Cop Au Vin is a classic Claude Chabrol thriller set in the belly of a small town full of dark plots, delicious secrets, and multiple murders.

Stéphane Audran plays a cruel, wheelchair-bound invalid who bullies her teenaged son Louis (Lucas Belvaux) into abject obedience. The pair is threatened by a conniving trio of "upright citizens" that want to buy her property as part of a deal for a lucrative development project. However, the two eccentrics, who are given to reading everyone's mail before it is delivered, won't sell. With townsfolk dropping off left and right in a series of gruesome murders, it requires the deceptively charming Inspector Lavardin (Jean Poiret) to get to the bottom of it all. A masterful jeu d'esprit, Cop Au Vin also stars Michel Bouquet and Pauline Lafont.
