Boredom (1998)

Martin is a middle-aged philosophy teacher in the midst of a mid-life crisis. Lacking direction or purpose in his life, he initiates an affair with Cécilia, a young artist's model who might have killed her former lover with the intensity of her sexual appetite. They share a purely erotic relationship as an intellectual abyss separates them. Before long, he needs to possess her and cannot resist a sharp descent into violent jealousy.
