Set in the southernmost regions of Texas, Ride, Vaquero stars Robert Taylor as a steely-eyed gunman named Rio. In league with Mexican bandit Jose Esqueda (Anthony Quinn), Rio participates in the sacking of Brownsville. Only one man seems to have the intestinal fortitude to stand up to the villains: homesteader King Cameron (Howard Keel), who's already been burned out of one home by Esqueda and doesn't intend to allow it to happen again. Cameron's wife Cordelia (Ava Gardner) stands by her husband, which of course puts her in harm's way when Rio sets his romantic sights upon her.
