The film delves into the life of Antoni Benaiges. He was a teacher from Mont-Roig del Camp in Baix Camp. In 1935m he was assigned to the public school in Bañuelos de Bureba, a small town in Burgos. Thanks to a pioneering and revolutionary teaching methodology for the time, he begins to transform the lives of his students. He also changes the people of the town. Something that is not always to everyone's liking.
