Ravensbrück, established by Heinrich Himmler in 1939 just north of Berlin, was the Third Reich's only concentration camp built exclusively for women and children. This film traces its history through more than 130,000 prisoners who passed through the nine-square-kilometer complex, among them Jewish families, political dissidents, and members of the French resistance. Survivor testimony, some of it from women recorded in their final years, sits alongside clandestine drawings made inside the camp, sketches smuggled out or hidden that show daily roll calls, forced labor, and the medical experiments conducted on prisoners. The film also covers the camp's female SS guards and the small, dangerous acts of defiance inmates organized against them, from hidden messages to sabotage. The narrative runs through to liberation in 1945, closing a chapter of the war that gets far less attention than the larger camps. The drawings and firsthand accounts carry the film; there is little need for embellishment when the source material speaks for itself.
