Carnos, a greaser, is sent to jail. He is a very refractory prisoner and swears to get even with the sheriff when he is liberated. On the day of the greaser's release, the sheriff had captured Broncho Billy, an outlaw, and was bringing him to justice, when he is suddenly pushed from his horse by the outlaw, and is left to wend his way across the plains afoot. Broncho Billy escapes on the sheriff's horse and unknowingly stops at the sheriff's home for food. Looking through a window he sees the greaser about to take the life of the sheriff's wife. Rushing in, he overpowers the greaser. The posse arrive and take the greaser away. The sheriff thanks Broncho Billy from the bottom of his heart and secures his pardon from the Governor.
