El más salvaje entre todos (1984)

Original title: Rue barbare

In this strange and beautiful crime drama, Bernard Giraudeau is Daniel Chetman, someone who wants to leave the life of violence he knew in his neighborhood -- and cannot do so because his nemesis, a strutting street gangster now involved with organized crime, continues to terrorize the inhabitants of Chetman's turf. After much spilled blood, a parade of ugly underground types, and various sexual scenes, Chetman reduces the forces of evil to a reasonable level of opposition -- but who knows if the neighborhood will be different in the end...
