The film centres on Moncho and his coming-of-age experience in Galicia in 1936. Moncho develops a close relationship with his teacher Don Gregorio who introduces the boy to different things in the world. While the story centres on Moncho's ordinary coming-of-age experiences, tensions related to the looming Spanish Civil War periodically interrupt Moncho's personal growth and daily life.
