Summary of the entire program below.

It is September 2009. A Category 5 hurricane roars through Houston, destroying oil refineries, drilling platforms and pipelines--the complex system that provides a quarter of our nation's daily fuel supply. Three days later, terrorists attack two key oil installations in Saudi Arabia, the world's largest supplier. In the days and weeks that follow, gasoline prices hit record highs, food prices soar as trucks cannot afford to make deliveries, and Americans begin to realize that their very way of life is in peril.

In We Were Warned: Tomorrow's Oil Crisis, CNN's Frank Sesno explores the potential ripple effects of this frightening scenario. The events depicted are hypothetical, but oil experts believe the scenario is entirely plausible. His interviews with energy experts reveal that we are nearing the point at which the world, led by the U.S. and China, will begin to consume more oil than can be pumped from the ground and the oceans. Tracking the global race to find new pools of oil, Sesno also considers the viability of alternative fuels, such as ethanol, which is used as fuel for 40% of cars in Brazil. Throughout his investigation, Sesno tries to find out whether any of these ventures can solve our looming energy crisis or whether we are already too late.
