When an Apache chief is killed in a fight with a settler, his son goes on the warpath, launching an attack on a supply train headed for Fort Yuma. The only survivors - an embittered officer, a scout and a female missionary - realise the war party plan to kill everyone at the fort, and face a tortuous journey to raise the alarm. Western, starring Peter Graves and Joan Vohs.

Apaches plan to attack a fort by wearing uniforms plundered from a cavalry officer's (Peter Graves) supply column.
