In Le Dernier Souffle/Deep End, a policeman is forced to discover just how far his family has chosen to live on the other side of the law. Quebec peace officer Laurent (Luc Picard) arrives at a crime scene to discover a particularly brutal murder has been committed -- and that the victim was his brother Martin. Laurent is determined to get to the bottom of the killing, but the deeper he digs the more unpleasant the facts become. It seems Martin was being investigated by the police at the time of his death; he was a member of a white supremacist organization in cahoots with Russian gangsters and tied to many illegal activities. Laurent's unpleasant discoveries don't stop there, when he finds out his father is a terrorist wanted by the law, and the trail of suspects in Martin's murder leads him to a small town in Arkansas and a fanatical right-wing militia group. This French-Canadian drama features dialogue in both French and English, with different parts of the story taking place in Quebec and the United States.
