While working as an 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.

Robert, Peter and Fritz are the best of friends ... and hopelessly broke. But they don't let that stop them and in short order, they end up renting a deserted gas station. With just a little bit of wit and some elan, they'll bring the old girl back to life and all will look rosy ... until all three of them fall in love with the same dame: Gabi, the daughter of the director of a large gasoline firm. Thanks to her, their eternal friendship is really going to be put to the test.
