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".

Cameramen and women discuss the craft and art of cinematography and of the "DP" (the director of photography), illustrating their points with clips from 100 films, from Birth of a Nation to Do the Right Thing. Themes: the DP tells people where to look; changes in movies (the arrival of sound, color, and wide screens) required creative responses from DPs; and, these artisans constantly invent new equipment and try new things, with wonderful results. The narration takes us through the identifiable studio styles of the 30s, the emergence of noir, the New York look, and the impact of Europeans. Citizen Kane, The Conformist, and Gordon Willis get special attention.

Through interviews with current members, people recently returned from prison or facing trial, writers, academics, activists and major players in various "raids," the documentary traces Anonymous’ evolution from merry pranksters to a full-blown movement with a global reach, the most transformative civil disobedience of our time.
