Whatever walks there, no longer walks alone . . . Playwright Holly Sherwin is close to her big break. Having received a grant to develop her new play, all she needs is time and space to bring her vision to life. Then on a weekend away, she stumbles upon Hill House - an ornate if crumbling gothic mansion, near-hidden outside a small town. Soon Holly's troupe of actors - each with ghosts of their own - arrive at Hill House for a creative retreat. But before long they find themselves at odds not just with one another, but with the house itself. For something has been waiting patiently in Hill House all these years. Something no longer content to walk alone.
