The mean, cobbled streets of the Belleville quartier in Paris yield up another story of love, money and death, and all the requisite shootouts, car chases and lowlife infighting are delivered with great verve and pace: but what really distinguishes this excellent thriller is Swaim's strength on the emotional front. The flics set up a pimp (Léotard) to be a new informer ('balance') by leaning on the whore he very much loves (Baye); the loyalties become more and more crossed until betrayal is the only means to salvation. Léotard is superb as the crook with a heart of glass; Baye at last breaks out of her nun's habits and gives us a tart with the strength of ten; Berry is the sympatico cop. They order these things better in France. CPea.
