Because of fear and misunderstanding, humans have repeatedly tried to obliterate wolves. These amazing animals had disappeared from Canada's world-famous Banff National Park. Now, thanks to biologist Paul Paquet, wolf packs range freely once again all the way from Banff through to the mountains of Montana.

Using intensive first-hand observation and sophisticated satellite tracking techniques, Paquet has spent over 10 years studying the wolves of the southern Alberta Rockies and fighting to establish protected migration corridors for the animals he has championed so passionately.
