For his second feature film - and first full collaboration with co-writer/producer/mentor Dario Argento - writer/director Michele Soavi unleashes a "mind-blowing" (Bloody Disgusting) "masterwork" (DVD Drive-In). In a Gothic cathedral built on the mass grave of a Teutonic purge, an ancient discovery by the new librarian will release an unholy maelstrom of madness, violence and demonic vengeance.
