Ivan Marx, a wildlife expert, is often called upon to help resolve difficult situations involving wild animals and human beings. When he was called to help with some bears, he made the discovery of a lifetime. The bears were not the problem. Something strange and elusive had encroached into human territory. This discovery took him on a trek across the North American West Coast, through the wilds of Canada, and right to the very edge of civilization. This well documented journey highlights the trials and tribulations of his intrepid pursuit as he chases one clue after another. Ample footage of North American wildlife includes some of the most famous footage ever taken of what many people have called, Bigfoot.
