A woman recording instructions about pronunciation lessons for a language class. The diverse students listen to the instruction phrases and repeat them. Landscapes and poor, isolated villages without means of communication. A plane’s propeller. The pilot radios in as he lands. Packages are delivered to Ethiopian villages. An Indian woman sits with a group around her. She is a nurse, and tries to teach the other women how to treat blindness in infants. A baby cries as she treats it.
