When an American family is invited to spend the weekend at the idyllic country estate of a charming British family they befriended on vacation, what begins as a dream holiday soon warps into a snarled psychological nightmare. From Blumhouse, the producer of The Black Phone, Get Out and The Invisible Man, comes an intense suspense thriller for our modern age, starring BAFTA award-winner James McAvoy (Split, Glass) in a riveting performance as the charismatic, alpha-male estate owner whose untrammeled hospitality masks an unspeakable darkness.
