Along the coast of British Columbia lies an enchanted wilderness, where bear-hunting wolves take to the sea, grizzlies clash in titanic battle, and wild salmon are the pulsing lifeblood of an entire ecosystem. As this precious habitat faces an uncertain future, threatened by chainsaws, and fish farms, a team of dedicated scientists is racing to prove that it must be protected. National Geographic joins these experts on a 250- mile adventure through unspoiled territory that conservationsists call the Great Bear Rain Forrest. Together, these experts form a wilderness detective squad, searching for the rare white "spirit bear" and collecting clues that will help decipher the secret life of the forest's elusive inhabitants.
