Based on the true story of firearm heiress and architect, Sarah Winchester, this original historical thriller tells a strange and unforgettable tale. Sarah became one of the wealthiest women in the world after the untimely death of her husband in 1881. As fate would have it, the rifle that brought Sarah riches also gave rise to menacing guilt and grief over the lives it took. 'Build a house,' a psychic advised her, so she may save her soul and appease the restless dead. And so, Sarah embarked on a 38-year project building the Winchester Mystery House.
