Plot

During an exorcism ritual, Hannah Grace—possessed by a demonic entity—levitates and nearly kills a priest before her father, Grainger, ends the ritual by suffocating her with a pillow. As he mourns over her body, a fly lands on her hand, and it twitches, suggesting the presence of the demon remains.
