Riley is deep in the wilds of Alaska on a dangerous fix that could impact the pocketbooks of millions. He and a crew of 100 highly trained men and women shut down the Trans-Alaska oil pipeline the only conduit to market for almost 15 percent of the US domestic oil production. This major fix calls for swapping out a 32-ton valve system, but the size of the job is the least of their problems. Crude oil is not just highly toxic; its explosive. Just the batteries on Rileys cameras are enough to spark a disaster. Riley follows the crew as it races to complete the fix in 36 hours if anything goes wrong and the fix runs over, millions of Americans will pay the price.
