In 1870 Mexico, wounded gunman Steve Fallon takes refuge at the ranch of ex-Confederate officer Mike Summers and his wife, Franchea. A romance develops between Fallon and Franchea's sister, Juana. Ortega, a ruthless landowner, is trying to take over all the ranches in the valley, by force if necessary. Any resistance is eliminated by his henchman, Danny Post, and his gang of mercenaries. Upon learning that Summers refuses to carry a gun because of all the bloodshed he saw in the Civil War, Fallon decides to stay and help put an end to Ortega's reign of terror. When Danny tries to collect "protection" money from Summers, Fallon disarms and thrashes him. After a second meeting with Fallon, in which three of the mercenaries are killed, the cowardly Danny leaves town. Ortega and the remnants of his gang then raid the Summers ranch and leave Fallon with his hands crippled. Believing Fallon dead, Danny returns, kills Ortega, takes over his holdings, and then proceeds to the Summers ranch. When he sees the helpless Fallon, he draws his gun, but Summers appears and shoots Danny to save his friend's life. Fallon decides to settle down with Juana.
