Following their honeymoon, Lucas and his new wife Abigail are invited by his mother Deborah to stay at her summer home, a cabin in the woods, for the weekend. While there, they suddenly find themselves under attack by a cult of religious zealots, led by Abigail's estranged father Jacob and uncle Noah, who secretly witnessed her and Lucas eloping and are driven to madness by what they perceive to be sinful. Together, the three must fight like hell to survive the night.
