In a connected universe, vandalism and strange noises cause fear and unrest in a small Midwestern town. Unexplained knocking on windows is coming from outside by an unseen perpetrator on a nightly basis. Crops are being damaged. Animals are disappearing. Mary, a local police officer, is put to the task of solving these mysterious disturbances while attempting to overcome tragedy in her recent past. She must also keep those she loves safe-namely, her husband, Ted, who works the night shift at the manufacturing company outside of town, and her elderly neighbor, Edna, the one-woman neighborhood watchman. It isn't long before Edna and Mary begin to experience what the locals are talking about as the unexplained events have moved into their quiet neighborhood near the edge of the town. As Mary investigates the incidents, she discovers a potential link-symbols painted or carved near the victims' properties. As the investigation unfolds, Mary encounters a new stranger in town, Webb. Her instincts tell her that he has something to do with the events. It doesn't take long for Mary to realize that her intuitions are correct when she learns that Webb has a history of dealing with unexplainable phenomena. Are the symbols, noises, and vandalism connected? What role does Webb play in the increasing activity? Will her small town ever be the same again?
