The Man Who Saw Too Much tells the story of 106-year-old Boris Pahor, believed to be the oldest known survivor of the Nazi concentration camps. He was sent to Dachau, Dora, Harzungen, Bergen-Belsen and Natzweiler – one of the Nazis' least known but most deadly camps. Twenty years after the war, Pahor wrote an extraordinary book about his experiences called Necropolis - City of the Dead.
