It is here that bear-hunting wolves take to the sea, grizzlies clash in titanic battles, 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. Forming a wilderness detective squad, these experts are searching for the rare white spirit bear and collecting clues that will decipher the secret life of the forest's elusive inhabitants.
