Bored with their usual summer games, Kat and Tanya want to play with the neighborhood boys. They have a real teepee in their backyard! But the boys refuse, saying it's for Native Americans 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?
