Inspired by true events at the most haunted house in history. On an isolated stretch of land 50 miles outside of San Francisco sits a house that knows no end. Built by Heiress Sarah Winchester (Academy Award winner Helen Mirren) in an incessant twenty-four-hour-a-day, seven-day-a-week mania over decades, it stands seven stories tall and contains hundreds of rooms, staircases to nowhere and doors that open into walls. 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 (Sarah Snook) or for the troubled Doctor Eric Price (Jason Clarke) who has been 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...
