Ugo Piazza (Gastone Moschin) is a career criminal released onto the streets of Milan after spending three years in an Italian prison. He wants give up crime and run off somewhere quiet with his stripper former girlfriend, but he's got a little problem to clear up first; everyone in Milan believes that Ugo stole and hid $300,000 from a local crime lord called The Americano (Lionel Stander). With the Americano's hired thug, a greasy psychopath named Rocco (Mario Adorf) whose favorite method of murder seems to be high explovies, and the largely ineffectual police both harassing him at his every move, how will Ugo stay alive and out of prison long enough to enjoy his retirement from crime?
Milano Calibro 9 is the first installment of director Fernando Di Leo's Milieu Trilogy, with the other two being La Mala Ordina (1972) and Il Boss (1973), both of with I want to see after watching the first installment. With both a blood soaked intro and finale, this film is quite a ride, I recommend it!
