Green Grass of Wyoming (1948): Cast & Plot

Beaver Greenway, Charles Coburn, is furious when Thunderhead, the white stallion that Ken McLaughlin Robert Arthur freed years earlier, steals another of his mares. Rob McLaughlin, Lloyd Nolan, organizes other ranchers to hunt Thunderhead, who, like his great-grandsire the Albino before him, has taken mares from local ranches. Meanwhile, Ken McLaughlin returns from a horse-selling trip with profits that he uses to buy Crown Jewel, a trotter, and though Rob is skeptical at first, he eventually agrees to train the mare for harness racing. One night, Thunderhead appears again and runs off with Crown Jewel. The next day, Rob leads a search party to locate them and shoots Thunderhead, though Ken is determined to save him.
