Pierre Hoffman joins a prestigious school as a substitute teacher and soon notices, among some of his students, an unjustified hostility and a spark of violence in their eyes. Is it because the unspeakable tragedy they have just experienced? Is it because they seem to be extraordinarily gifted children? Is it because they have lost all hope for the future? From curiosity to obsession, Pierre will try to unlock their secret.

The film takes place in Paris, where two cops are competing for the vacant seat of chief of police while in the middle of a search for a gang of violent thieves. The movie is directed by Olivier Marchal, a former police officer who spent 12 years with the French police before creating this story, which is taken in part from real facts that happened during the 1980s in France.

Loic and Sophie are siblings living with their mother in a block of flats. The impetuous, promiscuous Loic is a talented photographer about to make it to the big time, but being pulled back by loyalty to his best friend and ex-lover, both junkies. Sophie, a schoolgirl on holidays, is quietly undergoing a sexual awakening, observing from a distance Loic's milieu; she begins an affair with his business partner to Loic's quasi-incestuous disapproval. Loic is spotted by a prominent editor, but becomes increasingly unhinged, by his friend's violent struggles with dealers, by his lover's demands, by Sophie's 'betrayal', by his own 'demons'. Tragedy inevitably strikes.
