Tyler, Kinsey and Bode Locke move with their mother to Keyhouse, their uncle’s mansion in Lovecraft, Massachusetts, after their father, a school guidance councillor, is brutally murdered by a couple of Tyler’s classmates. The entire Locke family are naturally extremely affected by the event, especially the eldest brother Tyler, who feels responsible for the event, and for not managing to rescue both his parents. Kinsey, his sister, was hiding and keeping their youngest brother Bode safe, but she’s suffering with survivor’s guilt and dealing with a sense of helplessness because she was unable to do anything but hide as the terrible events took place. She completely changes her looks and tries to stay as unnoticed as possible, refusing to make friends or connect with anyone.
Keyhouse is not your normal large New England mansion. No one really believes Bode, the youngest brother, when he says there’s a door you can go through that turns you into a ghost, or that there is a woman down the well in the well house, who speaks to him and wants to be his friend.
