In the most personal and unflinching film of his career, historian Simon Schama confronts the enormity of the Holocaust and the catastrophe experienced by its victims. In a journey that ends with his first visit to Auschwitz, Simon travels across Europe to explore how the Holocaust was far more than a Nazi obsession that played out in gas chambers, but a European-wide crime of complicity. From bullets in the Lithuanian lands of his ancestors to bureaucracy in the Netherlands, he reveals how deep-rooted prejudice was weaponised to turn people against their Jewish neighbours. As a moving interview with a survivor reveals, the story of how ‘evil comes step by step’ remains powerfully relevant today.
