Steve Backshall begins his global journey at the top of the world when he boards an Arctic icebreaker and goes in search of the Arctic's top predator, the polar bear. Paddling in his kayak Steve gets first hand experience of what it's like to be a ringed seal, the polar bears favourite food, when an inquisitive bear starts to stalk Steve and gets much closer than he dares hope for. One polar bear is frightening enough but when a bunch of boisterous walruses, with their dagger-like tusks also decide to investigate Steve in his bright orange kayak, it's time to move on in search of Arctic predators.
