King Corn follows two college friends curious about the food system, as they decide to have a shot at farming an acre of corn. In the process, the two examine the role that the increasing production of corn has had across not only on the concepts of industrial food, but the health of the land, the health of the environment, and the health of people. The film spotlights the role of government subsidies which make huge monocrops of corn possible, which itself has—as industrial agriculture—a catastrophic ecological impact, but in-turn drives factory-farming of animals and other atrocities such as the production of high-fructose corn syrup which is saturated throughout industrial food, not least, fast-food. We see how this industrialisation has eliminated the family farm and local food production—things which are increasingly impossible in this brutal arrangement of corporate power.
