Based on the best-selling book, this documentary reveals the little-known story of the 999 unmarried, young Jewish women who were among the first to arrive at Auschwitz. Filmmaker and historian Heather Dune Macadam offers a powerful picture of history as told by the women at the heart of it. Blending interviews, animation, photographs and archival footage, the film shifts between the clinical statistics of the Nazi bureaucratic machine and the heartbreaking testimonies of the survivors. The result is a riveting documentary that captures both the barbarity of the Nazis and the humanity of the brave individuals who suffered under them.
