The Lost Son

A moral battle ensues when private detective Xavier Lombard (French actor Daniel Auteuil) is hired by a wealthy family to find their son who has disappeared. The trail Lombard follows leads him to the seamy outskirts of society that are unseen by such wealthy families, and ultimately to a hideout where he finds many strange things except for the boy. When Lombard discovers that the boy is caught up in dangerous circles, he must delve into a morally corrupt world in order to find the boy. (official distributor synopsis)
