Plot
Yasmin, Cloe, Sasha and Jade are four teenage best friends and are about to start their freshman year of high school together in Los Angeles. There, Meredith Baxter Dimly, a rich, popular and extremely controlling student body president, wants everyone to belong to a clique, and goes about organizing students. However, Meredith dislikes the independent spirit of the four girls and immediately realizes they will pose a problem to her plans, plotting to ruin their friendship and make them conform to her prefabricated cliques.
Cloe is a soccer player and meets Cameron, on whom she instantly develops a crush, distancing herself from her friends. Sasha is recruited as a cheerleader and joins the cheerleading squad. Jade joins the science club, then meets Dexter and discovers a passion for fashion design. Yasmin joins the journalism club, but later decides to focus on singing before she meets Dylan, a popular yet laid-back jock, who is deaf but can lip read, who misses being able to listen to music. Though the girls try to make time for each other, they are all busy with their own respective interests and new friends. The friends begin to drift apart as they are compelled to stay within their cliques due to Meredith's plans.
Two years later, an accidental food fight causes them to get detention for breaking Principal Dimly's statue after Meredith sends her pet dog, Paris, to attack Cloe from flirting with Cameron. The girls realize that they miss being close friends and decide to recover that connection. They also try to get the other schoolmates to socialize outside their cliques. However, the girls find out they are not invited to Meredith's second "Super Sweet 16" birthday party, but they are forced to work for Meredith due to Cloe's mom having a job serving food. At the party, Meredith decides to expose Yasmin's secret (video footage of her dancing and singing with a face mask). When Dylan and Yasmin's brother Manny starts doing a conga line and everybody joins in, Meredith is humiliated. The party ends disastrously when Meredith accidentally gets smothered on her cake and thrown into the pool with her friends.
The next day at school, the girls decide to be part of the talent show to win a scholarship. Meredith is always the one who wins, yet the "Bratz" are prepared to take her down. Later, Meredith tries to blackmail the girls by using an embarrassing photo to have them quit the talent show. This results in her plans to backfire with everyone else's secrets being revealed publicly. This idea brings all the cliques together again, and the girls perform an elaborate musical number. Meredith constantly attempts to steal the spotlight. In the end, there is a tie. Meredith gets the trophy, but the girls win the talent show and they decide to give Cloe the scholarship. They are offered an appearance at a red carpet gala by an MTV vice president, while Meredith and her father Principal Dimly attempt to foil the girls' attempts but fail.
