Early in the film we meet Mara Williams, an artist Alex once exorcised, who has escaped from a mental hospital and come to Alex at his church in the USA because she has a feeling that something terrible is going to happen to him. The police come looking for her, but Alex lies and denies that he's seen her and through this exchange we learn that Mara was in the hospital because she had tried to kill Alex during the exorcism. Mara goes to Rome with Alex after promising that she won't try to kill him again.
