Black Tide

Dany, the Arnault family's teenage son has disappeared. The case is assigned to François Visconti (Vincent Cassel), a world-weary and disillusioned police chief whose wife has just left him. The policeman investigates to find the missing teenager while he is reluctant to take care of his own son, Denis, sixteen, who seems to be mixed up in drug trafficking. When Mr. Bellaile (Romain Duris), Dany's private teacher, learns about his former student's disappearance, he offers his services to the police chief.
