What no one knows is that in order to make his way in the exclusive world of luxury design, Valentin had to lie about his modest, northern origins. When his mother, his brother and his sister-in-law show up at the gala, the two worlds are on a collision course, made even more explosive when Valentin gets hit by a car.
