L'ivresse du pouvoir (2006)

A character study. Jeanne Charmant-Killman is an investigative magistrate, tough minded, swift moving, taking on a group of political fixers who pay bribes and skim large sums for personal use. She breaks them one at a time. Meanwhile, her work takes its toll: relations with her husband are strained, and the group under investigation strikes back by tampering with the brakes of her car and placing a mole in her office. Can she stand up to the pressure, and what's her reward?
