Roshane Saidnattar, a young film director and survivor of the death camps in Cambodia, meets with Khieu Samphan, the theorist leader of the Khmer Rouge, for several days. Confronted with either the silence or the out-of-date speech of the leader, the filmmaker, Roshane, and her mother, also a survivor, go back to Cambodia and find the strength to speak out. Survive in the Heart of the Khmer Rouge Madness mixes the memories of the director, the testimony of her mother and unreleased archives. This film, by its intimate echo, reveals a part of the madness that destroyed a whole country.
