The authorities at an adult education center (called CACHADA) are about to receive an inspection that worries them. On the same plane as the inspector is a student with a similar last name, whom they mistake for the inspector. Meanwhile, the students are rehearsing musical numbers at night, having promised to perform at a club. This is discovered by the teachers and the inspector, who decide to punish their students. Furthermore, the school's benefactor, Amalita Fortaviene (a parody of the millionaire philanthropist Amalia Lacroze de Fortabat), arrives, bringing with her the Loma Blanca soccer team (a parody of Club Loma Negra, represented by their River Plate jerseys) to compete against CACHADA (who wear Boca Juniors jerseys). Winning this match is crucial for resolving all the entanglements presented in the film.
