Cast & Crew
While investigating his latest case, Texas Ranger Sgt. George Standish finds himself near his ranch, and decides to spend the night there. Before his wife and son retire for the evening, however, a gang of bandits arrives, and George, unaware of their criminal ways, grants them permission to camp on his property. That night, the careless bandits ignite the ranch house, killing George and his family. Sometime later, George's brother Bob, who also works for the Rangers, is assigned to the case and reports to headquarters. There, Bob learns what he can about the prime suspect, Mungo, who is believed to be the leader of a gang of outlaws. Despite the fact that his jurisdiction extends only to the border, Bob crosses into Mexico in search of Mungo. After adopting the alias "Bob Carver," Bob boards a stagecoach carrying banker Horace Randolph. Just as Randolph is telling the other passengers, Priscilla Weeks and her niece, Ellen Reed, that their stage is carrying $12,000 in silver and gold, they are held up by two bandits. Bob shoots both bandits, then goes to the jail to inform Sgt. Carlson that he has killed notorious outlaw "The Rio Kid" and his partner. Later, Bob decides to impersonate The Rio Kid and enters José's bar. Outside José's, Bob meets Priscilla and Ellen, who invite him to dinner. After introducing himself to "Hungry" Hank, one of Mungo's henchmen, as the Rio Kid, Bob tells him that he is looking for some men to add to his own gang. Later, Hungry leads Bob to Mungo's hideout, but when Bob sees the men, he tells them that he does not believe that they are tough enough to join up with his gang. This angers the outlaws, who try to grab Bob, but he escapes. In town, Bob informs the gang that Randolph is expecting $200,000 to arrive soon at Stockman's Bank in El Paso. Bob tries to reveal his true identity to Ellen, but she remains convinced that he is actually The Rio Kid. Later, the gang takes their newest recruit, a young man named Tommy, back to their camp where one of the outlaws tests his mettle by threatening him with a hot branding iron. Bob, who has followed behind, quickly takes aim, shooting the branding iron from the outlaw's hand. Back at Stockman's Bank, Bob learns that the gang has planned to kill him and Tommy immediately following the robbery. Suspecting that he is in danger, one of Bob's friends, Gans, rushes to José's to look for him. Meanwhile, the gang crosses the border into Juarez, arriving at José's a few minutes later. Bob then arrives just as Hungry knocks Gans from his horse. After the ensuing brawl, the bandits are arrested and taken to jail. The next day, Priscilla and Hungry flirt with one another, while Bob rides off to his next assignment.
