In 1872, veteran Indian fighter Johnny MacKay (Alan Ladd) is sent for by then President Grant (Hayden Rorke). He tells government officials in Washington about hostilities between settlers, soldiers and Modoc renegades near the California and Oregon border. He is appointed peace commissioner for the territory.
On the way west, Johnny gives an escort to Nancy Meek (Audrey Dalton), a retired army colonel's niece. Nancy is traveling to a ranch owned by her aunt and uncle. There is an ambush outside Sacramento during which the sweetheart of their stage driver Bill Satterwhite is killed by a Modoc renegade. Later they find Nancy's aunt and uncle murdered and the ranch burned.
The grown children of an old Modoc chief, Toby (Marisa Pavan) and Manok (Anthony Caruso), meet Johnny at Fort Klamath. They tell Johnny it is a chief who calls himself Captain Jack (Charles Bronson) and a band of renegades who are responsible for the brutality while most of the other Modoc wish to live in peace. They both served as intermediaries for the Modoc.
Toby and Manok take Johnny and others to a peace talks near Lost River to discuss violations of the peace treaty signed by the Modoc in 1864 in hopes of bringing about peace again. When the violations are being discussed between Johnny and Captain Jack a vengeance crazed Satterwhite (Robert Keith) opens fire and kills the brave who killed his woman. A rampage results in which the renegades massacre 18 settlers. The Army responds but is unable to dislodge the renegade Modoc from their mountain stronghold and are forced to retreat with several casualties. After hearing of the massacre and the Army defeat President Grant orders General Canby's to act as a defensive force only.
Once more peace talks were arranged but Toby and Manok warn of treachery. General Canby (Warner Anderson), Dr. Thomas (Richard Gaines), a Modoc sympathizer, Johnny and friend Mr. Dyar (Frank Ferguson) are to come unarmed but Johnny and Mr. Dyar come armed with revolvers hidden under their shirts. During the negotiations Captain Jack pulls a hidden revolver and kills the General as other Modoc pull theirs and start firing. Dr. Thomas is also killed. Johnny is shot but only wounded and unconscious and is about to be scalped when Toby tries to shield him from harm and is killed. Mr. Dyar escapes in a hail of bullets. The Army responds causing Captain Jack and the other Modoc to retreat back to their stronghold before Johnny can be killed.
President Grant is forced to act because of the public outcry and orders Johnny to do whatever is necessary to bring Captain Jack to justice. The renegades are eventually dislodged from their stronghold and are forced to split up into separate groups. Soon most of the Modoc surrender leaving Captain Jack to survive on his own. He and Johnny have a shootout and hand-to-hand combat. Johnny prevails and places him under arrest. Captain Jack is jailed, put on trial and sentenced to hang. Afterwards Johnny returns to the woman he has fallen in love with, Nancy.
