Bored with their usual summer games, Kat and Tanya want to play with the neighborhood boys. The boys a real teepee in their backyard! But they refuse, telling the sisters it's for native American boys only. The girls resort to desperate measures and blackmail the boys into including them. But "Chief" Randy isn't ready to surrender. He creates three initiation tests for the sisters to pass. Can the girls pull a few tricks from their sleeve and become tribe members in this boy versus girl war of the summer?
