French fantasy in which an ordinary man and woman attempt to deal with the birth of an extraordinary child. Katie (Alexandra Lamy) works at a chemical factory and finds as little enjoyment in the work as she does in her mundane life as a whole. Things appear to pick up when she begins a relationship with her Spanish co-worker, Paco (Sergi López), and the pair have a baby, Ricky (Arthur Peyret). When Katie returns home one day and discovers that the baby has a series of bruises on his back, she rashly accuses Paco of child abuse and he storms out in anger. It turns out, however, that the bruises are in fact the beginnings of an extraordinary physical characteristic; one that will change their lives forever.
