Een vreemde satanische macht houdt zich schuil in het dorp Dunwich en heeft het op een jonge maagd voorzien. Wilbur Whateley heeft namelijk het boek Necronomicon geleend (een boek met oude rituelen om buitenaardse goden naar de Aarde te brengen) en de maagd dient onderdeel te zijn van de ceremonie.
Nee, helaas is The Dunwich Horror nog niet beschikbaar op Netflix in Nederland.
