Journalist Eric Schlosser and author Michael Pollan lead a tour through the industrialized food system that puts most American meals on the table, from corn subsidies that ripple through nearly every processed product to chicken houses so tightly enclosed that farmers are barred from showing them on camera. The film follows a Kentucky Fried Chicken supplier, a soybean farmer sued by Monsanto for seed-saving, and Barbara Kowalcyk, whose two-year-old son died after eating E. coli-contaminated beef, as she pushes Congress for a food-safety law bearing his name. Meatpacking plants owned by Tyson and Smithfield appear through hidden cameras and worker interviews describing injury rates and immigration raids. The film also tracks a family choosing between a fast-food dollar menu and fresh produce on a tight budget, making the economics of cheap calories concrete. Kenner builds the case that a handful of corporations now control the food supply from seed to supermarket shelf, largely out of view of the people eating the results.
