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.

Brothers-in-law, Eduardo and Sabonis, married to sisters Cuca and Peque Ribeiro, have made a real mess of one of their business ventures and are in need of money, a lot of money. It will be Sabonis who, in one of his uncontrollable fits of rage, comes up with a plan to fix all their problems in one go: kidnap Modesto, brother-in-law to Alicia Zamora, the businesswoman who screwed them over. There’s just one problem: Alicia has no intention of paying even a penny to get her brother-in-law back. In the end, it will be Modesto himself who comes up with a new plan to help Eduardo and Sabonis get the money they need to save the family wine business. What they don’t know is that police officer Mati, the Ribeiro’s middle sister, is on to their little plan. Eduardo, Sabonis and Modesto have everything to lose, but as Sabonis would say, what could go wrong?
