A Bolivian man pushes behind a plow being pulled by two large cows in an empty field in the Altiplano. Shots of the Bolivian landscape, llamas. Cut to a tall, lean radio tower at a school. A man makes a radio broadcast over the radio in Spanish. Teachers use the radio lessons to teach their young students from all over, in the middle of nowhere. Students all over the world are seen in class, working and learning to secure a better future. One boy reads a braille book at a desk while another types out braille sheets.
