Comedy Of Innocence

Camille (Nils Hugon) frightens his mother, Ariane (Isabelle Huppert), during his ninth birthday party when he proclaims that she's not his real parent. The next day, he leads her to the home of violin teacher Isabella (Jeanne Balibar), whose son died by drowning two years ago and would now be the same age as Camille. Isabella, a mentally unstable patient of Camille's psychiatrist uncle, Serge (Charles Berling), claims the boy is her dead son reincarnated -- and moves in with the family.
