Throughout most of the twentieth century, thousands of Mexicans travelled north to work the sugar beet fields of the Minnesota-North Dakota Red River Valley. North for the Harvest examines the evolution of the relationships between American Crystal Sugar Company, the sugar beet growers, and the migrant workers.

Ultimately, the lot of workers improved as the years went by. As one worker explained, something historic occurred for his family while working in the Red River Valley: "We broke the chain there".
