When a Russian criminal is torn to pieces by a powerful animal, Moscow cop Lev Dasaev follows the trail to the U.S. - and to the lair of a murderous madman called Wheeler Burns.
Ruth Templeton will stop at nothing to destroy Laura Greenacre, the mysterious woman who was last seen disappearing into the tunnels beneath London - and her quest leads her to America.
The Templetons and the Greenacres will go to war one last time. And as in London eight years previously, werewolves will be unleashed - this time on the streets of New York.
Bloodlust and vengeance unite Ruth and Burns as they conspire to annihilate Lev and Laura - and the ultimate hunter becomes the ultimate prey..
