The 2008 financial crash unfolds across four episodes built from interviews with the people who lived it: Treasury Secretary Hank Paulson, Federal Reserve chair Ben Bernanke, New York Fed president Timothy Geithner, and bankers including JPMorgan's Jamie Dimon. FRONTLINE traces how mortgage-backed securities and credit default swaps turned a housing downturn into a near-collapse of the global banking system, walking through the decision to let Lehman Brothers fail, the emergency bailout of AIG, and the scramble inside the Fed and Treasury to stop a run on money-market funds. Later episodes follow the aftermath into the European sovereign debt crisis in Greece and Italy, the political fight over financial reform in Washington, and the anger that boiled over into Occupy Wall Street. Archival news footage and boardroom-level interviews reconstruct decisions made in a matter of hours that reshaped economies for years. The series stays close to the officials and bankers who made the calls, letting their own accounts carry the weight of what went wrong and what, if anything, changed afterward.
