Jack Rance and Bess Shackelton, an engaged couple, are part of a party of settlers, moving westward. The settlers' camp near a band of Sioux Indians. Chief Eagle is picking herbs when he sees the wagon and prairie schooners in the valley below. As he hastens to his tribe, the bridle rein breaks, and Eagle is thrown and badly injured. He is found by his devoted squaw, but she cannot lift him. Jack and Bess are out riding. They come across Eagle and Dark Feather, and, seeing his bad plight, lift him on his horse and take him back to their camp and attend to his injuries. Dark Feather, believing that Eagle is being taken a captive, rides into the Sioux camp, and gives the alarm. The Sioux thereupon ride swiftly to the settlers' Camp and attack it. Eagle hears the war whoop, and, crawling painfully from his packet, he makes himself known and stops the attack. During the short fight, a half-breed steals through the wagon lines, and attempts to abduct Bess, but Eagle appears and commands him to go. Jack and Bess go to get water, the olla breaks, and Jack returns to camp to get another, leaving Bess to await his return. Boyd and two Indians find her and ride off with her, but they are seen by Dark Feather who gives the alarm. Eagle overtakes the half-breed, who transfers Bess from his horse to one ridden by one of his Indians. He and Eagle fight on horseback and the half-breed falls. Jack and several Indians intercept the half-breed's companions and rescue Bess and take the abductors prisoners. Eagle and Dark Feather ride to the settlers' camp with Jack and Bess, and are amply rewarded with a big dinner.
