The Lost Son (1999)

The search for a missing man leads to the discovery of a den of depravity in the suspense thriller The Lost Son (1999). Daniel Auteuil stars as Xavier Lombard, a depressed detective who leaves London for the familiarity of France when his wife and daughter are murdered in a car explosion. The introverted investigator leads a joyless life, making a living as a private dick blackmailing adulterous couples, spending his free time befriending Nathalie (Marianne Denicourt), a high-class hooker. When a wealthy industrialist (Cyril Shaps) hires Xavier to find his missing son, he inadvertently finds himself embroiled in the sick world of the child sex trade. Marianne manages to lighten up the moody movie with a brief look at her beautiful French fanny. This girl from France will create a lump in your underpants!
