Joe is stranded in the desert when his mare falls and breaks her leg. He falls unconscious from exhaustion and lack of water, and is found near death by a Paiute named Swift Eagle. But instead of saving Joe, Swift Eagle steals his gun and goes back to the reservation. His grandfather, Chief Red Cloud, finds the gun and insists they return it and help the owner. Red Cloud cares for Joe until he gets his strength back and then orders Swift Eagle to take Joe into town.

In town, Joe meets the most powerful man there, Frank Ryan, who showers Joe with hospitality. Joe feels indebted to both Red Cloud for saving his life, and to Frank Ryan for extending hospitality in an unfamiliar town. So when Red Cloud challenges Frank to a fight to the death, Joe tries desperately to keep the peace. The reason for the fight? Fifteen years ago, Frank took Red Cloud's warbonnet, and has been proudly displaying it ever since, on the wall in his saloon. Red Cloud, now an old man, must regain his honor before he dies.
