The Old Dark House style mystery thriller has an murky make-over in the Agatha Christie-meets-Lucio Fulci feature debut of director Jack McHenry. In stunning Black & White, together with cut glass British accents and a dodgy American in the Cocktailparty combination, a complex 1930s soiree at an isolated country mansion descends into carnage, gore and demonic possession as rivalries and old friendships are put to the test once a gateway into Hell opens up.
