Six troubled high school students and their chaperon, an optimistic youth ministries Pastor, return from an outdoor character building retreat in the mountains. During a raging storm, their bus crashes, hopelessly stranding them in the middle of the Trucker's Triangle, a forgotten locus of consummate evil in the middle of nowhere. The hapless group seeks shelter for the night in a seemingly abandoned trailer park they find down the road. However, when the sun sets, it's not refuge they find. Instead, terror finds them in the form of Norma, a damned redneck reaper with a killer body who dispenses vengeance and death aided by her cursed companions, a bloodthirsty brood of undead trailer trash.
