Bryan and Ellie Stockton hope they left behind their demons when they move to their idyllic new home in southern West Virginia. Above all, they want a fresh start for their young son, Derrick, who witnessed the tumultuous first years of their marriage—years that were rife with substance abuse, rage, and resentment. Their bright hope for the future is darkened when a child disappears from their neighborhood. The couple becomes suspicious of a reclusive resident with a degenerative brain disorder. Strange events begin to happen in their house just as Derrick tells them about a new friend who visits him at night. Their son may be acting out from the trauma he endured, or he could be the obsession of something much more sinister.
