Now Tess’s new medication seems to be working as she and her mother move to a new town seeking a fresh start.

Doctors, sedatives, and priests (suspecting possession from beyond the grave) fail to help, leading Tess to be institutionalised after attempting to take her own life. While she is under observation, a local priest fears that it is Lucy attempting to return by taking control of the troubled Tess, and suggests exorcism as the only way to drive the dead girl out and bring peace to both of these tortured young souls…
