Philippe Cousteau explores the wild frontier of Alaska.  He takes a trip deep into bear country and witnesses a brown bear hunting for salmon.  We fly through the Denali National Park and land on a glacier near the tallest mountain in North America.  Philippe goes scuba diving in the frigid waters near the Kenai Peninsula and discovers an abundance of sea life.  Then Philippe tries his hand at panning for gold, which is still plentiful throughout Alaska.
