Ride, Vaquero!

After the Civil War, King Cameron (Howard Keel) moves to Texas, purchases a cattle ranch and settles down with his wife, Cordelia (Ava Gardner). They find themselves at the mercy of Jose Esqueda (Anthony Quinn), a local bandit who has terrorized the town with his adoptive brother, Rio (Robert Taylor). Rio is kidnapped when he tries to mount an attack on the ranch and agrees to work for Cameron so he can be close to Cordelia. Though he's incensed at Rio's betrayal, Jose vows to get him back.
