Based on actual events, this is the staggeringly powerful story of Auschwitz's 12th Sonderkommando -- one of 13 "special squads" of Jewish prisoners forced by the Nazis to help exterminate fellow Jews in exchange for a few more months of life. Written and directed by Tim Blake Nelson, the film features a first-rate ensemble cast, including Steve Buscemi, Harvey Keitel, David Arquette and Mira Sorvino.
