The easy oil is gone. The age of the tar sands has begun. Yet as a pristine wilderness and a Native people are being wiped out to feed the world's hunger for energy, what no one expected was for them to fight back. This shocking documentary is a journey through the David and Goliath struggle playing out within the major environmental issue of our age.

Stretching out across hundreds of miles the Canadian tar sands are a barren wasteland, broken by smoking towers, silos and the massive tailings ponds filled with toxic waste. "For every barrel of bitumen you create a barrel and a half of waste that goes into those tailings ponds. The majority of them are leaking." Captured in spectacular HD cinematography, these unique pictures reveal an otherworldly apocalyptic landscape and tell the tar sands definitive story.
