SPIEGEL TV documents the history of Nazi criminals who organized death camps and deportations, committed war crimes and mass murder, and never showed remorse, with rare and in part previously unpublished archive material, footage of locations and selected interview partners. Author Michael Kloft also met and questioned Katrin Himmler, the grandniece of the "Reichsführer SS". Finally, he accompanied one of Himmler's victims, Lucille Eichengreen, to the sites of her martyrdom in the former ghetto of Lodz and the Bergen-Belsen concentration camp. Heinrich Himmler organized the brutal persecution of political opponents in a system of concentration camps for his Führer. The fanatical National Socialist and anti-Semite planned the annihilation of the European Jews. In the end, more than six million people were murdered in the Holocaust. The documentary tells the story of the Nazi criminals who organized death camps and deportations, committed war crimes and mass murders and never showed remorse.
