In 1976, a timid sound engineer (Toby Jones) arrives in Italy to work on a mysterious horror film, mixing bloodcurdling screams with the grotesque sounds of hacked vegetables. But as the on-screen violence seeps into his consciousness, reality and fantasy become blurred in nightmarish ways.

Daringly original and masterfully constructed, this inspired homage to 70s Giallo horror is a devastating assault on the eyes, ears and brain - drawing comparisons with the films of David Lynch and being hailed as a modern cult masterpiece from Peter Strickland, the hugely acclaimed director of Katalin Varga.
