Set near the cursed Hellfrozeover Lake, the story centers on Billy Bob (Zachary Chambers), a reclusive and mentally impaired man who stalks young campers engaging in premarital sex. Raised by his puritanical and deeply traumatized mother (Belinda Soprano), Billy was taught that sex is evil and that his disability is a divine punishment for his mother’s own non-consensual encounter with a family member.
