French investigative journalist Marie-Monique Robin spends three years tracing Monsanto's history from a chemical company that made PCBs and Agent Orange to the world's dominant seller of genetically modified seed. She interviews farmers in Indiana, Paraguay, and India who describe being sued or driven into debt after Monsanto's patented soy and cotton entered their fields, and she follows the case of Canadian farmer Percy Schmeiser, taken to court for growing canola contaminated by GM pollen he never planted. Former FDA officials describe how the agency approved Monsanto's bovine growth hormone rBGH over the objections of its own scientists, and internal documents surface showing decades of efforts to bury evidence that PCBs and other company products caused harm. Robin builds the film case by case, letting scientists, regulators, lawyers, and farmers lay out a pattern of lobbying, litigation, and revolving-door appointments between the company and the government agencies meant to police it. The picture that emerges is of a corporation that treats regulatory failure as a business strategy.
