Josias, Prince of Waldeck and Pyrmont, was no ordinary aristocrat. Cousin to Dutch royalty, he joined Hitler’s SS and rose to power under Himmler. As Higher SS and Police Leader in Weimar, he had supervisory authority over Buchenwald concentration camp, where thousands suffered. Tried at the Buchenwald Trials, he was sentenced to life, later reduced. This film uncovers his journey from noble heir to Nazi criminal—and how privilege shielded him from full justice.
