The entire area is shaken by horrific events that took place at the “Tower” motel. A woman named Amy brutally killed her family and then took her own life, leaving behind a mysterious inscription on an old photograph of her mother: “29 rooms.” The only survivor is her little daughter, Lou, who managed to escape through a window and hide on the roof.
The investigation is taken up by Jason Hawke. His wife, Margo, and her sister Piper were friends with Amy in childhood. They loved playing at the “Tower” motel, where there were always 28 rooms. Jason feels this isn’t a coincidence, and soon begins to suspect that Margo and Piper are hiding something.
