In 1990 a message appears in the press that the Moscow's underground basements are conquered by enormous fierce rats.¿ Fourty years later a high-tech's man wages war on these primitive hairy monsters, which become the new dominating species in the Earth! And they call this absurd slaughter a war! This war has other one, a new, unknown face, an interspecies war. A war, already not only between human beings. A war of the worlds. It is the last war on the Earth!These gigantic rats are a product of mutations. The ordinary grey rats from the urban undergrounds and sewerages have been exposed imperceptibly on the combined influence of the super increased radiation from the numerous consecutive nuclear power station accidents, the powerful electromagnetic fields above the cities and the use of all sorts of toxic chemical substances and preparations. As a result of these mutations the ordinary rats' bodies have changed and rats look like sheep in size nearly 50 inches height while half-upright, with a huge and hairy torso from robust, well-developed muscles, building stocky mass with weight 100-120 pounds. They have improbable physical strength. But the most improbable is their intellect! The TV broadcasting of the wars is in fashion. However, two cold, unmeaning eyes are gazing at the TV monitor too, but with no trace of emotion. A deus ex machina story!
