This first collaboration between director Umberto Lenzi and star Tomas Milian remains both "a degenerate treat" (Mondo Digital) and "definitive Eurocrime" (DVD Talk): When a small-time criminal (Milian) kidnaps a wealthy industrialist's daughter, he'll trigger a depraved spree of class warfare, mass murder and the rage of a police commissioner (Henry Silva) determined to end the carnage.
