This vital documentary starts slowly, as human rights lawyer Philippe Sands meets two elderly men who recall their contrasting childhoods: one happy, the other miserable. The link? Their fathers were high ranking Nazis. Family photos are shared, reminiscences dwelt on, then Sands takes them to the sites of World War II atrocities, and Niklas Frank damns his dad while Horst von Wächter defends his. Their friendship is tested and their contrasting attitudes shed stark light on how these terrible events came to pass. Sands has his own personal link to the Holocaust, revealed over time, and My Nazi Legacy becomes horribly gripping.
