An investigation into the gruesome death of a campground attendant in northern Minnesota takes a bizarre turn when two witnesses insist that the perpetrator was the mythical Bigfoot. The authorities, unwilling to subscribe to the existence of such creatures, come up with an explanation of their own-a bear attack. But without a body, it is left to Charlie Johnson, a local woodsman and tracker, to sort it all out. In doing so, he discovers a mysterious connection to the prehistoric past and a vast underworld far more dangerous than any wild animal. "You think it was a bear then that dragged Monsen away?" Charlie asked. "What else?" "There's a problem with the bear theory." "What's that?" "No other campers heard or saw anything. Seems like a man getting mauled by a bear would have plenty to say about it." "Scream his bloody head off, I'd say." "Yet the body was never found. Kind of hard for even a bear to eat an entire man in one evening, bones and all, don't you think?" "True. What's your take?" "Confused at the moment," Charlie admitted.
