This is the story of the liberation of the German Concentration Camps. Using remarkable archive footage and testimony from both survivors and liberators, it tells of the efforts made to document the almost unbelievable scenes that the Allies encountered on liberation. The film explores how a team of top filmmakers, including Sidney Bernstein, Richard Crossman and Alfred Hitchcock, came together to make a film to provide undeniable evidence of what the Allies found, but the film was stopped in its tracks by the British Government and only now 70 years on, has it been completed. Each new generation deserves access to this evidence. Night Will Fall not only uses archive film, it shows the fundamental importance of film as witness to history and the crucial role it plays in the understanding of humanity.
