In 1989, Maria Rossi killed two priests and a nun whilst having an exorcism performed on her. She was deemed legally unfit to stand trial and was sent to a psychiatric hospital in Tiber.
Twenty years later, Maria's now grown up daughter, Isabella, decides to travel to Rome to visit her mother. She brings along her friend, Michael, to document the trip. She is also studying exorcisms at college and thinks that the trip will be educational and insightful.
Isabella arrives in Rome and interviews two priests, David and Ben. They know a thing or two about exorcisms and tell an interested Isabella what they know. They invite Isabella to an exorcism of a woman called Rosalita, who proceeds to attack the group.
Shaken by the experience, Isabella doesn't abandon her project and goes to visit her mother, Maria, in the hospital. However, it doesn't go at all well, culminating in Isabella being forced from the room by doctors attempting to calm Maria down.
Ben and David have the idea of trying their exorcism techniques on Maria, with Isabella's consent. But there is one thing that Ben and David didn't bargain on happening, resulting in a very bloody climax for the two priests, Isabella and Michael.
