Niklas Frank and Horst von Wachter, each of whom are sons of high-ranking Nazi officials, travel throughout Europe—and reflect on their personal histories—with human-rights attorney Philippe Sands, who lost many family members in the Holocaust. Frank has no problem denouncing his father, who was convicted of war crimes at Nuremberg and executed in 1945; von Wachter, however, sticks to a belief that his father was a decent man in a bad situation.
