Forty years ago, rookie cop Bill Furman pursued suspected serial killer Arthur Blanke into the basement of Blanke's house and witnessed something that has given him nightmare his entire life.
Blanke turning into a demon and disappearing from a locked room.
Now Furman is Chief of Police and gruesome murders are once again rocking the small town of Moonrise Cove in North Carolina. Children and their parents torn to pieces. Other children missing. The crimes are eerily familiar to the ones Arthur Blanke committed. But they also seem to have something to do with Allison Navarro's family. Furman is aware Allison and her children survived an attack by a similar serial killer in Rocky Point, New York, twenty-five years ago. His suspicions about her family's involvement grow stronger when Allison's estranged son, Ken, is arrested at one of the murder scenes telling tales of a Japanese demon, the oni, being responsible.
Furman's life is turned upside down when he and Ken come face to face with the demon and he learns that it's been responsible for not just the deaths in Moonrise Cove and Rocky Point, but for hundreds, perhaps thousands, of deaths around the world. Because the oni is the Boogeyman of legend.
And it's out to finish the game it started decades ago.
