Polar Bear Town

To bolster his business, Dennis plots an epic expedition over impassable tundra to an undiscovered denning site. At an exclusive denning lodge, Kelsey witnesses the rare first steps of newborn cubs emerging from their den.

This season kicks off with summer in Polar Bear Town. Tourists flock to town to see thousands of beluga whales crowding the bay, but this year, an increasing number of bears have arrived in town earlier than usual. While it may prove to be lucrative for the guides who take tourists to see polar bears, it makes life much more dangerous for locals. Guide Dennis is thrilled at the prospect of a second summer bear season, but when his No. 1 client wants to get a risky picture of a swimming polar bear above and under the water, he gets worried. The lure of a polar bear bonanza also brings Kelsey back to Churchill, but when he happens upon a mom and cub swimming toward town, he steps in to try to keep them from getting too close. If the bears reach their destination, it could be disastrous for them – and the locals. At the Mile 5 Dog Sanctuary, Brian Ladoon is set on protecting his dogs from swarms of summer insects, but a tragic bear incident catches him off guard.

After a large polar bear known as Big Bear kills one of Brian Ladoon's dogs right in town, the community is on edge. Everyone wants this bear found before another victim is claimed. Conservation is on high alert while Dennis and Andrew use night-vision cameras to look for the elusive bear; if they can identify Big Bear's path into town, it could help in catching him and keeping both the bear and the community safe. While locals try to avoid the bears, Kelsey and his crew have found a way to get closer to them – in a rundown cabin on the shores of Button Bay. After a sudden storm means an overnight stay for the group, the dilapidated shack is the only thing between them and waves of migrating polar bears.

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.
