Catherine, a rebellious pre-teen deeply affected by her parents’ divorce, loves to play games of chicken where she crosses busy, dangerous streets with her eyes closed. She becomes friends with the girl next door, the quiet Ariane, to the consternation of Ariane’s father, David. Although he appears to be a model father, David is in fact obsessed by the need to protect his daughter. And so he tries – unsuccessfully – to prevent Ariane from coming under Catherine’s bad influence. Ariane takes up smoking, starts telling lies, and begins to explore her sexuality. While Catherine’s mother attempts to seduce the handsome, and single David, he sets a fiendish trap for Catherine. For Catherine, living dangerously is no longer a game, and she has to summon all her strengths in order to survive.
