Vienna, in the 1920s. Fanny Hobichler can dance, sing and act. She really wants to go to the theater, but so far she has not had a chance to prove her talent. Again and again someone with less talent snatches an interesting role from under her nose. When the capricious singer Serena Villon does not want to appear on stage after an argument with her lover, Fanny's big moment has come: she is finally allowed to play the theater and sing too! In order to make it big, Fanny absolutely wants to audition for the theater director Jason, who is, however, screened because otherwise some young talent would constantly besiege him.
