The film centers on Max Fischer (Jason Schwartzman), a precocious and eccentric 15 year-old, who is both Rushmore's most extracurricular and least scholarly student; Herman Blume (Bill Murray), a disillusioned industrialist who comes to admire Max; and Rosemary Cross (Olivia Williams), a widowed first grade teacher who becomes the object of both Max's and Herman's affection.Max's life revolves around Rushmore Academy, where he is a scholarship student. Max spends nearly all of his time on elaborate extracurricular activities, caring little how it affects his grades. He also feuds with the school's headmaster, Dr. Guggenheim (Brian Cox).Blume finds his operation of a multimillion dollar company to be unsatisfying and is frustrated that his marriage is failing and the two sons he's putting through Rushmore are unrepentant brats. He and Max become close friends; Max admires Herman's success while Herman is impressed by Max's cocksure attitude.Ms. Cross arrives at the academy as a new teacher after the death of her husband (and former Rushmore student), and Max quickly develops an infatuation. He makes many attempts at courting her. While she initially tolerates Max, Ms. Cross becomes increasingly alarmed at his obvious obsession with her. Along the way Blume attempts to convince Max that Ms. Cross is not worth the trouble, only to fall for Rosemary himself. They begin dating without Max's knowledge.After Max attempts to break ground on an aquarium without the school's approval, he is expelled from Rushmore. He is then forced to enroll in his first public school, Grover Cleveland High. Attempts to engage in outside activities at his new school have mixed results. A fellow student, Margaret Yang (Sara Tanaka), tries to engage Max, but he pays little attention to her. Rosemary and Blume attempt to support him in his new school.Eventually, Max's friend Dirk (Mason Gamble) discovers the relationship between Rosemary and Blume and informs Max as payback for a rumor Max started about his mother. Max and Blume go from being friends to mortal enemies, and they engage in back-and-forth acts of revenge on each other. Max informs Blume's wife of her husband's affair, thus ending their marriage. Max then puts bees in Blume's hotel room, and then Blume destroys Max's bicycle with his car. Max also cuts the brake lines on Blume's car, for which he is arrested.
