The Psychotronic Video Guide describes this film as "the strongest, most imaginative, and visual witch movie since Ken Russell's the Devils." It tells of the strange friendship between two young girls Justine and Alucarda, and how their relationship destroyed the lives of those around them in a torrent of blood, death and damnation. This legendary lost film contains images that will shock and disturb. Perverse, erotic chiller from Juan L. Moctezuma is a disturbing tale of Justine and Alucarda, two young orphans in a 19th-century convent populated by fanatical nuns. The girls come across a tomb in the woods and enter it, only to leave possessed by demons who lead them into satanic rituals and lesbianism. Soon, the pair are pitted in battle against the nuns, and the whipping, screaming and blood begins! AKA: "Mark of the Devil 3."
