synopsis

Following a near-death experience in a car crash, teenager Cassie Stevens finds herself haunted by a shadowy figure... something has followed her back from the other side. As these visions escalate, Cassie discovers that everyone haunted by this specter has died. No shrink can help her, only a priest, Fr. McCready, who can perform the only remedy Cassie may have - an exorcism. Will it work, will she die? Or will it free the demon.
