Bruno, an up-and-coming film composer, moves into a secluded villa in Tuscany to write the score for a new horror film. However, real life begins to mirror the movie he is scoring as a vicious, masked killer begins murdering anyone who visits the house.
Stalked by a mystery assailant who sabotages his work, Bruno becomes an amateur sleuth. He suspects that an incriminating clue to the killer’s identity—and their connection to a former tenant named Linda—is hidden within the very film reels he is composing for. A Blade in the Dark (1983) - IMDb
