Ein Walzer mit Dir (1943)

The composer Hans Helmer can really count his happy blessings: he is married to a wonderful woman, who also happens to be a celebrated operetta star. But Hans is suffering from the success of his wife and is constantly in her shadow. He also doesn't want to profit from her reputation when he tries to get his play, "Husband of the Famous Singer" published. Hans wants to be recognized for his own achievements. So he decides to submit his latest composition under the name of his best friend, the painter Willi Kenter. The director is thrilled with the work, but there are some unforseen complications. Hans' wife Maria hears about the operetta and is likewise very impressed; but also sees through her husband's little deception. She tells him that she is determined to play a part in the performance of the work. That's something Hans wants to prevent at any price.
