Their recessions are only put to an end by the arrival of a new and young teacher, Kamila, who is not affected by their tried and tested tricks. Despite their seemingly carefree life, each of the boys has his own problems, which gradually surface, and so in the avalanche of funny moments, a serious tone is occasionally heard.
