He soon discovers the female geologist he's just saved is a Sasquatch who has been marooned on earth and is being hunted by relentless pursuers from here and beyond. As they struggle to survive, Paul finds that his knowledge from his work at "Area 51" may hold the answer to the rescue of the Sasquatch.
