Two groups of students - the third-class high school students and the matured accountants - decide to perform a show to celebrate the last day of school. The comparison on the theater seems to be a further challenge between the two groups after the ball games. Led by the "nerd" eyewear Carletto, who wants to be a director when he grows up, the high school students prepare numbers of rank, from the opera house; the accountants, orchestrated by Fulvio, try their hand at songs and variety. A total failure equally gratifies both.
