Raised in the African bush country by her zoologist parents, Cady (Lindsay Lohan) 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 among jocks, athletes and other subcultures, Cady crosses paths with
the meanest species of all - the Queen Bee, aka the cool and calculating Regina (Rachel
McAdams), leader of the school's most fashionable clique, The Plastics. When Cady falls fro
Regina's ex-boyfriend, though, the Queen Bee is stung - and she schemes to ruin 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.
