Who was Pol Pot, the criminal leader of the Red Khmer Rouge? This portrait draws on archival footage and rare eyewitness accounts, including the only interview with Pol Pot made before his death by American journalist Nate Thayer. Pol Pot, whose real name was Saloth Sar, remains an enigma. No other revolutionary leader has left so few traces. Pol Pot almost always refused to give interview, not only when he was in power but even later on, when he took refuge with his troops in the Cambodian forests. But in 1997, the Khmer Rouge movement imploded.
