Clumsey easterner Mickey Rooney travels to Mexico to make a surprise visit to older brother Robert Stack, only to discover he's a smooth-talking, black-hearted under boss to a bandit that's terrorizing the locals and robbing banks north of the border. Trouble arises when he inadvertently brings along Texas Ranger Robert Preston.
Despite the movie being a fairly straight-faced affair, Rooney plays like it's a comedy most of the time. Meanwhile, Stack is dead serious and seriously mean, prompting one of the characters to suggest that he's possessed by evil spirits! The combination of the two actor's performances make the film seem pretty odd.
On the whole though, this is an entertaining adventure, with some good suspense scenes, as well as nice, picturesque Mexican scenery and decent production values.
Also, there's a neat psychological twist in the final scene. Maybe Stack is possessed after all.
