Alvin Johnson (Nick Cannon) is an extremely intelligent nerd under consideration for a General Motors scholarship, as he is skilled in designing engines. He has also taken up a job as a pool cleaner, to raise money to buy an expensive car part. He's always dreamed of hanging out with the popular kids, especially Paris Morgan (Christina Milian), a beautiful, popular cheerleader dating NBA star Dru Hilton. When Paris crashes her mother's expensive SUV during an argument with Dru, Alvin agrees to repair the car in return for two weeks of dating. Alvin uses money he had saved all summer for his project, jeopardizing his scholarship.
