The Hag

Michael Latimer has the perfect life. Until the night he can't move. As the head of a prestigious English department with a beautiful wife and a stellar career, Michael is a man of logic and science. But when he finds himself pinned to his bed, immobile and tormented by ghastly visions, his rational world begins to fracture. He clings to the medical diagnosis of sleep paralysis-a safe, clinical explanation for the darkness pressing down on his chest.
But as the terrifying night visits intensify, Michael's research leads him away from science and down a paranormal rabbit hole. He begins to question the nature of evil, the reality of the world, and the true identity of his wife, Kathy. Hoping to save their crumbling marriage, Kathy takes Michael to her parents' remote cabin in the Ozarks for rest. But the isolation only feeds his hostility. Convinced he's having an affair, Kathy checks his phone-only to find a horror far more disturbing than infidelity.
In the deep woods of the Ozarks, the "Old Hag" isn't just a medical phenomenon. She's a nightmare that's finally come home.
