The Father of a Murderer takes place in a classroom of the Wittelsbach Gymnasium in 1920s Munich over the course of a single Greek lesson. Headmaster Himmler (the father of Heinrich Himmler) enters the classroom, apparently to observe the students' progress. However, he soon takes over the lesson himself. Himmler mercilessly tests the boys, but his real purpose is to teach a political lesson to the German youths, and through them to settle scores with their fathers.
