Musician Eduard Boeckel wants to settle down and marries laundry owner Lisbeth Timm. He brings his friend August Garfs into the marriage, and the housekeeper Alwine quickly sets her sights on him. In his new position, Boeckel invents a laundry detergent with unfortunately disastrous consequences: the laundry becomes brittle, and the first major marital spat ensues. Eduard flees to his fellow musicians, gets drunk, and seeks solace with Alwine. When she drives him away, he returns contritely to his wife, who forgives him. And now she also knows what is truly wrong with their marriage: her Eduard misses his profession. From now on, he makes music, and she does the laundry.
