Best-selling author and historian Heather Dune Macadam has adapted her acclaimed book, 999, into a powerful documentary that sheds light on a wrenching true story. In March 1942, nearly 1,000 young Slovak Jewish women, mostly teenagers, told by their government that they were embarking on a volunteer work assignment, were instead illegally deported to Auschwitz on what was the first Jewish transport to the Nazi death camp. Rather than strictly focus on the suffering and death experienced by most of the girls, Macadam tells stories of a small group who survived against all odds, even under unimaginable conditions that lasted more than three grueling years.
