Firefighters, teachers, and police officers across America are counting on pensions that may not be there when they retire. This FRONTLINE investigation follows the growing crisis in public pension systems, traveling to Kentucky, Illinois, and Dallas to show how decades of underfunding, optimistic investment forecasts, and political can-kicking left states and cities owing trillions more than they have set aside. Interviews with retirees, current employees, actuaries, and state officials lay out how governments and Wall Street firms responded by chasing higher returns through hedge funds and private equity, deals that came with steep fees and, in some cases, steeper losses. Dallas's police and fire pension fund stands as a cautionary case, nearly collapsing after a run on withdrawals. The film tracks the political fights over benefit cuts, fund rescues, and who ultimately pays: taxpayers, workers, or both. It closes with the question hanging over every one of these systems: how many more years they can keep the promises already made.
