Twenty-two years later, 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 moves in with her husband and two children. She finds that the familiar walls are haunted by more than just bitter memories and lockdown stress. Although she tried to brush off the strange happenings as stress-fueled hallucinations, Amber is soon forced to admit that something much more real haunts her family. But Amber has deadly secrets of her own, and she must resolve these long-buried truths or lose the life she’s contrived for herself.

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.
