Buffalo Gun

In 1875, in Western Indian Territory, government agent Webb Pierce and deputized partners Marty Robbins and Carl Smith go undercover as cowhands escorting a herd of government-supplied cattle to the Cheyenne reservation. Webb, Carl and Marty are in search of a stash of valuable buffalo guns, known as the "Big Fifty," which were stolen from a military convoy en route to a nearby Army post. Webb believes that a recent spate of cattle rustling and the thefts of the rifles are connected, and are being used to foment a war among the various tribes. The rustlers, secretly led by corrupt government Indian agent Rocca, include many men from the nearby town of Las Cruces, including merchant Bert Murdock and telegraph operator Vin Miller. Just outside the Cheyenne reservation, the rustlers attack Webb, Marty, Carl and the herd. When a renegade Indian with a powerful rifle shoots at him, Carl chases his attacker and seizes the gun, which he later confirms is one of the "Big Fifty." Carl also reveals to Webb that the "Indian" was a white man in disguise. Later, Rocca greets Webb and his men at the reservation where the Cheyenne chief is grateful for the delivery of the much needed cattle. The men have left the buffalo gun in a hidden location, and when they return for it, are accidentally sprayed by a skunk, but fortunately run into Eddie G. Hubbard, who is making a delivery of goods to his sister's store. Eddie provides the men with new clothes and several cans of food before departing. Webb and the men are dismayed to find that their matching outfits are those of a singing group, but are even more concerned when they discover gun powder and buffalo gun shells in the cans. Before Webb, Marty and Carl arrive in Las Cruces, Miller intercepts a coded telegraph message to the sheriff revealing Webb's identity as a government agent. When Miller takes the information to Rocca, he orders one of his men to don his Indian disguise and intercept Webb. Rocca's men ambush Webb and his deputies just outside of town, but the agents outsmart their attackers and continue into town. Although Webb wants to question Eddie about the canned supplies, Marty is more interested in meeting Eddie's sister Clementine. Under questioning from Webb and Carl, Eddie reveals that part of his delivery was Murdock's treaty supplies for the Indians and that Murdock was furious that he had sold them to Webb. After Marty arranges a date with Clementine for a dance that evening, he, Carl and Webb go to the sheriff's office. Although suspicious of the men's attire and Webb's inability to provide his identification papers, the sheriff believes the men after they inform him of their mission to locate the "Big Fifty." At the telegraph office, the sheriff asks Miller why he never received the wire informing him of Webb's arrival, but Miller insists he delivered it. As the men depart, Webb realizes Miller is sending a message to a nearby town requesting help to move out the stolen guns. Later, Rocca meets with his cronies to plan moving the guns, which are hidden in Murdock's barn, after the dance, which is being held there. Webb and his men visit Rocca, who admits that Murdock has been selling the excess government supplies to miners in a nearby town. Webb reveals he is an agent and requests Rocca's help in preventing the "Big Fifty" from falling into the hands of Geronimo. Miller overhears the conversation from the store room and, panicking, flees after Webb departs. While Webb, Carl and the sheriff wait for Rocca to lead them to the guns, Marty tracks Miller down and takes him to jail, where Miller admits his involvement with Rocca. That evening as the dance begins, Webb and the men realize that the guns must be in Murdock's barn and attend the dance without revealing Miller's arrest. Eddie goes in search of Marty for standing up Clementine, and upon discovering Miller in jail, is hastily deputized to gain his silence. Later at the dance, however, after Marty cuts in on Murdock's dance with Clementine, Eddie reveals Miller's arrest. Rocca privately orders his men to begin smuggling out the guns while Murdock asks Marty and Webb to sing, hoping to distract them. Meanwhile, other of Rocca's men cause a cattle stampede in order to break up the dance. Carl and Marty race to divert the cattle back to the river, while an associate of Rocca's murders Miller in jail. Webb, Carl and Marty return to the barn in time to catch Rocca and his men attempting to smuggle out the guns. After a fight, Webb subdues Rocca and, with the sheriff's help, arrests Rocca and his men. Eddie stumbles upon the boxes of the "Big Fifty," and the relieved townspeople return to the dance. The next day Webb, Carl and Marty leave Las Cruces, but Marty soon returns for Clementine.
