Through previously undiscovered private letters, photos and diaries that were found in the Himmler family house in 1945, this documentary exposes a unique and at times uncomfortable access to the life and mind of the merciless 'architect of the Final Solution', Heinrich Himmler. Himmler writes, 'In life one must always be decent, courageous and kind-hearted'. How can a man be a hero in his own eyes and a mass murderer in the eyes of the world?The text of the film consists exclusively of original documents from Himmler's lifetime, combined with news and personal archive from sources ranging from the descendants of top Nazis to working-class individuals. It forms a unique portrait of one the most prominent figures of the Third Reich, the SS commander Heinrich Himmler.
