St. Kleio Academy is a very exclusive school. To enroll, a student must be the clone of a famous historical figure. Wolfgang Mozart, Queen Elizabeth, Sigmund Freud, Marie Curie, Adolf Hitler--with such a combustible student body, it's only a matter of time before the campus explodes!

Twin boys from Clone Nightingale's distant past are planning to attack the academy, bent on avenging their mother's death. But their plot goes awry, and the brothers are separated. The younger twin attempts to abduct Nightingale, who is now at large. The incident sparks a chain of events that sends all of the clones toward disaster!
