His name is Bruno Hamel, he is thirty-eight years old and a surgeon. He lives in Drummondville with his small family - his wife Sylvie and Jasmine, his seven-year-old daughter. Like all happy people, he has an unremarkable life. Until Jasmine is raped and murdered on a beautiful autumn afternoon. From that moment on, the world of the Hamel family crumbles. When the police arrest the murderer, a terrible plan takes root in Bruno's darkening mind : he will snatch the monster and make him pay for what he did to Bruno's little girl.
