Zwei Herzen im Mai.

The musician Peter Paul Müller (Dieter Borsche) lives for his job. So much so that he also forgets the circumstances of the Nazi dictatorship. In the years between 1930 and 1946 he was only allowed to perform in small clubs, but after he met the pretty singer Marion (Vera Molnar), the big breakthrough came. But with the many appearances, the relationship with his wife Annemie (Kristina Söderbaum) threatens to break up.
