A little boy lives with his parents in the countryside and spends his days exploring what nature has to offer: fish, trees, birds, and clouds. One day his father leaves home in search of work in the city. The boy keeps within his heart a melody his father would sing. He goes off to look for his father and discovers a completely alien world of extensive cotton fields, cavernous factories, towering gates, and overcrowded cities. He faces sudden perils along the road to adulthood yet something of the child that gazed at clouds will remain.
