Roberto, a young drummer, is being stalked by a mysterious guy with dark sunglasses. In an attempt to put an end to this, he decides to confront him and follows his stalker into a deserted theater. But things escalate quickly, and he will become entangled in a gruesome murder and blackmail case.

Four Flies on Grey Velvet is a completely bonkers giallo from Suspiria director and mad genius Dario Argento. Leave plausibility at the door and revel (or squirm) in the maestro’s set-pieces and contraptions exploring music, voyeurism, technology, and murder. With moody music by Ennio Morricone!
