Spring is a long time coming on the Great Prairie. The Sioux tribe awaits the return of the buffalo herd and is hungry. Yakari, who lives his dreams, goes with Little Thunder to look for the herd led by White Buffalo. The two friends cross a scorching desert before finding themselves faced with a wall of rocks. When Yakari climbs over the wall, he discovers green pastures where the buffaloes have taken refuge. Yakari is the first human to walk these fertile lands hidden in the desert. Knowing that the Red Men need them, the buffaloes follow Yakari.
