Summer is coming to an end in Polar Bear Town, and belugas whales are on the move. Now, only the locals and polar bears remain, and there's plenty to do before the onset of fall. Dennis and Andrew are on a treacherous journey to find an uninhabited island where bears and belugas are rumored to be found in abundance. Kelsey and Karine fly to a remote camp on the hunt for bears that have little human contact. Travelling to a remote lodge on the fringes of Hudson Bay to observe these wild bears in their native habitat, they have to be ready for anything when they come face-to-face with a group of these dangerously unpredictable bears, miles from any help. Renowned polar bear scientist Robert Rockwell ventures deep into the heart of polar bear country in search of bear DNA while conservation officers release Big Bear from polar bear jail and helicopter him back into the wild. Finally, as the days grow shorter, a local couple takes to the high seas in hopes of incorporating bears and belugas into their unique wedding ceremony.
