The pack ice off the coast is melting and depriving polar bears of their habitat so that they approach human settlements in their desperation. The changes in the nature of the Arctic Circle combine with the measurements of researchers and observations of the indigenous people to form a disturbing overall picture: In the Russian Arctic, Pandora's box has been opened!

Venture into the trackless Arctic wastes to witness the uncanny survival strategies developed by this magnificent creature – tactics honed to a killing edge during 250,000 years of adaptation to its icy kingdom. See why the largest of these fearsome bears, weighing more than two full-grown lions, stands as the undisputed predatory monarch of a pristine, unconquered land where man still ventures at his peril.

The wolves' legendary intelligence, their lethally effective social hunting skills and awesome powers of endurance are all put to the ultimate test in a life and death struggle against man's most modern weapons... and most primitive fears.

A sudden explosion of lunging, scaled fury, a hopeless, panicked struggle... a silent, watery death. Crocodiles and alligators reign as the supreme predators in rivers and coastal areas around the globe.
