France,early 70s. Lucia, a ten year old girl, who disappeared a few months earlier, was found wandering on the road. Her abused body bears no trace of sexual assault. The reasons for her abduction remain mysterious. Traumatized, silent, she is placed into a hospital where she becomes friend with Anna, a girl of her age.

15 years later. The door bell dings at the door of an ordinary family house. The father opens and faces Lucia, armed with a shotgun. Persuaded to have found her executioners, she shoots.
