A rising star at agri-industry giant Archer Daniels Midland, Mark Whitacre (Matt Damon) suddenly turns whistleblower. Even as he exposes his company's multinational price-fixing conspiracy to the FBI, Whitacre envisions himself being hailed as a hero of the common man and handed a promotion. Unfortunately for the FBI, their lead witness has been less than honest about helping himself to the corporate coffers and it becomes almost impossible to decipher what is real and what is the product of Whitacre's active imagination.
