The farmer Ely (Randy Colton) finds a slaughtered coyote and his daughter Isabelle (Kristin Erickson) covered on blood and brings her home. She attacks her father and her mother Blanche (Leslie Fleming- Mitchell) and their employee Miguel (Del Zamora) tells that she is possessed and needs a priest and not a doctor. Priest Jacob (Cameron Daddo) arrives and along his exorcism, the demon Perlocus deceives the family and everyone that is trying to help Isabelle with lies and sins.
"Blackwater Valley Exorcism" is another movie of exorcism and the difference is the terrible screenplay and only Kristin Erickson has a convincing performance. The non-likable characters are not well developed and the messy story seems to be a soap opera of horror genre, with shallow dramatic situations. My vote is three.
Title (Brazil): "Exorcismo – A Execução" ("Exorcism – The Execution")
