The grassy Great Plains shake with thunder and deadly tornadoes whirl down from storm clouds as the First Americans begin the battle the will determine which peoples--the savage or the gentle--will shape the future or humankind. On one side is the young shaman Cha-kwena, who has led his tiny band along the trail made by a magnificent white mammoth, the totem he believes will lead the People to a land of safety and abundance.
