A young girl is brutally abducted by a bloodthirsty grizzly, forcing a group of scientists to mop up a genetic engineering operation that is out of control, threatening any and all who enter the woods. One question remains: are the animals really dangerous for no reason at all or does their enhanced intelligence simply make them recognize something damning about human nature that needs to be understood before it's too late?
Two groups of scientific researchers are sent into the forests where animal attacks are frequent to study what is happening only to find themselves attacked and outsmarted (in part) by the animals themselves. Two environmental action groups find themselves at odds over the fate of the dangerous genetically-enhanced creatures. One group wishes to see the offensive beasts destroyed and the other wants to preserve them at all costs, even at the sacrifice of human life. The two sides find themselves at an impasse, unable to resolve their differences in an amiable way, leading to ever-increasing tension, animosity, kidnapping and murder.
Entire forests are quarantined in an attempt to control and contain the beasts but soon holes are discovered in the operation as key players start disappearing in addition to animals eluding their hunters, fighting back and changing the field of battle to their own terms.
As the "pro-beast" and "pro-human" sides pursue to their own interests with the unfortunate bears caught in the middle (struggling to establish themselves in a human dominated world), the animals learn more and more to rely on their expanding awareness to survive and thrive in their new world...to evolution-shattering effect.
