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.

Bloodlust and vengeance unite Ruth and Burns as they conspire to annihilate Lev and Laura - and the ultimate hunter becomes the ultimate prey..
