no Megacine. 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.
