Mysterious notes were unearthed near the ruins of the crematoriums at the Auschwitz concentration camp, the site of the mass extermination of Jews during World War II. Deciphered using cutting-edge digital technology, it was discovered the notes were written by Jews who were part of a special unit called the Sonderkommando, which assisted the Nazis in guiding fellow Jews to the gas chambers and cremating their corpses. These prisoners were deemed "traitors" amidst the shadows of the largest mass extermination program in human history. What took place within the inferno? More than 7 decades later, this disturbing, tragic reality is brought to light.
