Because he believes in education, a ranch owner hires a school teacher from the east and opens a school for his cowboys. The teacher is admired by all of the cowboys, and by one in particular, an outlaw, who frightens all the pupils one morning by writing "school" with bullet holes on the blackboard. Broncho Billy steps in and sends him over the county line. Later, three of the pupils find a torn letter which the teacher has lost, and, piecing it together, learn that the girl's mother is worried because lack of money prevents her visiting her daughter. They take up a collection and send for the mother. Broncho Billy, the sheriff, loves the girl and proposes to her. She accepts him and they are married. Just as the minister pronounces the closing words, in walks the bride's mother, making the happiness of the event complete.
