For the last trial in his career Francois Roux, a lawyer specialized in the defense of non-violent activists and a supporter of civil rights himself, chose to explore the boundaries of the law and the morals. Kaing Guek Eav, aka Douch, is considered one of the bloodiest tortures of our times. From the preparation of the defense strategy to the final pleading, this film follows the backstage of one of the major international trials in the last few years and without any hesitation confronts the banality of evil, challenging the absolute notion of 'good'.
