Texas Rangers is a 2001 United States drama/western film directed by Steve Miner. It is about a group of Texas Rangers set in the post-American Civil War era. Ten years after the Civil War has ended, the Governor of Texas asks Leander McNelly (Dylan McDermott) to recommission a company of Rangers to help uphold the law along the Mexican border. Aside from a few seasoned veterans, the recruits are young men who have little or no experience with guns or policing crime. The antagonist of the story is John King Fisher (Alfred Molina) who is stealing cattle from Texas cattle barons like Richard Dukes and Victor Logan and driving them into Mexico, where he sells them to the Mexican army. After McNelly and his men pursue Fisher for a while, they fall into a trap, where many of the young and ill-trained Rangers are killed. Defeated and low on morale, the men fall back to a ranch house and attempt to set up an ambush for Fisher. After being double crossed by a woman (perhaps unwittingly), the rangers remain one step behind Fisher and his men. Two of the Rangers follow Fisher and his men to the Mexican border, where they wait for the rest of their company. Once the entire Ranger force arrives, they plan their final attack. In a final gun-slinging showdown, the Rangers face off against Fisher and his men that will either tip the state of the border country in the direction of either chaos or justice.
With origins dating to the earliest days of Anglo settlement in Texas, the Texas Rangers form the oldest law-enforcement agency in North America with statewide jurisdiction. They often have been compared to four other world-famous agencies: the FBI, Scotland Yard, Interpol and the Royal Canadian Mounted Police. Scores of books, from well-researched works of non-fiction to Wild West pulp novels, have been written about the Rangers. They are part of the history of the Old West, and part of its mythology. Over the years, a distinct Ranger tradition has evolved.
