Nell Tiger Free stars in this supernatural horror prequel directed by Arkasha Stevenson.

Margaret Daino (Tiger Free) travels from America to Rome in 1971, ready to devote her life to God. Before taking her vows, she works at an orphanage where she is drawn to Carlita (Nicole Sorace), an orphan who appears distant from the other girls.

As they bond, Margaret uncovers a terrifying conspiracy within the church to bring forth the Antichrist and realises that she and Carlita are right at the heart of it. The cast also includes Sonia Braga, Ralph Ineson, Bill Nighy and Tawfeek Barhom.
