We then fast forward some years and a grown up Mariale is living in a mansion with her husband Paolo. She has mental problems and is often given drugs to quell the problem. She invites a group of friends to stay at the house with her and her husband, but the party soon degenerates into an orgy and it's not long before the guests are being picked off one by one. (imdb)

A rogue cop and a merciless crime lord take their bloody battle to the streets in director Massimo Dallamano's brutal poliziotteschi. When the battle between the determined lawman (Marcel Bozzuffi) and the relentless criminal (Ivan Rassimov) goes public, there's no telling how things will turn out as the bullets fly and the frightened citizens run for cover. Prolific soundtrack composer Stelvio Cipriani (Death Walks in High Heels) provides the hard-driving, funk-infused score. (allmovie.com)
