After an army transport vehicle loses its poorly secured cargo of nuclear waste, a family of illiterate moonshiners fails to take heed of the warnings printed on the side of the barrel and proceeds to use it to cook up a batch of sour mash. The brew is a foul-tasting, lime-green concoction, but it doesn't prevent the entire town from imbibing, and as anyone who's studied nuclear science or watched horror films knows, the inevitable result is a rampage of cannibalistic zombies. Luckily for the hungry population, there's a group of city folk camping near the still who are ripe for the picking. After losing a few companions, the campers discover that a certain brand of deodorant might be their only hope for survival.
