Between April 1975 and January 1979, the Democratic Kampuchea regime killed approximately 1.7 million people. Since 2006, the trial of the former Pol Pot dignitaries has begun in Phnom Penh. As forms of compensation for the victims, it offers mainly commemorative practices inspired by the “duty to remember” and a mental health support. A narrative that promotes the idea of a passive and traumatized Cambodian Nation.Nevertheless, for more than twenty years, Cambodian society has moved on by its own means. They lie in a deeply resilient religious culture where the well-being of the living depends on the well-being of the dead and where circular time produces a type of memory that turns itself alternatively on and off. This film, based on a scientific study embedded in a poetic form produces evidence of ongoing mutations which raise disturbing questions for the contemporary world.
