Seen through the eyes of small, midsize and large Mexican maize producers, Sunu weaves together different stories from a threatened rural world. It journeys into the heart of a country where people encourage their determination to stay free, to work the land and cultivate its seeds, to be true to their cultures and spiritual ways, all in a modern world that at the same time both needs them and disdains them. Sunu reveals how maize and everything it gives life to could be lost forever, and shares a generous tapestry of simple, heartfelt messages to the farmers of the world and the city dwellers who could lose the ability to make the choice unless they act soon.
