The Order of the Angels, residing in an ominous countryside cloister, are charged with a dark and secret duty. Sister Jodie (Nora Jacobs) arrives to find the order in the midst of turmoil: the nuns are hearing strange sounds in the middle of the night and one of their number has gone missing. As the sisters begin to experience cases of demonic possession, it is up to Jodie and her new friend, Sister Salka (Katharina Maria Trenk), to discover the source of these unnatural occurrences…even if it means staring into the very face of hell.
