A series of films from all over the world about our astonishing planet and the creatures that live on it.

The Grizzly Bear has roamed North America for a million years.
The invention of the repeating rifle brought the feared and hated bear to the point of extinction, but today's inventions are to the Grizzly's advantage.
Scientific devices are enabling John and Frank Craighead to discover the secrets of the great bear so that it may be preserved.
