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.
