A self-absorbed adolescent girl forms an unhealthy fixation on a handsome volunteer fireman in director Claire Simon's emotional teen drama. Livia (Camille Varene) is a fifteen year-old girl who lives in the south of France with her divorced mother. As the summer heat begins to radiate Livia spends most of her days trotting around the small Provençal town atop a horse from her father's farm. A frequent target of ridicule amongst her peers, Livia's horse emboldens her with a sense of superiority that she just can't seem to achieve in the classroom. When her father comes to claim the horse and Livia is forced to face her tormentors eye to eye, she begins to turn her attentions increasingly towards happily married husband and father Jean. A kind volunteer fireman who treats Livia with a respect rarely afforded to the girl by her peers, Jean may be old enough to be Livia's father though a strange attraction begins to develop between the pair. Later, as the young girl's infatuation with the firefighter begins to grow and she casts aside her inhibitions to pursue him romantically at any cost, the relationship shared between Livia and Jean threatens to take a tragic turn.
