Overview.
Nhem En was 16 years old when he was the staff photographer at the Tuol Sleng Prison, also known as Security-21, where from 1975 to 1979 approximately 17,000 people were registered and photographed, then imprisoned and tortured before being killed. Only eight people are documented to have walked out of S-21 alive. Three of them tell their stories in the film. Bou Meng, 34 years old at the time, survived because the prison needed an artist to paint portraits of Khmer Rouge leader Pol Pot. Chum Mey, 42 at the time, survived because he could fix sewing machines. Chim Math, 20 at the time, doesn't know why she survived.
