According to Amazon.fr, the Canadian thriller Les 7 jours du talion, an adaptation of Patrick Senécal's acclaimed novel, will be released on DVD in France on September 21.
Here's the description of the synopsis taken from a review I wrote:
Bruno Hamel (Claude Legault) is a surgeon by trade. He happily lives with Sylvie (Fanny Mallette), his wife, and Jasmine (Rose-Marie Coallier), their daughter. During one day, Bruno allows Jasmine to go outside in order to deliver invitation cards for her upcoming ninth birthday. Of course, he'd like to accompany his daughter, but he's too exhausted by his job and neither can Sylvie. However, as times goes by, Jasmine is unaccounted for. In the evening, Jasmine is found dead in the woods after she had been raped.
When Jasmine's killer, Anthony Lemaire (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. Afterwards, Bruno plans to turn himself in after he had killed Lemaire. Nonetheless, will Sgt. Det. Hervé Mercure (Rémy Girard) manage to arrest Bruno as the clock is ticking?
