On April 17, 1975, the communist Khmer Rouge, led by its secretive prime minister Pol Pot, took over Cambodia. They cut the nation off from the world and began systematically killing and starving two million of their people. Thirty years after their fall, a man named Duch, who had served as Chief Prison officer at the regime's central prison complex, stood trial for war crimes and crimes against humanity. Journalist Thierry Cruvellier takes us into the dark heart of Cambodia's Khmer Rouge, using the trial to tell the horrifying story of this terrible chapter in history. The Master of Confessions: The Making of a Khmer Rouge Torturer is an account of a Chief Interrogator's trial for war crimes.
