A drifter sets out on an epic journey to avenge the death of his cavalryman brother, but rather than target the Apaches who killed him, he vows to go after the gang who supplied them with their weapons - leading to conflict with the sadistic son of an elderly rancher. Anthony Mann's Western, starring James Stewart, Arthur Kennedy, Donald Crisp and Cathy O'Donnell.

Will Lockhart arrives in Coronado, an isolated town in New Mexico, in search of someone who sells rifles to the Apache tribe, finding himself unwillingly drawn into the convoluted life of a local ranching family whose members seem to have a lot to hide.
