First day of this past year for the students of a high school mathematics, however in the school there is something new: many guys have been transferred from their respective classes in a section created especially for them, '' the section H. Students of the H section really are not were chosen randomly, are in fact notoriously problematic elements, overly exuberant and listless. Included in this is Ricky (Enrico Oetiker) who's alert and never misses a chance to produce jokes irritating it stocks onto its Youtube station, Star (Greta Menchi) whose only interest is its look and Viola (Alice Pagani) bright but always at war with all the world.
