There in Mayfield strange things begin to happen that lead Rob to believe his son, Jimmy, is not really dead. After a restless night and eerie dream, Rob is convinced the answer to the mystery surrounding Jimmy's disappearance and alleged death is to be found in a village called Darlington, a town found on no map. Teaming up with a quirky local waitress who insists she has been there, Shields begins his quest to find the truth about the town and his son. In Darlington, Rob and Juli come face to face with the town's secret, creatures called Darklings inhabit the night and instill paralyzing fear in Darlington's citizens. Their search for Jimmy leads them into the woods surrounding Darlington where, once in, there seems to be no way out.
