La Balance

In the French-made film (La Balance), a couple get caught between the French underworld and the cops who pledge to destroy it.

The man is a one-time mobster, now pimp named Dede (Philippe Leotard) who's forced to squeal on some mob-land biggies in exchange for his acquittal from any connection to crimes committed and to get the cops off the back of his prostitute wife Nicole (Nathalie Baye). This one's full of chase scenes, profanity (it's dubbed in English), and violence.

It was awarded many Caesar awards (the French equivalent of the Oscar).
