- The film tells the story of how, in post-war Spain, Narcisa (played by Aria Bedmar), a novice with supernatural powers, arrives at a former convent, now a school for girls, to become a teacher. As the days go by, the strange events and increasingly disturbing situations that torment her will eventually lead her to uncover the terrible web of secrets that surround the convent and haunt its inhabitants.
