The film
When a younger girl called Emily Rose dies, everyone puts blame on the exorcism which was performed on her by Father Moore prior to her death. The priest is arrested on suspicion of murder. The trial begins with lawyer Erin Bruner representing Moore, but it is not going to be easy, as no one wants to believe what Father Moore says is true.
