In 1998, desperate loneliness pushes preteen Amber to ignore the misgivings of her family, particularly her younger sister, when she befriends the troubled new kid in the neighborhood --- a boy with dead eyes, a fascination with fire, and no remorse. Their turbulent relationship is brief but creates lasting consequences. Twenty-two years later, in 2020, he resurfaces to kill Amber’s parents, and is in turn betrayed by his accomplice and killed in Amber's childhood home. After the deaths, Amber inherits the house and, in an effort to save money, moves in with her husband and two children, hoping to reclaim some sense of stability in the grief and chaos surrounding her. Instead, she finds that the familiar walls are haunted by more than just bitter memories and lockdown stress.

A historic hotel long past its prime and huddled along The Cut, a questionable Lake Erie beach, isn’t Sadie Miles’ ideal place to raise a toddler while also navigating her second pregnancy. After finally fleeing her abusive ex-fiancé, though, Sadie’s new housekeeping position and free room at L’Arpin Hotel are the best she can manage. On her first night, Sadie runs to help a guest struggling in the hotel’s pool only to find the water calm and empty when she gets there, leaving her with a lingering unease. When a guest then goes missing and her manager insists they simply left without checking out, Sadie suspects he’s covering up darker goings-on in the hotel. Everything isn't as it seems within the dim hallways of L’Arpin.
