Following a bank robbery in the American West, the partner of Scottish outlaw Arch Deans is killed and his young
Kiowa half-breed friend Billy Two Hats is captured. While Billy is being transported, Deans gets the drop on Sheriff Henry Gifford at a remote trading post, enabling Billy to escape. As they flee, the sheriff's friend, the trading post owner named Copeland, takes down his old, long-range
buffalo rifle and fires a shot that kills Deans' horse, breaking his leg. Billy builds a
travois on which Deans can ride, dragged behind Billy's horse. Deans and Billy encounter trouble on the trail, four Indians demand whiskey from them, but Billy talks their way out of it. Billy and Deans encounter Spencer and his wife, Esther, at their remote homestead. Deans persuades Spencer to take him in his wagon to get horses on the condition that Billy stays with Esther to protect her and the homestead from marauding Indians. Billy is also to keep a lookout for the pursuing Gifford. Billy and Esther spend their time together talking and developing romantic feelings for each other. Esther, a young
mail-order bride from the East, is unhappy with her older, abusive husband. She falls in love with the young, good-looking Billy. Gifford finds the two in bed together, assumes Billy raped the woman, becomes enraged, and beats him. Esther attempts to explain, but cannot because she stutters uncontrollably when distressed. Deans and Spencer encounter trouble on the trail, the four Indians who demanded whiskey from Deans and Billy earlier, ambush their wagon in a canyon, killing the horse and besieging them. Spencer is killed. Gifford, Esther, and Billy then set out after Deans. They find Deans near death. With Esther's help, Billy kills Gifford. Deans dies of his wounds. Not believing in burying the dead, Billy places his body in a tree atop a hill, Indian fashion. Esther and he ride off together. ==Cast==
