On April 15, 1945, British troops liberated Bergen-Belsen concentration camp on the Lüneburg Heath. A camera crew documented shocking evidence of the crimes committed by the Nazi regime with images of piles of corpses and emaciated inmates. London-based producer Sidney Bernstein planned to use this material alongside other allied footage to make a film that would illustrate the scale of the Nazi's extermination policy and thus provide support for the allies' psychological offensive against Germany. Director Alfred Hitchcock was asked to edit the film. But after the war ended, the occupying forces changed their policy -- instead of confronting the Germans with their guilt, it was considered more important to instill new confidence to meet the challenges of post-was reconstruction. Here, we retrace the story of this unfinished film which for decades was known as "the missing Hitchcock".
