A musician is stalked by a mysterious man. One evening he decides to follow the stalker and accidentally kills him after an altercation. It’s all over? Absolutely not, because someone has seen the scene and has photographed him. And now blackmails him. 4 mosche di velluto grigio is one of the first masterpieces of the Italian director Dario Argento and between murders and blood there is also some beautiful sequence with Francine Racette nude.
