A series of films based on the cult gothic soap opera Dark Shadows (1966–71). Each film re-tells a popular storyline from the show: in House of Dark Shadows, the story of the vampire Barnabas Collins; and in Night of Dark Shadows, the story of the witch Angelique, from whom Barnabas received his curse of vampirism.
Barnabas Collins searches for a cure for vampirism in order to marry a woman resembling his long-lost fiancée Josette.
Recently married, Quentin and Tracy Collins have just moved into Collinwood, a New England estate that has long been in the Collins family and which Quentin has just inherited. They soon find themselves plagued by spirits of past residents.
