While pursuing marauders on the Mexican side of the Rio Grande, Col. Mackenzie is severely wounded in an ambush. He manages to escape back to the homesteads dotting Texas' Chuma Valley, where the ranchers hide him from the outlaws seeking to finish him off. Mackenzie recovers sufficiently to lead the Texans in an inspired counterattack against the brigands.
