Biography
Loretta Creswood is the principal of Hubert Humphery High School in a sleepy suburb of Phoenix, Arizona. She was a woman who did not care who she walked over to make the school a better place. Loretta would start files on students with low S.A.T. scores and those she felt were undesirable were hounded out of the school, some of those students were Luis Chavez, Mazz Mazelli, and a few others.

Things start to get crazy when a pirate radio show created by a student named Mark Hunter a.k.a. "Hard Harry" or "Happy Harry Hard-on". No one knows his true identity.

Eventually, the radio show causes so much trouble in the community that the FCC is called in to investigate. During the fracas, it is revealed by Jan Emerson, one of Mark Hunter's teachers that Loretta Creswood, the school's principal, has been expelling "problem students," namely, students with below-average standardized test scores, in an effort to boost the district's test scores while still keeping their names on the rolls (a criminal offense) in order to retain government funding.
