Bei Dir war es immer so schön (1954)

While working as accountant in his uncle's factory, talented young pianist Peter dreams of becoming a famous composer. When he shows his work to a producer, he manages to convince him to give him a chance. From time to time he gets bigger contracts that keep him more and more away from home and his young wife Elisa. When he "discovers" and supports a pretty ballerina in Munich, a rumor starts that he's having an affair. He fails to realize that his marriage is threatened.
