An extraordinary, disturbing film that probed Nazi concentration camps in an exercise of memory, using camera tracking to evoke mood and theme. Actual photographs and film footage in black and white contrast with contemporary color footage of the abandoned camp at Auschwitz, to emphasize the changes between then and now, creating a counterpoint that builds to painful realizations of the horrors of the camps, fifteen years before Marcel Ophuls’s powerful The Sorrow and the Pity.
