Garrett is joined by a glory-seeking John W. Poe (John Beck), who works for the Santa Fe Ring. The two ride southwest to meet John Chisum (Barry Sullivan), a powerful cattle baron, who informs them that Billy has been rustling his cattle again and killed some of his men; Billy once worked for him and claimed that Chisum owes him $500 of back salary. Anticipating Garrett's arrival in Old Fort Sumner, Billy's friend Paco (Emilio Fernández) and his family leave for Mexico, soon followed by Billy. Along the way, Billy stops at the Horrell Trading Post, which is owned by an old friend. By chance, Horrell (Gene Evans) is hosting Garrett's new deputy, Alamosa Bill. After they finish eating, Billy and Alamosa step outside for a duel at ten paces, with Billy shooting Alamosa dead. Meanwhile, Garrett and Poe arrive at a saloon. Garrett tells Poe to ride on without him and that Garrett will pick him up in Roswell in five or six days. Three members of Billy's gang come into the saloon. After taunting Holly (Richard Bright) and getting him drunk, Garrett shoots him dead after he pulls a knife. He tells Alias to give Billy a message that they had "a little drink together".
