Dave Salmoni meets the true survivors of the natural world, when he journeys to some of the globes most remote islands. These islands have developed unique ecosystems and species and these animals have adapted perfectly for their environment.

The cameras are turned on a must-see natural spectacle that plays out across the vast Alaskan wilderness, where some of the world’s most remarkable animals – bears, wolves, moose, orcas and eagles – gather by the thousands to take part in Alaska’s summer feast, an event never before captured live on television.
