After 12-year-old Evan’s parents get divorced, he moves with his mother from New York City to Appleton, Indiana. Evan has been working hard preparing for his Bar Mitzvah, but all of his friends are back in New York. He is a total outsider in Appleton and desperately wants to befriend the popular kids and have them attend his Bar Mitzvah. He quickly befriends his neighbor, Patrice. Unfortunately, the popular kids do not like Patrice and refuse to attend Evan’s Bar Mitzvah if Patrice is invited. He then rips up her invitation. Not surprisingly, this hurts her feelings. Meanwhile, Evan tries to befriend the school football star, Brett. He tries to help Brett seduce the pretty cheerleader, Kendra. Unfortunately, Kendra’s manipulative friend, Lucy, gets very jealous of Brett’s affections. After various chaotic events, Evan realizes that he didn't really want to be friends with Brett, anyway, and that his only real friends are Patrice and a crippled boy named Archie. He then has a great Bar Mitzvah, albeit with a smaller audience than he had initially planned for.
