S1, E5: The story continues as the spy cameras follow both sets of polar bear families. The mother with two cubs is in polar bear heaven, surrounded by ice and seals. That is, until an ocean swell makes ice travel difficult for the cubs. The other mother and cub family find it difficult to survive on Svalbard, as food is scarce. They must be clever and find emergency sources of food to stay alive. Elsewhere, a group of young, playful male polar bears play a rousing game of soccer with Snowballcam.
