John Wayne is Capt. Jake Cutter, a Texas Ranger determined to crush a powerful outlaw gang that's selling guns to the Indians. Cutter is also trying to bring in gambler Paul Regret (Whitman), who's wanted for murder. Both missions get entangled when Cutter crosses paths with Regret unexpectedly, and the men form an unlikely friendship while Regret decides which side of the law he's really on. Co-starring Ina Balin, Nehemiah Persoff and Lee Marvin, The Comancheros is a rousing western, and the last film of director Michael Curtiz.
