The frozen north, where survival means constantly adapting to an unforgiving landscape. In Hudson Bay, a rare encounter between the region's top predators unfolds as wolves and polar bears clash over a single carcass - a behaviour never caught on camera until now. Under the glow of the northern lights, snowshoe hares use their large feet to escape lynx in the vast boreal forest. In Alberta, sharp-tailed grouse put on a show like never before, practising their courtship dances under car headlights. Off Alaska's coast, male walruses engage in curious vocal displays, singing together under the sunset. In summer, millions of salmon begin their epic journey upstream, while newborn caribou navigate dangerous river crossings on their first migratory trek. Life here is a series of bold moves and dramatic encounters, in a place where the stakes are always high.
