Cady (Lindsay Lohan) is the new girl in town. After befriending a couple quirky
kids, they decide Cady should infiltrate the Plastics to take down the mean girls from the inside. But while she's trying to bring down their leader Regina George (Rachel McAdams), she slowly but surely becomes one of them, eventually taking on the crown after she fully shuts Regina out. But Cady realises in the end that a mean girl isn't who she truly is — she's a maths nerd who deeply cares about her friends and wants everyone to get along. Smart girls like Cady and Elle Woods have to stick together!
