'Red Lilac' is a family saga that reflects the history of the twentieth century. It is said that God punishes to the seventh generation. The local NS group leader Goldberger must leave the village and his farm; he cannot stay. He has incurred guilt. The reason for his departure will remain his secret, and he remains silent about it. When he returns from the war, he hands over the responsibility for the new farm to his son, with whom he himself never knew what to do. Only his son Paul will free himself from the family's silent oppression and go to Bolivia. Reinhard Kaiser-Mühlecker writes a grand novel about a guilt that transcends generations and destroys the family.
