Its name stirs images of the savage, the untamable. Legend paints it as a solitary, blood-thirsty killer that roams the icy heart of the frozen north, taking down prey as large as moose, crushing bones to powder with its powerful jaws. But there is another image of the wolverine that is just beginning to emerge, one that is far more complex than its reputation suggests. This film takes viewers into the secretive world of the largest and least-known member of the weasel family to reveal who this dynamic little devil truly is. Hard-wired to endure an environment of scarcity, the wolverine is one of the most efficient and resourceful carnivores on Earth.
Part of the massive Tongass National Forest, Admiralty Island in southeast Alaska supports the largest concentration of bears anywhere in the world. Sustained by a wealth of salmon streams, isolated and protected by their environment, some 1,700 Alaskan brown bears are part of a unique circle of life that has played out here for centuries. Beginning in August, millions of salmon — pink and chum, coho and sockeye — return to the island to spawn, providing a feast for the bears, eagles, orcas, sea lions and even the trees. As long as the salmon continue to arrive, all is well. But this year, the salmon fail to arrive for the first time, and the bears get a bitter taste of what the future may hold.
