The ordinary life of surgeon Bruno Hamel (Claude Legault) is destroyed when his daughter Jasmine (Rose-Marie Coallier) is raped and murdered in a park. Upon learning that the police apprehended the prime suspect, laborer Anthony Lemaire (Martin Dubreuil), Hamel plans to take revenge. He abducts Lemaire while he is being brought to his trial by drugging the officer driving the transport vehicle and brings him to a secluded cabin. Using a remote-controlled computer to conceal his location, Hamel calls the police to inform them that he plans to murder Lemaire in seven days, the seventh day being Jasmine's birthday. After killing him, Hamel will give himself up to the police.
