This is a film about love and relationship, but the raunchiness means that it is not for everyone. François and Julie are a long-time Montreal married couple with 2 schoool-age daughters. They have separate professions, love one another, but their sex life has gone stale. Inspired by their younger friends, they decide to go to an open relationship sexually.Even as they start by meeting other swinger couples, it is obvious the two are reacting to the situation differently. They then exploring independently, sometimes going to sex clubs and sex parties. They learn about being open sexually while still being committed, When they find that their sexual turn-ons are different, they have to find ways to reconcile and work together, as per the name of the final "chapter".At its heart, this is a decent film about a committed relationship, though with a wild ride thru a series of sexual situations.I saw this film at the North American Premiere at Toronto International Film Festival, with director, cast, and producer Q+A. The sex scenes were rehearsed (clothes on) before the cameras arrived, though there was one mishap that required a later reshoot. Shooting on filrm meant that the action was more urgent, like a stage show, since they could not afford many reshoots. Meanwhile, "their daughters" were sisters in real life, and were encouraged to ad lib, likely leading to a more authentic reaction than could be scripted by an adult.
