On an isolated stretch of land 50 miles outside of San Francisco sits the most haunted house in the world. Built by Sarah Winchester, the eccentric firearm heiress to the Winchester Repeating Arms fortune, it is a house that knows no end.

Renowned for its enormous size, its architectural curiosities, and its lack of any master building plan, the Winchester house was constructed in an incessant twenty-four hour a day, seven day a week mania for decades. It stands seven stories tall and contains hundreds of rooms with numerous oddities. To the outsider it looks like a monstrous monument to a disturbed woman’s madness. But Sarah is not building for herself, for her niece or for the brilliant Doctor Eric Price whom she has summoned to the house. She is building a prison, an asylum for hundreds of vengeful ghosts, and the most terrifying among them have a score to settle with the Winchesters.
