Synopsis: Germany, 1958. In those years, "Auschwitz" was a word that some people had never heard of, and others wanted to forget as quickly as possible. Against the will of his immediate superior, a young prosecutor Johann Radmann (Alexander Fehling) begins to examine the case of a teacher who has recently been identified as a former Auschwitz guard. Radmann soon lands in a web of repression and denial, but also of idealization. He devotes himself with utmost commitment to his new task and is resolved to find out what really happened. He oversteps boundaries, falls out with friends, colleagues and allies, and is sucked deeper and deeper into a labyrinth of lies and guilt in his search for the truth. But what he ultimately brings to light will change the country forever.
