When Evelyn Harper and a group of paranormal investigators arrive at Harper Manor—an abandoned estate with a dark and twisted history—they expect to document haunting phenomena for their show. But the house has other plans. As they delve deeper into the mansion's eerie halls, they encounter strange whispers, shifting shadows, and terrifying visions that test their sanity. The house is alive, feeding on their fear and turning the very walls into a labyrinth of nightmares.

As the group fights to escape, they realize the house is not just haunted—it's possessed by a malevolent force that traps and consumes souls. One by one, their friends fall under the house's control, becoming puppets of the shadow entity that lurks within. With time running out, Evelyn must face the horrifying truth: the house has been waiting for her, and it won't stop until it claims her, too.

In a fight for survival, Evelyn and the few remaining members of the group must confront their deepest fears or risk becoming part of the house's dark legacy forever.
