Using a female orangutan as a surrogate, the doctor's cloning efforts are successful and seem to be under control until the pregnant orangutan is set free by an animal rights group. The orangutan delivers her cloned infant in the woods and soon dies, leaving the young skunk ape alone to roam the wilds with only his animal instincts to guide him. Three years later he is looking for a mate and savagely rapes a young woman named Emily Wilson. Not long after that he beats a hunter to death. Emily, whose life is forever changed because of the attack, joins forces with Jim Smith and Deputy Billy Eagle to find the beast and stop him before he attacks again. But will their efforts be too little too late?
