The city of Turin is teeming with crime, and though it's up to two tough cops to clean up the streets, one of the pair is harboring a deadly secret in director Carlo Ausino's violent crime thriller. As if the fatal stabbing of a wealthy doctor, the brutal rape and strangulation of a seventeen-year-old girl, and a series of destructive smash-and-grabs weren't enough to keep police inspectors Danieli (Emanuel Cannarsa) and Moretti (George Hilton) working overtime, a growing gang war between the established local dons and an invading French crime syndicate threatens to blow the whole city sky high. Add to that the fact that the outwardly respectable Inspector Moretti is secretly prowling the moonlit streets to exact vigilante justice on the scum of the city under the moniker of his alter ego "The Avenger," and it's going to take more than one tough cop to ensure the safety of the scared denizens of Turin.
