A series of devastating solar flares hit the Earth, disrupting the magnetic field and causing a worldwide drought. Soon, governments are unable to provide for their citizens, which results in chaos. In the wake of this disaster, a man wakes up outside White River, a small town in Arkansas. He has no memory of who he is, or where he comes from. Barely alive, he stumbles into the town, and is found by the town Sheriff, and her sister, Linda Carter. After the town turns against the stranger, she offers him a place to stay on her small farm outside town. On the farm, he discovers water, which enables them to grow their own food, and supply the town with water. They soon realize that they have to protect the food, water, and people against murderous raiders that now roam the lawless land. When Linda is kidnapped by a group of raiders, the stranger shows his true colors and abilities. With the help of his new friends, he has to attempt the rescue of the woman he loves.
