Spring arrives in the polar regions, and the sun appears after an absence of five months; warmth and life return to these magical ice worlds - the greatest seasonal transformation on our planet is underway. Male Adelie penguins arrive in Antarctica to build their nests - it takes a good property to attract the best mates and the males will stop at nothing to better their rivals! But these early birds face the fiercest storms on the planet. In the Arctic, a polar bear mother is hunting with her cubs. Inland, the frozen rivers start to break up and billions of tons of ice are swept downstream in the greatest of polar spectacles. This melt-water fertilizes the Arctic Ocean, feeding vast shoals of Arctic cod and narwhal. The influx of freshwater accelerates the breakup of the sea-ice - an area of ice the size of Australia will soon vanish from the Arctic. On land, a woolly bear caterpillar emerges from the snow having spent the winter frozen solid. Caterpillars normally become moths within months of hatching, but life is so harsh here that the woolly bear takes 14 years to reach adulthood. Once mature it has only days to find a mate before it dies! Alongside the caterpillars white Arctic wolves race to raise their adorable cubs before the cold returns.

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.

Sophie explores the world of silent communication in the animal kingdom and the human world - showing how much we can actually say without ever opening our mouths or making a noise. She reveals how some species have harnessed bacteria to generate light and how light messages are used by insects and deep-sea fish for a range of reasons, including attracting prey. Exploring how body language communicates huge amounts about us and other species, Professor Scott shows why a dog's wagging tail does not always mean it is happy and how humans can tell a lot about someone's state of mind from their posture alone. She reveals why yawns and smiles are contagious and how this can play a key role in social bonding and cohesion.
