À la suite de l'incendie criminel d'une colline dont la propriétaire est la fille d'un homme qui baignait dans le trafic de drogue avant d'être récemment assassiné, deux journalistes décident d'enquêter sur l'affaire.

Directors Jean-Henri Roger and Juliet Berto begin this thriller with sequences on the contemporary politics of southern France and the infiltration of organised crime into real estate development there: crime bosses were torching forest tracts to make way for their development schemes in the early 1980s. In the fictionalised story, Paula Barretto is caught in this underworld because her father was involved in the drug business, her brother is in the real estate scam, and her lover is an armed thief. Although she tries to get out of her corrupt and dangerous environment, it is not an easy task when even the police officers cannot be trusted, and the underworld has informants everywhere.
