"La Belle personne" is inspired by the celebrated 17th Century roman "La Princesse de Clèves", seen as the first modern novel in French literature. Christophe Honoré transposes the action from the court of Henry II to examine amorous pursuit in modern day Paris. Sixteen-year old Junie changes high school mid-year, following the death of her mother. She finds herself in the same class as her cousin Mathias, who introduces her to his friends. All the boys want to date Junie, and she chooses the quietest among them, Otto Clèves. But soon after, she encounters the great love of her life, Nemours, her Italian teacher. The passion that burns between them is, however, doomed. Junie refuses to give in to her feelings and persists in denying herself happiness, which in her eyes is merely illusory.
