Price of Love (1955)

Because he loved a trainer named Suzy too much, honest Pierre Menard wasted his life and died. Innocent, but implicated in the ransacking of a jewelry store, he receives a five-year residence ban, which he ignores, only to find himself reduced to joining Paulo's sinister gang. The police finally arrest him and force him to become an informer if he doesn't want to leave Paris. He accepts and signs his death warrant.
