In the remote forests of Maine, Dr. Robert Verne and his wife, Maggie, are sent on an environmental study to resolve tensions between a logging company and the local Native American community. The Native Americans claim that the company's practices are polluting their land and creating ominous changes in the environment. As Robert and Maggie delve into their investigation, they uncover evidence of severe mercury contamination that has led to disturbing mutations in local wildlife. Among these mutated creatures, they find evidence pointing to the existence of a monstrous, bear-like creature that has begun to terrorize the forest.

As tensions rise between the logging company and the Native Americans, Robert and Maggie must navigate threats from both man and beast. They ally with a Native American activist named John Hawks to search for the creature and expose the truth about the environmental disaster. Their journey leads them deeper into the wilderness, where they face increasing danger and uncover shocking revelations about the consequences of unchecked industrial pollution. The trip becomes a struggle for survival as they attempt to prevent further horrors and bring awareness to the damage being inflicted on the natural world.
