The students of the República de Chile school are going to the country. Professor Esther has just arrived at school and wants her students to get away from the comfort of the city, listen to the call of nature, fill their lungs with fresh air, get to know the flora and fauna of the forest and learn a little about the art of camping. However, Martín Piquín can only hear the call of María Morita, with whom he is madly in love. This second book in the Martín Piquín series provides a humorous glimpse into young love through familiar characters and familiar situations.
