Plot In Montana in 1882, "Boss" Spearman is a seasoned open range cattleman, who, with hired hands Charley Waite, Mose, and Button, is driving a herd cross-country. Charley is a former Union soldier who served in a "special squad" during the Civil War and feels immense guilt over his past as a killer of both enemy soldiers and civilians. Boss sends Mose to the nearby town of Harmonville for supplies. The town is controlled by ruthless Irish immigrant and rancher Denton Baxter, who hates open-rangers for using his land to feed their herds. Mose is badly beaten and jailed by the town's corrupt marshal, Poole, after defending himself in a fight with some of Baxter's men. The only Harmonville inhabitant willing to openly defy Baxter is Percy, the livery stable owner. Boss and Charley become concerned when Mose does not return. They retrieve him from the jail but not before Baxter gives them an ultimatum to leave the area before nightfall. Mose's injuries are so severe that Boss and Charley take him to the local physician, Doc Barlow. There they meet his assistant, Sue. Charley is attracted immediately but assumes that Sue is the doctor's wife and chooses not to stay the night even after being invited. After catching masked riders scouting their cattle, Boss and Charley sneak up on their campsite, disarm, and humiliate them. At the same time, other riders trash their camp and shoot Mose and Charley's dog Tig dead. Button is badly injured after being shot in the chest. Charley and Boss vow to avenge their friend. They leave Button at the doctor's house and go into town; with help from Percy, they capture Poole and his deputies, subdue them with chloroform stolen from the Barlows, and lock them up in their own jail. Charley learns that Sue is the doctor's sister, not his wife. He
