It's a classic story: Legions of families leave their native land in search of better lives and jobs. They settle in California's Central Valley to work on the farms. It's hard labor, pay is poor and the community often is hostile to these outsiders who struggle to keep their families unified and healthy.

There are moments of catastrophe and tragedy, but it's mostly a narrative of human perseverance.
