Plot

In Lincoln County, New Mexico, English cattleman John Tunstall hires a wayward young gunman named William “Billy the Kid” Bonney to join the "Regulators" who lived and worked on his ranch: Doc Scurlock, Jose Chavez y Chavez, Dick Brewer, "Dirty" Steve Stephens, and Charlie Bowdre. Tunstall tries to educate and civilize the young men in his employ, and clashes with rival rancher Lawrence Murphy, a well-connected Irishman in league with the corrupt Santa Fe Ring.
