Oil City, PA is a small town with a big history. Once a crucial center for America’s steel and petroleum industry, it’s now a shadow of its former self. While life for the 10,000 residents can be tough, it’s a simple place where bad things rarely happen and people watch out for one another. In 1992, when an 11-year old girl goes missing on her way home from a Halloween party, it shocks the close-knit community. When it becomes clear a terrible crime has been committed, suddenly the trusting town realizes that monsters exist. For years, police search for clues to try to unmask the evil they’re certain lives among them in order to bring justice to the victim and closure for her family.
