Apparently, Duch was a math teacher before he joined the Khmer Rouge. As to what drove him to orchestrate such atrocities at S-21, assuming he orchestrated them, is something that Nic Dunlop was very curious about. According to the review, since he was a child, Nic had a picture of Duch in his wallet and would carry it around with him wherever he went. When Nic was older, Nic became a photo journalist who found himself assigned to cover an aid camp somewhere in the border of Thailand and Cambodia.

According to the review, despite the interviews granted to Nic, he still does not understand how Duch could have orchestrated the atrocities.
