First day of last year for the students of a high school science, but at school there is something new: some guys have been moved from their respective classes in a section created especially for them, the section H. Students of the H section are not were chosen at random, are in fact notoriously problematic elements, too exuberant and listless. Among them is Ricky who is awake and never misses a chance to make jokes irritating that it shares on its Youtube channel, Star whose only interest is its look and Viola intelligent but always at war with the world.
