After his employer is murdered by rival cattlemen, a troubled and uneducated young cowboy vows revenge on the murderers.

William Bonney - Billy the Kid - gets a job with a cattleman known as 'The Englishman,' and is befriended by the peaceful, religious man. But when a crooked sheriff and his men murder the Englishman because he plans to supply the local Army fort with his beef, Billy decides to avenge the death by killing the four men responsible, throwing the lives of everyone around him - Tom and Charlie, two hands he worked with; Pat Garrett, who is about to be married; and the kindly Mexican couple who take him in when he's in trouble - into turmoil, and endangering the General Amnesty set up by Governor Wallace to bring peace to the New Mexico Territory.—Gary Dickerson <[email protected]>

While wandering in a desert area with the saddle of his deceased horse on his back, the drifter William "Billy the Kid" Bonney stumbles with the cattle owner John "The Englishman" Tunstall that asks him what he wants and William asks for a job. Tunstall hires him to help to bring his cattle to Lincoln to sell the herd to the army and William befriends him. However, the local Sheriff Brady ambushes Tunstal with the rancher Morton, his Deputy Moon and Hill, and kills the cattleman to avoid the business and steal his herd. Billy the Kid promises revenge against the men and, together with his friends Charlie Boudre and Tom Folliard, he kills Brady and Morton. Billy hides at McSween's house that is burnt down to ashes and Billy is assumed dead by the population. He flees to Madeiro where he meets his friends Pat Garrett, Saval and his daughter Celsa who loves Billy. Soon Governor Lew Wallace proclaims amnesty in the New Mexico Territory and Billy is free from any charge. However, Moon and Hill are still alive and Billy still wants to avenge his friend.—Claudio Carvalho, Rio de Janeiro, Brazil
