When an obsessive fan’s visit to legendary filmmaker Luigi Cozzi’s Profondo Rosso store and museum leads to a murder, it triggers a phantasmagoric freakout of vanished inventors, alternate dimensions, cursed books, lost films, and bizarre pajamas. Cozzi writes, directs, and stars as himself in this insane supernatural sci-fi splatter mystery that also features appearances by filmmakers Lamberto Bava and Dario Argento.
