Somewhere deep in America’s big backyard, wild things are stalking their prey – little do they know, they are being hunted themselves; acclaimed wildlife tracker Casey Anderson camps out on a wild island to investigate aggressive Wolves, rappels into a cave in search of Vampire Bats, comes face-to-face with a rare herd of Alaska’s gargantuan Moose, slices his way through ‘Gator-Heaven’ in the Florida Everglades, helicopters in to witness a face-off between Bighorn Sheep and Mountain Lions and finally, goes into the heart of darkness to experience the unknown world of Yellowstone’s Grizzlies at night.
