In a time of global warming and spiralling damage to the environment, the Virgin Zones were established to help combat the change. Abandoned by humanity and given back to nature, these vast areas in a dozen remote locations across the planet were intended to become the lungs of the world. But there are always those drawn to such places. Extreme sports enthusiasts and adventure racing teams target the dangerous, sometimes deadly zones for illicit races. Only the hardiest and most experienced dare undertake these expeditions. When one such team enters the oldest Zone, Eden, they aren't prepared for what confronts them. Nature has returned to Eden in an elemental, primeval way. And here, nature is no longer humanity's friend.
