Bille en tête (1989)

Based on a popular novel with the English title Devil in the Flesh by Alexandre Jardin, this little drama tells the story of Virgile (Thomas Langmann), a sixteen-year old boy who has grown tired of being a virgin, and decides to seduce Carla (Kristin Scott-Thomas), an older woman. Rather to his surprise, despite his callowness, she proves to be quite willing.
