Auschwitz began as a Nazi labor camp to terrorize the local Polish population and evolved into the site of the largest mass murder ever recorded. Presents an in-depth examination of the camp's evolution and the decisions that enabled such an incomprehensibly inhuman place to come into being. It is the result of three years of research, drawing on the close involvement of world experts, recently discovered documents and nearly 100 interviews with camp survivors and perpetrators, many of whom are speaking on the record for the first time. Their stories are brought to life through the innovative use of archive footage, dramatic recreations of key moments, and their testimony.
