A young boy's disappearance from the sleepy southern hamlet of Niceville sets off a series of events that will ultimately expose the dark secret festering below the town's pleasant exterior. One fine spring day in Niceville, a leafy village in the Deep South, a young boy named Rainey Teague disappears on his way home from school. What makes this event even more disturbing is that he seems to have literally disappeared - security camera footage captures the moment of his instant, inexplicable vanishing. The search for the boy is led by ex-Special Forces veteran Nick Kavanaugh, now a detective with the local police and no stranger to lowlifes and their criminal hijinks. In the nightmare time that follows Rainey's disappearance, Nick and his wife, Kate, a family practice lawyer, find themselves drawn into a shadow-world between life and death where they ultimately make the discovery that what lies beneath Niceville is a malevolent power, darker and older than the ancient mountain forest surrounding its source: a 1000-foot-deep pit known as Crater Sink.
