Dany, the Arnault family’s teenage son, has disappeared. The case is assigned to François Visconti, a world-weary and disillusioned detective. He sets out to find the missing teenager while he is reluctant to take care of his own son, Denis, 16, who seems to be mixed up in drug trafficking. When Mr. Bellaile, Dany’s French tutor, learns about his former student’s disappearance, he offers his services to the detective. He is very interested in the investigation. Too interested, perhaps.
