After their father is murdered under mysterious circumstances, the three Locke siblings --Kinsey, Tyler, and Bode (Emilia Jones, Connor Jessup and Jackson Robert Scott)-- and their mother move into their ancestral home, Keyhouse, which they discover is full of magical keys that may be connected to their father's death. As the Locke children explore the different keys and their unique powers, a mysterious demon awakens -- and will stop at nothing to steal them. From Carlton Cuse ("Lost", "Bates Motel") and Meredith Averill ("The Haunting of Hill House"), the series is a coming-of-age mystery about love, loss, and the unshakable bonds that define family.
