4 mosche di velluto grigio

The drummer Roberto is pursued by an unknown person whom he accidentally stabs in a fight. The act was photographed: Soon Roberto receives threatening messages and is plagued by nightmares, causing his unstable wife to leave him. Argento lets the action glide abstractly, the unforgettable finale owes itself to the super slow-motion flow of a special camera that registers 30,000 images per second.
