Incredibly, the film \"The Exorcism of Emily Rose\" is based on real events that happened in the year 1976, when during the expulsion of the demon girl tragically died. The session is conducted by a priest, and the sheer ritual was officially endorsed by the Catholic Church, but despite this, the priest was convicted. The priest did not put up with this injustice and began its investigation in search of evidence of the existence of this demon and the History of its occurrence among people.
