Cady Heron (Lindsay Lohan) is an innocent teen who has been home-schooled by her parents most of her life, but now she has to face the real thing. She initially makes friends with a couple of the class outsiders, but when the “Plastics” (a clique of the richest, most beautiful, and most obnoxious girls in the school) invite her to join them, her friends encourage her to accept the opening. Their plan is for Cady to infiltrate the clique and bring back juicy insider information. But as Cady spends more time with the Plastics, she becomes more and more like them, until her friends start wondering if she has turned to the Dark Side. Subtle in places, spikily barbed in others, it’s a lot funnier and more interesting than your standard teen comedy.
