S1, E4: Filmed in the Arctic islands of Svalbard, Norway this beautiful program gets closer than ever before to the world's greatest land predator with the help of Icebergcam, Blizzardcam and Snowballcam. These cameras are just a breath away when two sets of cubs emerge from winter maternity dens. They also capture the moment when the sea-ice breaks away from the island in the spring. As this program captures its intimate portrait of polar bears' lives, it reveals how their intelligence and curiosity help them cope in a world of shrinking ice.
