In an eat-or-be-eaten environment, see how the smallest mouse to the largest bobcat lives in a world where every day is unpredictable. Our cameras are front and center. We'll capture the famed upstream swim of the Alaskan salmon in brilliant detail. Then get inside the world of the creatures that call the redwood forest home. And, see how snakes, owls, bobcats and mice all battle for food, shelter and survival among the tallest trees on Earth. Who will take their post as "king" of their land?
