Some doors should never be opened.

When young Edward Morris begins speaking in tongues and crawling across walls, his family fears demonic possession. When the Church fails to intervene, his father turns to James Bennett, an exiled priest, and Annie Carter, his sharp-minded assistant with a haunted past.

James and Annie arrive expecting a routine exorcism, but the more they investigate Edward's condition, the more they realize something is profoundly wrong with the Morris estate itself. The house whispers. Portraits shift. Shadows move without a source. And as the pair unearths the family's buried history, it becomes clear that the possession isn't confined to the boy.

As the house tightens its grip and darkness spreads, James and Annie must confront an evil rooted far deeper than they ever imagined, one that threatens not just a child, but the soul of an entire family.
