Gun Brothers

On a Wyoming stagecoach bound for Cheyenne, a gang of masked outlaws robs the coach and seizes government gold. Chad Santee, a former Cavalry sergeant, tries to defend the coach but is knocked unconscious as Jubal is revealed among the robbers. Rose Fargo then exposes money hidden in Blackjack Silk's boot, and Chad awakens to see Blackjack slapping Rose before Chad punches him.

A posse arrives led by Yellowstone Kelly, Chad's former army commander. He offers Chad the chance to join him in Jackson Hole for a fur-trading venture, but Chad says he is bound to help his brother Jubal in the cattle business.

In town, Chad begins courting Rose, but Shawnee arrives to take him to Jubal's ranch. Chad leaves town with Shawnee and is joined by Meeteetse, an Indian maiden who accompanies them to show the way.

They reach Jubal's ranch and discover there are no cattle; the place is a hideout and Jubal is the gang's leader. Chad notices Meeteetse wearing a brooch taken from Rose during the stagecoach hold-up and realizes Jubal's gang robbed the coach. Shawnee wants Chad dead for knowing too much, but Jubal vouches for Chad's honesty; Chad reveals his plan to head to Jackson Hole, and Jubal sends Meeteetse along to guide him.

On the road toward Jackson Hole, Chad and Meeteetse stop in town to return the brooch to Rose. Blackjack sees the brooch with Chad and informs the sheriff, who confronts Chad. He flees the confrontation but is shot while escaping, and Meeteetse and Rose rescue him back to Jubal's ranch.

Shawnee's jealousy grows and he wants Rose for himself. Meeteetse goes to town and offers to tell the sheriff where Jubal's ranch is if he arrests Rose and lets Chad go, threatening to betray them if needed.

Chad and Rose plan to leave the ranch in secret, but Shawnee catches them and Chad wounds him. The sheriff and his men arrive and a gun battle erupts between the sheriff's faction and the outlaws.

By the end of the battle, most outlaws are killed or arrested, and Chad, thinking Jubal is dead, rides off with Rose to start a new life in Jackson Hole. Jubal and Shawnee survive, escaping wounded.

Jubal, though wounded, teams with Shawnee to form another gang and heads toward Jackson Hole to kill Chad and seize the furs. They vow revenge and move to surprise the brothers.

Jubal confronts Chad in Jackson Hole, and Chad convinces him that he did not betray him. Shawnee seizes Jubal's gun and vows to assemble the rest of the gang for a final assault.

Shawnee's gang returns to attack Chad and Jubal. The brothers defend themselves and hold off the outlaws, but Jubal is mortally wounded while saving Chad and Rose.

Jubal dies heroically, and Chad and Rose honor him by naming their newborn daughter Jubilee. The furs and Jubal's memory bind the family together.

With Jubal gone, Chad and Rose begin a new life in Jackson Hole, cherishing Jubal's memory as they raise Jubilee. The frontier landscape becomes the backdrop for their fresh start.

Shawnee and the leftover gang vow to return for revenge, suggesting the feud may continue. The threat lingers as the couple builds their life in the wake of violence.

The story closes with Chad and Rose raising Jubilee, a living emblem of Jubal's legacy and a hopeful future. They move forward together, honoring the past while embracing a new family.
