Barry Avrich's gripping new documentary tells the fascinating story of Ben Ferencz -- the last surviving Nuremberg prosecutor and lifelong advocate of "law not war." After witnessing Nazi concentration camps shortly after liberation, Ferencz became lead prosecutor in the Einsatzgruppen case at Nuremberg, which has been called the biggest murder trial in history. He was27 years old and it was his first trial. All 22 Nazi officials tried for murdering over a million peoplewere convicted. Ferencz went on to advocate for restitution for Jewish victims of the Holocaust and later for the establishment of the International Criminal Court. His fight for justice for victims of atrocity crimes continues today.
