Deep in Canada's rugged western coastal mountains a new hydroelectric project is underway. It's a 600 million dollar venture diverting massive glacial rivers into a huge pipeline built against down steep mountain slopes. In the valley below turbines will be installed to generate electricity sent out to the coast by a new transmission line carved through heavy bush. A tight group of rugged bushwackers and fearless engineers are building all of it in spectacular but remote bush where grizzlies roam and eagles soar. There's no road access so the crews fly in by seaplane to work for weeks at a time. It's a dangerous job where crews work in all kinds of weather from heavy snow with a threat of avalanches to extreme heat with a threat of forest fires. Accidents including a deadly plane crash shake the workers but don't stop them.
