Journalist Thet Sambath’s family was among an estimated two million executed during the Khmer Rouge’s rule of Cambodia. ‘Enemies of the People’ documents Sambath’s journey to discover the truth as he obtains graphic confessions from a wide range of murderers, including ‘Brother Number Two’ Nuon Chen, Pol Pot’s deputy between 1975 and 1979. Codirector Rob Lemkin will appear in person at the Balboa Theater.
