 This documentary stems from 1945, when infantryman Sam Fuller, as a member of the U.S. Army s "Big Red One," helped liberate the Nazis  Falkenau death camp. Fuller shot footage of his commanding officer s marching Czech locals, who denied knowing of the camp, out from town to view the horrors of the camp. 40 years later, French documentary filmmaker Emil Weiss brought Fuller, who became a famous film director after World War II, back to the death camp to tell the story of the camp s liberation. Fuller s footage is incorporated in the film.
