Mia has locked herself inside her recently deceased mother's rundown, crumbling house. Armed with a litany of books detailing ancient cultures and rituals, she tries desperately to reach out to the other side and speak to her mother. But when she succeeds, she gets more than she bargained for. Waiting alongside her mother is something monstrous, something that Mia recognises instantly. As she tries to survive the night and escape the ritual alive, Mia is forced to confront a variety of evils - ones from both without, and from within.

Inside a den fortified to keep people out, Josh finds himself trapped with four unstable drug dealers and a possessed bag of meth. An ancient evil with a proclivity for gratuitous acts of violence makes its way through the whacked-out inhabitants, one by one. As eyeballs are pulled out and throats are slit around him, Josh realises that, to survive, he must claw, cut and burn his way out.
