During his vacations, 12-year-old Manuel travels by train with his mother to the Sierra Tarahumara to spend a few days with his father, who works in the mountains with the indigenous people protecting nature. Manuel befriends Jesus, who takes him to his town and teaches him the customs of his own. Both children discover illegal loggers.
