The Containment

A young girl is possessed by a dark and sinister being, and will fight with all her might to free herself from it. An apparent expert in exorcisms and her mother, a traditional medicine expert, are unable to get rid of the demon, until a nun gets involved, giving rise to suspicions more terrible than demonic possession: Is this a wicked demon at all, or is it a being that has come to help contain the evil already present within girl?
