A reclusive writer seeking solitude purchases a Victorian mansion deep in the Berkshire Mountains, drawn to its isolation and Gothic atmosphere. But her dream of a peaceful writer's retreat quickly turns into a nightmare when she discovers why the previous owner vanished without a trace. Strange marks appear on her windows, impossibly pale figures test her defenses nightly, and her only companions - her black cat Luna and a concerned local sheriff - can't protect her from what lurks in these ancient woods. This supernatural thriller explores how the very isolation we sometimes crave can make us most vulnerable to forces beyond our understanding.
