Allie Finkle likes to live by her own rules, such as 'Just because something is popular doesn't mean it's good'. But it's hard to stick to the rules when other people won't play fair. Allie is totally excited when a new girl joins her class! But Cheyenne quickly becomes a complete GIANT PAIN - she thinks she's sooo mature, wearing high-heeled boots and making everyone play the kissing game (yuck!). But when Allie doesn't want to play, Cheyenne gets mad. REALLY MAD. As Allie and Cheyenne go head-to-head, the rules of friendship are about to be broken . . .
