Plot
On October 30, 1989, Maria Rossi committed a triple murder during an exorcism performed on her. The Catholic Church became involved, and she has since been in a Catholic psychiatric hospital in Rome. Her daughter, Isabella, learned of the murders from her father, who died three days after telling her.
Twenty years later, Isabella is in the process of filming a documentary with filmmaker Michael Schaefer about exorcisms and, to find out more about her mother, she visits Maria in Rome and meets two priests, Ben Rawlings and David Keane. Maria speaks in different accents and soils herself while screaming in an unidentified language. She has inverted crosses carved into her arms and her bottom lip and tells Isabella that killing a child is against God's will. Isabella had an abortion years ago and her mother had no way of knowing that—a sign that showed possible possession. David and Ben take her on an unsanctioned exorcism performed on Rosalita, a young woman. Rosalita calls Isabella by her name, despite not knowing her, and attacks the crew. Eventually, they get her under control.
