Mark is an intelligent but shy teenager who has just moved to Arizona from
the East Coast. His parents give him a short-wave radio so he can talk to his
pals, but instead he sets up shop as pirate deejay Hard Harry, who becomes
a hero to his peers while inspiring the wrath of the local high school
principal. When one of Harry's listeners commits suicide and Harry- inspired
chaos breaks out at the school, the authorities are called in to put a stop to
Harry's broadcasts.
