Mark Whitacre (Matt Damon), a rising star at agri-industry giant Archer Daniels Midland (ADM), suddenly turns whistleblower. Exposing his company’s multinational price-fixing conspiracy to the FBI, Whitacre imagines himself as a kind of de facto secret agent. Unfortunately for the FBI, their lead witness hasn’t been quite forthcoming about helping himself to the corporate coffers. Whitacre’s ever-changing account frustrates the agents and threatens the case against ADM as it becomes almost impossible to decipher what is real and what is the product of Whitacre’s rambling imagination. Based on the true story of the highest-ranking corporate whistleblower in U.S. history.
