Set in the 1980s, an estranged family hires a cult deprogrammer to take back their teenage son from a murderous cult, but find themselves under siege when the cultists surround their cabin, demanding the boy back. A young man, Justin Powell, is held up at gunpoint by two ski-masked men and dragged back to a secluded cabin. This isn't a standard kidnapping, as Justin's estranged family is at the cabin waiting for him. Composed of Justin's father Andrew, mother Kathy, brother Campbell and former girlfriend Samantha (who has recently given birth to their child), Justin's family is dedicated to freeing him from the brainwashing he has undergone at the hands of a vicious cult. With the help of Jimmy Levine, an experienced cult deprogrammer, the family does their best to bring Justin back to reality. Everything goes awry when the cult (a murderous gang of masked men and women known as the Jackals) descends upon the cabin, demanding Justin back. A vicious battle unfolds, testing familial loyalties and unleashing a bloodbath in which there are few survivors.
