1st day of this past year for the students of some senior high school mathematics, but at school there is something fresh: a few guys have been transferred out of their respective classes in a section created specially to these, the section H. Pupils of the H section are perhaps not were chosen randomly, are in fact notoriously problematic elements, overly exuberant and listless. Included in this is Ricky (Enrico Oetiker) who is alert and never misses an opportunity to create jokes irritating that it shares on its Youtube station, Star (Greta Menchi) whose sole interest is its appearance and Viola (Alice Pagani) intelligent but always at war with the entire universe.
