The Big Racket (1977)

A by-the-books cop struggling to bust a brutal protection racket in Rome is forced to throw the rules out the window when the vicious gang attempts to cement their status by moving into the drug trade in director Enzo G. Castellari's tough-talking poliziotteschi. As the citizens of Rome continue to suffocate in the cold grip of fear, it's up to determined inspector Nico Palmieri (Fabio Testi) to take back the streets from the murderers and rapists who terrorize the population and give the cruel thugs a hard lesson in street justice. When the only language that the criminal element understands is violence, Inspector Palmieri is more than willing to communicate in terms that will get the message across.
