Rithy Panh uses clay figures, archival footage, and his narration to recreate the atrocities Cambodia's Khmer Rouge committed between 1975 and 1979.

“For many years, I have been looking for the missing picture: a photograph taken between 1975 and 1979 by the Khmer Rouge when they ruled over Cambodia… On its own, of course, an image cannot prove mass murder, but it gives us cause for thought, prompts us to meditate, to record history. I searched for it vainly in the archives, in old papers, in the country villages of Cambodia. Today I know: this image must be missing. I was not really looking for it; would it not be obscene and insignificant? So I created it. What I give you today is neither the picture nor the search for a unique image, but the picture of a quest: the quest that cinema allows.” – Rithy Panh
