The story follows the Seversons, a family starting fresh in a quiet suburban neighborhood, whose next-door neighbors, the Kringles, celebrate Christmas year-round. What begins as charming quickly turns unsettling, as Mark and Julie grow concerned about their son’s growing attachment to the family. After a heated confrontation, Mark heads next door to bring his family home only to uncover the Kringles’ true intentions: to hypnotize and indoctrinate them. What follows is a life-or-death rescue mission, as Mark teams up with a rogue, badass Santa in a high-stakes, action-packed fight to save his family.
