On the advice of his chief counsel Julius, old Lord Gundolf offers the throne to whichever of his sons brings him the finest carpet. He blows three feathers into the air for the boys to follow. The eldest brothers Gerhard and Gebhard are sure they'll win the contest. One goes east and the other goes west. Both make fun of the youngest, Gustav, whom they call "Simpleton", because his feather flies into a forest.

After several strokes of fate ends a rage eruption of the otherwise so quiet power engineering technician Felix Grünler with a criminal complaint for assault. A grateful affair for his sister-in-law Karin, who forges an intrigue to gain the inheritance of her mother-in-law. She succeeds in having Felix admitted to psychiatry as incompetent. He is determined not to get into therapy. For doctors, this confirms the picture of the labile patient. But in the other patients Felix gives his consistent anti-attitude in the long run benevolent recognition.
