Expansion into the dense forests of a northwestern America town has intruded on something that has remained hidden for thousands of years. It is attacking campers and stealing babies from homes. While most dismiss the sightings, some believe it is the elusive Sasquatch. A makeshift team is constructed of an anthropologist, a crypto-zoologist, and a construction worker to investigate. They hope to finally discover the Bigfoot before others can exploit it or exterminate it. During the expedition into the forest, one of the team members is abducted by the Bigfoot. While others have died in recent attacks, the creature keeps the team member alive. The reasons, and the creature's connection with man, is more than they could ever imagine.
