In 1945, the Allies liberated ‘death camps’ across Europe. The discoveries were so sickening that the liberators made films of them for the public and for future War Crimes Tribunal hearings. These were not the first filmed evidence of the Holocaust. The Nazis had already killed over a million Jews in the East by shooting.

Newly found footage from the Soviet Union reveals scenes of these killings, as early as 1941. In the 71 years since, they sat in an archive, gathering dust. These unseen films now help us to tell the full, untold story of these killings, taken from a very different perspective.
