Jim Benton has been too busy making money to learn to read and write, but he persuades Evelyn Hastings to open school on his ranch and he is her most devoted pupil. The sheepmen carry out their threat to cut off Benton's water supply and Evelyn makes him promise to shoot only in self-defense. He keeps his promise, but still he has to kill, and a packed jury of sheepmen bring in a death verdict. The cattlemen attempt a rescue, but it is Evelyn who saves the day.
