Upon Winona's promise to wed the avenger of her brother's death, Antelope and Red Owl, rivals for her hand, set forth on their mission. Later, Red Owl's cowardice causes him to flee when Winona is captured by the renegades who have slain her brother. Antelope engages the slayers, however, and kills them single-handed, although it apparently costs him his life. Winona spurns Red Owl, who asks her to be his squaw, declaring herself to be Antelope's widow, in accordance with the terms of her promise. Antelope is not dead, however, and Winona later becomes his bride.
