As the Arctic changes faster than ever, a team of polar bear guides prepares for an epic journey; a first-ever attempt to follow the bears on the sea ice of Hudson Bay. In this high-stakes high-reward venture, they will document the secret world of bears, a mysterious and disappearing realm that is the bears key to survival. Life on the ice is a critical time for these bears. It also remains undocumented, deemed too dangerous for humans to follow, hinted at only through aerial reconnaissance and satellite collar research. The team, armed with traditional ecological knowledge and the latest 4K camera technology, will witness never- before-seen seal hunting strategies and document rapid adaptations to climate change, including whale predation and open-water hunting.

The Great Lakes, home to a fifth of the world's fresh water and the backbone of a vast ecosystem, are explored from every angle on this documentary series.
