Alaska's Last Oil

#1 - Alaska's Last Oil

Season 2008 - Episode 3

The world is addicted to oil. But now the easy pockets of oil are gone and the race is on to find new sources. Nowhere is the battle more intense than in Alaska - source of nearly 15% of America's domestic production, and home to the nation's largest wildlife preserve, the Arctic National Wildlife Refuge, where companies are pushing to drill. EXPLORER travels back millions of years to see how oil was created, and looks to the future to ask how far we'll go to find every last barrel and at what cost.

Inside Death Row

#2 - Inside Death Row

Season 2009 - Episode 10

In most places death has no schedule, but in Huntsville, Texas, an average of 16 people per year are scheduled to be executed by lethal injection. Inside Death Row interviews three inmates as their dates of execution draw near, and follows the stories of their families and loved ones as they deal with death firsthand. This story is not one of guilt or innocence; it is about how the State of Texas carries out the death penalty as well as the men and women whom, by choice or circumstance, become players in the act of executing another human being. Lastly, it explores how the residents of Huntsville feel towards living in a town that is ground zero for capital punishment in the United States.
