In 1870, when white men and Indians are fighting bitterly, Tom Jeffords (Stewart) strongly believes the Apaches are treated unfairly. After befriending their leader Cochise (Jeff Chandler) and arranging a truce, he is called upon by a U.S. Army general to negotiate a government peace treaty. Though he fulfills his mission, Jeffords soon experiences great tragedy when he, his Indian wife (Debra Paget) and good friend Cochise become targets of a renegade ambush.
