 Raised in the African bush country by her zoologist parents, Cady Heron thinks she knows all about the "survival of the fittest". But the law of the jungle takes on a whole new meaning when the home-schooled 15-year old enters public high school for the first time. Trying to find her place between jocks, mathletes, and other subcultures, Cady crosses paths with the meanest species of all - the Queen Bee, aka the cool and calculating Regina George, leader of the school s most fashionable clique, the Plastics. When Cady falls for Regina s ex-boyfriend Aaron Samuels, though, the Queen Bee is stung - and she schemes to destroy Cady s social future. Cady s own claws soon come out as she leaps into a hilarious "Girl World" war that has the whole school running for cover.
