Bruno Hamel (Claude Legault) is a surgeon who succeeded in life. He happily lives with Sylvie (Fanny Mallette), his wife, and Jasmine, their daughter. However, after Bruno let his daughter go play outside, Jasmine is found dead (and raped). When Jasmine's killer (Martin Dubreuil) is arrested and ready to go in court, Bruno has one idea in his mind: he wants to take the chance to kidnap the "monster". Besides, while in hiding (with the "monster" as a hostage), he tells to the police that he'll torture the killer for seven days and kill him. Afterwards, Bruno plans to turn himself in to the authorities. Nonetheless, will Sgt. Det. Hervé Mercure (Rémy Girard) manage to arrest both Anthony Lemaire and Bruno as the clock is ticking?
