Lucie and Pierre, brother and sister in their 20s, share an intimate relationship with each other and their group of friends. Pierre, unstable and narcissistic, is the leader of the group. They have youth and beauty on their side, and it seems that nothing can resist them. One day Pierre is found savagely murdered. As the police investigation drags on, Lucie, aided by her friends, decides to find out who killed her brother. They discover that Pierre used his youthful body to prostitute himself in parties with corrupted members of the high society. As the plot thickens, multifaceted cross-hatched dependencies and humiliations come to light. The shocking and unanti- cipated ending of the movie prompts as many questions as it answers about how sexuality can both inspire and defeat us. The film was based on a true story. The imagination of the two filmmakers was provoked by the fact that the protagonists had never explained the reasons of their act. In projecting a real event into fiction, Jean-Marc Barr and Pascal Arnold wanted to explore how adolescents could end up in such extreme situations. According to them, today's young adults can carry out crimes and a presumed unexplainable revolt can give access to the intimate sphere of their personality.
