When she was nineteen, Rita Mason moved out of her mother's home and into the Avalon Motel. She needed some time away and planned to stay there for the summer before leaving for college in the fall, but nothing prepared her for the horrors in store. Once living at the Avalon, Rita started having dreams about a mysterious tunnel. The dreams got worse, revealing piles of bones and even a young blonde woman, apparently murdered at the motel. Eventually, Rita left the Avalon, and her dreams remained a secret from everyone but her boyfriend, Keith. Still haunted by questions, Rita tried to move on with her life, but following Keith's death, she feels an urge to return to the Avalon and discover its secrets. It has been five years since she set foot on the property, but she is now back with a mission. She hopes to unravel the mystery of the tunnel and reveal the identity of the blonde woman from her dreams. But dealing with the dead is never easy, especially when there might be a mass murderer still on the loose who would prefer to keep Rita quiet at any cost.
