Rulers of the City (1976)

Tony, a mob loan collector, is dissatisfied with his station in life. Though he dreams of one day being rich, he is stuck with the dead-end job of beating up borrowers who fall behind in their payments. After meeting up with Napoli, another mob enforcer who’s just been fired from his job, the two hatch a plan. Together, they will con mob boss Manzari out of a fortune, after which they can retire and live in luxury. Manzari, however, is not about to let them go so easily.
