During a severe dust storm, ex-Ranger Jingle takes refuge at the Rivers ranch, where he is befriended by the owner, Buck Rivers. Jingle helps Buck and his younger brother Babe, who is also half-owner, herd their cattle down to the valley, where Babe is left in charge of the herd. Gambling house proprietor Jack Keeler convinces Babe to sign a bill of sale for the herd to repay a gambling debt, by promising him that Buck will think the herd was rustled. Buck discovers the crooked sale, however, when he later tries to take a loan against his herd. Buck receives a letter from stagecoach driver Jim Bradshaw informing him that Babe is in deep with the Keeler gang in Pecos, and may be in trouble. Buck and Jingle head down to Pecos to retrieve Babe, but on the way find that Jim has been mortally wounded during a stagecoach robbery perpetrated by the Keeler gang. A deputy sheriff arrests Buck and Jingle because he finds them at the scene of the crime, but they are released after Sheriff Rocky Ellsworth recognizes Jingle as an old friend. Hoping to save Babe from the posse, Buck and Jingle follow the men to the Keeler hideout, where Buck creates a diversion that leads away half of the posse. Although this allows some of the bandits to escape, Babe is captured and put in jail. Buck learns of a plan to lynch Babe, and in disguise, helps him escape from jail. They are nearly caught by Bradshaw's daughter, Ruth and Keeler, who is romancing Bradshaw's other daughter Marge, shoots Babe as he makes his escape. Buck takes Babe to a hideout, and before he dies, Babe reveals the hiding place of the $50,000 in gold stolen from the stagecoach. After mournfully burying his brother, Buck goes to find the gold, but discovers that the chests are filled with scrap metal. He is accosted by two of Keeler's confederates, Blacky Bates and Davilla, but after convincing them they have been double-crossed, captures them and ties them up in their cabin. Back in town, Rocky stays the lynch mob by telling them he has relocated Babe, even though he knows Babe escaped. Jingle takes Wallace, who organized the lynch mob and helped with the robbery, hostage, and forces him to write a confession. In the meantime, Buck releases Ruth from a closet that Keeler locked her in after running away with Marge and the gold. After a long chase, Buck is shot by Keeler, but returns fire and kills the outlaw. While Marge mourns over her lover, Ruth changes the spurs from Buck's boots to Keeler's, because they are the only things that can identify Buck. She and Rocky immediately take Buck to the doctor. Buck recuperates from his injuries under Ruth's loving care.
