King of the Mustangs Reigns Over Idaho Oregon Canyons
Rainbow, 1 200 pound stallion, leads a herd of 4 000 wild horses along the Owyhee River on the Idaho Oregon border. Ranchers aim to recapture the land as Rainbow defends Stardust and the herd against hunters, airplanes, and rival stallions. Rainbow has become a legendary figure among locals in Boise and Jordan Valley while claims of duels and battles surround his reign.
