What begins as an annual Labor Day weekend is anything but normal for a small Minnesota resort town. First, a boy is dragged from his yard by an unknown creature. Afterwards, the carcass of what appears to be a young sasquatch is found in a local lake. Why the abduction? And how did a "Rugaru," as the Ojibwe call the hairy man who appears in evil times as a warning, end up in Blackwater Lake? Prompted by a news alert, Canadian wildlife biologists Thor and Ellie Svendahl leave for the lakes and forests of Minnesota to prove the Indian community correct. With the help of a forensic anthropologist, an autopsy unveils convincible evidence surrounding harmful pesticides plaguing the diversified habitat of the Bigfoot.
