Do you believe in spirits? Can you say for sure whether they exist or not? At 50 kilometers from San Francisco stands a secluded house, whose structure defies any logic. It was built by the heiress of the world-famous arms company Sarah Winchester. She remained completely alone, she decided to build this seven-storey building with labyrinths instead of corridors and hundreds of rooms. Outwardly this house is more like a monument to Sarah’s insanity. The inconsolable widow almost every day adds something new to him, moves it even more. And it’s not for yourself, not for your niece or anyone else alive – it’s for ghosts. For those beings who want to take revenge on the Winchesters for the weapons they have created. And some of these avengers are very strong.
