Cast & Crew
Texas Ranger Sergeant Buck Weaver and his men ride out to help the crew at the Allen Spencer ranch save their herd of cattle from a gang of outlaws. Afterward, Buck meets Spencer's niece, Helen Clifford, and they are immediately attracted to each other. When Buck and fellow ranger Jack accompany a shipment of silver, they are attacked and Jack is killed. Upset at the loss of the silver, Spencer talks to Ranger captain Moore, who blames Buck and expels him from the service. Buck leaves for Mexico, where he meets Rosa, a dancer who is also the girl friend of a gangster, Quinn. Soon, Buck and Quinn are fighting, and after Quinn subdues Buck, he takes him to see bandit chief El Coyote, who remains hidden behind curtains during their entire meeting. The next day, Buck leads the bandits in the holdup of a silver shipment. Later, Buck meets secretly with Moore, whose dismissal of Buck was only a ruse, to advise him on their undercover operation, but Quinn, who is unaware of what the rangers are up to, has put a price on Buck's head. When Helen and ranger Flaherty try to warn Buck of the danger, they are taken prisoner. Quinn, identifying himself as El Coyote, enters the Spencer mine to confer with Spencer, who is the mastermind of the operation. Buck soon enters the mine, and after releasing Helen and Flaherty, he engages in a shootout with Quinn and Spencer. After Quinn is shot, Buck lures Spencer into the open by pretending to be out of ammunition, then captures him.
