A young eastern girl arrives at the ranch and sets the boys agog with her beauty. In order to gain her favor. Slim attempts to make himself out a hero, which he does by bullying an inoffensive Indian. Molly, jealous, discovers Slim's attempt to appear brave and later overhears the plans by which he hopes to win the fair easterner. Slim invites the city girl to go for a buggy ride and arranges with the cowboys to disguise themselves as Indians and attack them, so that he may glorify himself by saving the fair damsel. The boys disguise themselves and are about to fulfill Slim's plans when Molly, by a clever ruse, compels them to remove the paint and feathers and remain at home. Angry at the insult previously offered to him, Big Brave hurries to his people and incites them to war. They capture Slim and his lady fair and take them to their village. In the meantime, a trapper spreads the alarm and Molly and the cowboys, now scared, start out to the rescue. The cowboys rout the Indians. At Molly's instigation, the boys again don their Indian war paint and give Slim the alternative of marrying a squaw or being burnt at the stake. Slim decides to burn. Just at the moment when things are becoming serious for Slim, he learns of the joke. Big Bill has, in the meantime, "copped" the city girl, and Slim goes back to his first love. But she also spurns him.
