Liz Bonnin introduces a cast of charismatic animals to reveal the remarkable strategies they use to survive, and even thrive, in winter. For animals this is the toughest time of year, and preparations start early. In autumn, Siberian chipmunks collect food in their cheek pouches to stockpile in their burrows, while caribou make an epic journey to new feeding areas away from the worst weather. With the arrival of winter, the American bobcat has to find its prey beneath deep snow, while an Arctic fox must sniff out its very own frozen ready meal. A sea otter mum keeps her cub warm by blowing air into its coat, while some animals turn white to blend in with the snowy world around them. As winter begins to loosen its grip, an Arctic ground squirrel stirs from an eight-month hibernation and has to woo its mate in just twelve hours, and baby animals emerge to play in the snow before spring's imminent arrival. Along the way, Liz meets some of our most iconic winter animals to uncover the secrets behind their seasonal success stories.

The first episode tells how invertebrates became the first creatures of any kind to colonise dry land. Their forerunners were shelled and segmented sea creatures that existed 400 million years ago. Some of them ventured out of the water to lay their eggs in safety, and Attenborough compares those first steps with today's mass spawning of horseshoe crabs off the Atlantic coast of North America.
