Throughout the 1970s, nearly 1.4 to 2.2 million people died at the hands of the communist Khmer Rouge regime. The regime, based on trying to rewind the clock back to year zero, targeted hundreds of thousands of people and forced children against their parents.

One of the most gripping and emotional movies, The Killing Fields, is still one of the best depictions of life under the Khmer Rouge. Still to this day, travelers pay their respects at the Tol Sleung genocide prison and the killing fields themselves.
