Black dude with dreds goes to Alaska and joins with the natives and is discovered to be the tribes chosen one. They perform a ritual and send him to the great beyond where he kills the demon who's been possessing polar bears and using them to kill people who try and settles the wilds of Alaska.
Here our hero is faced with conflict, should he kill the demon and save the tribe? Or should he join forces with the demon to protect the land from human spoiling? Helping the demon would mean turning his back on the tribe that loves him, but he has also seen how humans have destroyed so much of the wilderness and wildlife that he thinks something has to be done to stop them from destroying everything.
