After their foster father, Father Peters, is killed in a mysterious attack at the Vatican, sisters Jo and Maddie are plagued by strange visions. In these visions, they see a little girl undergoing an exorcism. Maddie, in particular, is increasingly tormented by these terrifying visions. Jo suspects her sister is possessed by a demon and, in her distress, turns to the mysterious priest Marco, who is familiar with the Vatican's secret exorcism rites. But to successfully exorcise the demon, she must first be ordained a priest herself—a far more dangerous undertaking than she imagined!
