The New York ripper (1982) Uncut, Lucio Fulci

A blade-wielding psychopath is on the loose, turning The Big Apple bright red with the blood of beautiful young women. As detective Fred Williams follows the trial of butchery from the decks of the Staten Island Ferry to the sex shows of Times Square, each brutal murder becomes a sadistic taunt. In the city that never sleeps, the hunt is on for the killer that can’t be stopped.
