In a remote town on the Thai border lives a man accused of mass murder. Khieu Samphan, Pol Pot's Head of State, was the public face of the Khmer Rouge. Now an old man, he claims he had no idea his party was butchering it's own people. "I was totally ignorant of all of this". Victims like Seng Theary, whose family were murdered by the Khmer Rouge, blame Samphen for their suffering. "How could he not know? He was one of the top three Khmer Rouge leaders". But even they expect little from the trial. As lawyer Rupert Skilbeck states; "The evidence against some of the defendants is not very strong".
