In the small town of Dittmer, MO, a group of friends goes to the lakeside home owned by Gary, the uncle of one of them, to help clean out an old shed, but what they don't know is that the property sits on an old Indian burial ground. Gary tells the kids the story of the agony and death of the Trail of Tears, and a Cherokee elder (Wes Robertson) who used black magic in an attempt to help his tribe. The elder was consumed by the evil spirits and turned all the crops to stone. As punishment, he was thrown into a spring-fed hole and covered with rocks, which a recent flood has washed up. These rocks contain demonic spirits, and the legend goes that when a descendant of the elder comes to the land, the demons will arise and possess the living. None of the kids are Cherokee, but one of them had an accident requiring a blood transfusion some time before. Pretty soon, the kids start becoming possessed, grow giant sharp fangs, and the blood starts flowing as the evil dead rise to claim their victims. There's a screwdriver in the head, a demon stabs a kid in the neck with his venomous spiked tongue, throats are ripped out with clawed hands, a zombie is crushed with an old refrigerator, a head is blasted apart with a shotgun at close range, a chainsaw dismemberment, a shovel in the chest, a smashed skull, an electrocution, and a girl is completely torn in half and gorily cannibalized. Eventually, the elder returns through a spiritual barrier as a horned demon named Retlawkoob (Jerry Bates), and that's when the surviving kids really have their hands full.
