An indulgently sleazy and creative American take on the giallo, as filtered through an 80's slasher film structure, Terrence O'Hara's DARKROOM is a suspenseful and red herring filled murder mystery. Featuring stylish photography from David Makin and increasingly nasty kills, Vinegar Syndrome brings DARKROOM to for the first time, sporting a fresh restoration of its original camera negative and new interviews with its stars.
