On his first trip to the city, Panchito, a peasant boy, is lost in a fair in El Alto (Bolivia). Despite his efforts and those of the father, he ends up in an orphanage. During school civic hour, in which the more than a hundred years in which Bolivia lost the exit to the sea against Chile are remembered, he meets Pedro, a Chilean boy who lost his parents in Antofagasta (Chile). Panchito wants to return to his home in the countryside next to the father. Peter has the illusion that the sea is the immense blue door to the sky that will take him to his parents. This feeling unites them on a journey between the arid high plateau, with the whistle of the earthy wind, and the vigorous wind over the waves of the ocean. But fate is not always expected.
