By day, Mark Hunter (Christian Slater) is a painfully shy new kid in a small Arizona town. But by night, he’s Hard Harry, the cynical, uncensored DJ of a pirate radio station. Idolized by his high school classmates (who are unaware of his real identity), Harry becomes a hero with his fiercely funny monologues on sex, love, and rock and roll. But when he exposes the corrupt school principal, she calls in the FCC to shut Harry down.
