Reinhard Heydrich, known as the “Butcher of Prague,” was one of the most feared men in Nazi Germany. As Himmler’s deputy, he commanded the Gestapo and SD, created the Einsatzgruppen, and presided over the Wannsee Conference that set the Holocaust in motion. This film explores his rise to power, his brutal reign in occupied Czechoslovakia, and his dramatic assassination in 1942.
