#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.

#2 - Inside Death Row
Season 2009 - Episode 10

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.
