post office clerk Gretl, who returns to Berlin with them. There she has to struggle with the movie's all-male crew, who all try to woo and win her.

The lively Anny meets the nice Dr. Jack Braun and throws everything in his life into disarray. As Jack is in the middle of divorce proceedings against his wife Renate, his lawyer and best friend Richard doesn't like the idea of a female being in his vicinity. Then Jack's heiress Frieda comes to visit, and when she finds Anny in Jack's house, she mistakes her for his wife - and finds her extremely charming. When the aunt's parrot dies, the relatives believe that the aunt has died and rush to claim the inheritance. Anny emerges victorious from all this.
