"Who are you? You don't know. Then you come into the field of interest, and that tells you who you are." Golo Thomsen - SS officer with the best connections to Berlin - works in the "Interessengebiet Auschwitz", the largest extermination camp during the National Socialist era. Against the backdrop of the most unromantic place of the 20th century, Thomsen loses his heart to Hannah Doll, the camp commander's wife, and submits to his audacious obsession, even if he cannot foresee the consequences of his quest.
