Johanna "Jo" Mitchell is a 17-year-old tomboy who lives with her father, a builder of race car engines for NASCAR. On her first day at North Shore High School, she encounters the school's most popular and snobbish clique "The Plastics" which consists of Amanda "Mandi" Weatherly, a girly girl from a wealthy family, Chastity Meyer, a seemingly slow-witted blond with a raging libido who is known for casual relationships with guys, and Hope Plotkin, a germophobe.

Jo also meets Abigail "Abby" Hanover, a tortured artist who lives across the street from Mandi. Mandi sees Abby as a rival, due to the greater wealth of Abby's family. Jo also develops an attraction to Tyler Adams, a boy in her woodshop class, despite his somewhat sexist attitudes which spur her to excel in the class. Despite Jo's attempts to avoid the Plastics, conflict develops between them and Abby, which includes personal confrontations and vandalism to Abby's car.

When Jo meets Abby's father Sidney, a successful infomercial entrepreneur, he offers to pay Jo's college tuition in gratitude for becoming a friend to Abby. After Jo accepts, she and Abby become closer. She also becomes closer to Tyler, but while on a date with him, a voice recorder placed in the car records her while she divulges some intimate personal details (such as the fact that she is a virgin) and the recording is later publicized. Despite Jo's anger when she discovers this, a group of less popular girls tell Jo that they wish they had waited for sex as she had, making Jo feel better. Jo also learns from Abby that Tyler is Mandi's stepbrother. Mandi also escalates her war of pranks by ruining Jo's class project, thus ruining her acceptance into Carnegie Mellon University, and filling Jo's father's race car with coffee and sweetener.

To get revenge on Mandi, Jo plans a party at Abby's house on the same night of Mandi's birthday party, which harms the level of attendance at the latter. The Plastics retaliate by placing ipecac on the pizza delivered to Abby's house, planning to make all the guests vomit after they consume a slice. Jo discovers that Hope had paid the delivery man to add the syrup, and decided to dispose of the tainted pizza. She and Abbey decide to serve a piece to Mandi's boyfriend Nick, who throws up on her pink dress while making out with her.

A week later, Jo, Abby and another outcast girl named Quinn start a new clique called the "Anti-Plastics" in order wage wars against the Plastics, but as they enact a series of pranks against Chastity and Hope, Jo develops a personality almost as shallow as Mandi, and their campaign threatens Tyler and Jo's relationship. When Jo tries to give back the money Sidney Hanover gave her for her friendship with Abby, Mandi overhears the encounter, and reveals their transaction to the entire school, which leads to Jo's estrangement from both Abby and Tyler. Quinn is also revealed to be a double agent for the Plastics who supports Mandi. Mandi, along with Nick, frame Jo for theft by placing stolen charity money in Jo's backyard shed, resulting in Jo's expulsion.

Tyler and the other Anti-Plastics try to help Jo prove her innocence with the help of Elliott, a computer hacker who infiltrates the computer of Jo's grouchy neighbor, who installed cameras to monitor what happens across the street. After beating the Plastics in a game of powderpuff football, Mandi and Nick are arrested after images of them planting the money in Jo's shed are revealed (the images are found by Elliott, who hacks into Jo's paranoid neighbor's video cameras). At the school's homecoming dance, Abby and Elliott are elected as king and queen, due to Jo rigging the voting.

The film's epilogue indicates that Mandi and Nick were sentenced to community service, and that Mandi was allowed to graduate only because her mother donated a library to the school and because of her criminal record her chances of getting into a decent college were destroyed and her parents cut her off from her trust fund. Quinn became the new leader of the Plastics and agreed to end their war with the Anti-Plastics who disbanded. Hope finally overcame her fear of germs and drank from a public water fountain as a boy sneezes on her giving her the swine flu (though she vows to fight it with antibiotics and hot doctors). Chastity ended up joining an abstinence club after learning the meaning of her name. Abby and Elliot begin a relationship as she goes off to college to major in art, while Jo, who remains close friends with Abby, rekindles her relationship with Tyler, who attends Penn State University to remain near her.
