Having overrun most major cities, the Kannibalen plague now spreads to the forests and waterways of the countryside, devastating climates and casting a cloud of darkness over much of the Earth. In the American Midwest, a pack of infected wolves has reacted strangely to the Kannibalen virus, having been transformed into great were-beasts with cunning intelligence. The leader of the pack, Kai Wachi, must now guide his wolves to safety, for the wilderness is filled with bands of flesh-eating monsters even more dangerous than himself. As he attempts to grasp the realities of his new existence, he fills the night with the chilling sound of his blood-curdling howls.
