The Pretender(1918)

After Bob Baldwin is fired for playing too many jokes on the tenderfoot owner of the Diamond K Ranch, he sets out for the nearby town of Freloe Beanos and meets Percival Longstreet on the way. Percival has been seriously injured in an accident and is therefore unable to assume his duties as the town's new schoolmaster. Distressed, Percival confesses that he and his sister Dolly, who is en route to the town, are doomed to starve, which so moves Bob that he agrees to serve as the schoolmaster during Percival's convalescence.
