La coupure (2006)

　　Two people are caught up in an all-consuming and forbidden love in this drama, the first feature from director Jean Chateuvert. Christine (Valerie Cantin) is married to Mario (Michael Kelly), a successful businessman, ...展开and is the mother of two children. However, Christine has a lover, a man she's known long before she was married -- her brother Christophe (Marc Marans). Both Christine and Christophe are aware of the dangers of their incestuous relationship, and have both attempted to stop it -- Christophe even introduced Mario to his sister in hopes that they would hit it off and their affair would come to a end. But neither Christine nor Christophe have the strength to put an end to their relationship, and while Mario has recently earned a promotion at work that will necessitate moving to a new city (a job Christine urged him to get), she hasn't had the courage to tell her brother the news.
