Armed with his uncle's knowledge of horse ranching, the land his grandfather has willed to him and his great red stallion, Washington "Wash" Ross heads to Wyoming.

Wash begins to believe he can breed his great horse with the wild mustangs of these prairies when he sees the rolling hills and rich grasses of the land his grandfather settled. But the beauty of the West also holds danger and violence for a tenderfoot like Wash.

When the corrupt and controlling Whelper brothers threaten to destroy his plans, Wash is forced to take up a gun and fight for his land, his rights and his dream.
