On September 15, 2008, Lehman Brothers filed for Chapter 11 bankruptcy, the largest such filing in American history, and this film reconstructs the days leading up to it. It traces the firm's buildup of mortgage-backed securities and real estate risk, the drying up of client confidence, and the frantic weekend negotiations at the New York Federal Reserve where executives from rival banks and government officials tried and failed to arrange a rescue or buyer. Interviews and archival news footage lay out how talks with Barclays and Bank of America collapsed, why the government refused a bailout this time after backing Bear Stearns months earlier, and how the bankruptcy filing sent shock waves through global credit markets almost immediately. The film keeps its focus on the mechanics of the collapse itself: the balance sheet decisions, the regulatory hesitation, and the closed-door arguments among bankers and officials that determined which firms would survive 2008 and which would not.
