The young ruler of the lands of Regenplatz, Landgrave Heinrich, must marry a girl equal to him in status. But his heart belongs to someone else - a simple city woman. However, the lovers are not destined to be together: Henry’s beloved dies at the hands of robbers. In memory of her remains baby Berkhard - a bastard who, by the will of his father, will have to take his throne. But Henry’s legitimate son, Gustav, grows up with the idea that Berchard is taking everything from him: his title, lands, his father’s respect, and later his beloved Gretta. Hatred for his brother pushes Gustav to commit a crime. Will anyone dare to stop him? Or anything?
