The movie begins on May 14, also known as ''Rock 'n' Roll High School'' day at Ronald Reagan High. The students decide to play a prank on the faculty of the staff, flushing all of the toilets in unison and causing the faulty pipes to burst (yet again), causing for widespread mayhem in the school, as other students leave their classrooms and run rampant down the hall with the perpetrators who organized the entire thing: four members of the band known as The Eradicators. During the confusion, their friend (and the fifth band member) rides through the halls on a dirt bike as well.
