Carlo Lizzani delivers a defining moment in the poliziotteschi genre with this down and dirty, cinéma vérité-inspired thriller set in the seedy Milan underworld. Tomas Milian plays a detective on the trail of a gang of merciless bandits, led by Spaghetti Western star Gian Maria Volontè, in a story based on a real-life robbery gone wrong that took place in Milan in 1967. Mixing raw documentary style with violent action flourishes, Lizzani depicts a modern Italy rife with gangsters, gambling and prostitution, setting the stage for the renaissance of the crime film in the decade to follow. Featuring an original score by composer Riz Ortolani.
