One evening John Tunstall and the Regulators go into town for a New Year's dance. John asks Alex, who is with Susan, if he could get him an appointment with the governor, but Alex tells him L.G. Murphy already bribed the governor. Doc Scurlock dances with and tells Yen Sun a poem he wrote and after Murphy leaves with her, Alex tells Doc that Sun's family ruined one of Murphy' shirts and he took her as compensation. After John's funeral, Alex convinces Justice Wilson to deputize the Regulators. Later, William H. Bonney gets his photo taken and then gives it to Alex, who is upset with him and tells him that the Federal Government now has a bounty on him. Susan tries to convince William to go to Mexico, but he and the Regulators just toss away their badges.
The Regulators arrive at Alex's home and the house is soon surrounded by Peppin, John Kinney and Dolan's posses. Alex tells William that he thinks Pat Garrett set them all up for a trap. Kinney tells William and the other Regulators to surrender. William calls Kinney a bastard and the posses shoot at the house. William calls out to Peppin and asks him if Charlie Crawford is with them and then shoots Charlie dead. The posses unload on the house once more and evening and night pass without incident. The next morning, the U.S. Cavalry arrive with Colonel Dudley. Murphy yells at Dudley to burn the house down. The cavalry troops start shooting at the home and Murphy's posse starts the house on fire. Alex has Susan leave and as she walks by Dudley, she slaps him and calls him an animal. The Regulators run out of the house and start shooting at the troops and Alex is killed by a Gatling gun.
