Oregon territory 1868: Indians of many tribes trust Sgt. Emmett Bell, who rides into Dr. Joseph Holden's mission with his Indian scouts. However, troop and weapon movements by new U.S. Cavalry commanding officer Col. Steadlow have endangered the peace and angered the chiefs, in particular one called Kamiakin. An outraged Bell tries to appeal to Steadlow as well as Capt. Tom Gaxton, whose wife Calla was once in love with him. Calla and another woman are taken captive but are rescued by Bell, rekindling his and Calla's romance.
