In this dark romance, a wealthy French banker (Benoît Poelvoorde, Man Bites Dog) and his dominant mistress (Laetitia Casta, Gainsbourg: A Heroic Life) have made a routine of pushing each other to their limits through increasingly extreme and dangerous desires. But tension in the relationship grows when they negotiate a marriage contract that may be more than either of them are willing to fulfill. When negotiations stall, the banker's fetishistic interests start to bleed into their personal lives, threatening to destroy them both. Passion, power, and violence eventually become one and the same for the doomed lovers in Hélène Fillière's stylish and moody TIED.
