Broncho is instrumental in saving Yellow Wolf, an Indian, from the wrath of Dan Runnion, a surly cowpuncher, and Runnion swears revenge. His chance comes when he sees a notice from the county sheriff advising that cattle rustlers are at work and for ranchmen to watch their stock. Finding one of Broncho's shirts out on the clothesline, Runnion places an incriminating note in the pocket and steals away. Getting the ranchman, he returns to Broncho's snack and accuses him of being one of the rustlers. The ranchman finds the note in the pocket of Broncho's shirt advising Broncho to come and get his share at the proceeds from the stolen cattle, In a rage he summons his cowboys and Broncho is led away to be hanged. Meanwhile, Yellow Wolf, who has witnessed Runnion writing the incriminating note and heard his threat to get even with Broncho, rides madly to town, summons the sheriff, and they arrive in time to prevent the hanging of Broncho. Yellow Wolf tells the story and the guilty Runnion tries to escape, but is captured and meets his just deserts, while the boys gladly congratulate Broncho on his narrow escape.
