Have you ever wondered what goes on in the mind of someone who is demonically possessed? Jeffrey does.
After the death of his father and a dirt bike accident, he starts experiencing psychological stress, nightmares, sickness, and horrible versions. His mother and sister are frightened, withdrawing from his presence.
Soon, a demonic entity emerges. Within Jeffrey's mind, there is a fight for control. It's a fight he cannot win as it destroys his personality, identity, and soul. All he can do is wait for his Parish Priest, Father Matthew to help him.
