"KZ Buchenwald. Aushalten. Wir eilen euch zur Hilfe"

Five Jewish Hungarians, now US citizens, tell their stories: before March 1944, when Nazis began to exterminate Hungarian Jews, months in concentration camps, and visiting childhood homes more than 50 years later. An historian, a Sonderkommando, a doctor who experimented on Auschwitz prisoners, and US soldiers who were part of the liberation in April 1945.

When Allied forces liberated the Nazi concentration camps in 1944-45, their terrible discoveries were recorded by army and newsreel cameramen, revealing for the first time the full horror of what had happened. Making use of British, Soviet and American footage, the Ministry of Information’s Sidney Bernstein (later founder of Granada Television) aimed to create a documentary that would provide lasting, undeniable evidence of the Nazis’ unspeakable crimes. He commissioned a wealth of British talent, including editor Stewart McAllister, writer and future cabinet minister Richard Crossman – and, as treatment advisor, his friend Alfred Hitchcock. Yet, despite initial support from the British and US Governments, the film was shelved, and only now, 70 years on, has it been restored and completed by Imperial War Museums under its original title "German Concentration Camps Factual Survey".
