Stanchfield plays Nina Locke, a widowed single mother of three who packs up her kids and moves them into her late husband’s childhood home, Keyhouse, in Massachusetts. They soon discover it 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 Nina starts her own investigation to find out what more about her husband’s murder. 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.
