New student Cady Heron is welcomed to the top of the social chain by the elitist popular girl group called “The Plastics,” ruled by scheming queen bee Regina George and her minions Gretchen and Karen. However, when Cady makes the grave mistake of falling for Regina’s ex-boyfriend, Aaron Samuels, she finds herself in Regina’s sights. With the help of her outcast friends Janis and Damian, Cady sets out to take down the predator in the group and learn to be true to herself in the most ruthless jungle of all: high school.
