North Dakota. Present day. Haunted prairies and shimmering badlands, ghost towns and grazing buffalo. Lakota, Sioux, Chippewa. Indian country now buried under Wal-Mart and strip malls. Vietnam vet turned horse rancher Leo Kuntz feels the quiet storm of change. He has fought to preserve the sacred lineage of Sitting Bull's Nokota horses for decades. It has impacted his life, his loves and the very beating heart of him. But the 21st Century is upon us now. America's frontier is vanishing hard and fast and so too are the old ways, people and cultures. In the face of such stark transition Leo may be the last of his kind. His struggle to save the equine legacy of the greatest American Indian of them all is running out of time. Nokota Heart is his story.
