Two otters, a mother and daughter, are inseparable as the cub faces the dangers of her first Scottish winter, and Mum works hard to ensure both survive. Never more than a few feet apart, cub and mum exhibit a very special relationship as the cub grows up, learning how to fish and fend for herself on the idyllic west coast of Scotland.

In a seasonal special, Gordon Buchanan meets the animals who live in nature's winter wonderlands. He reveals their survival secrets, from the polar bear mother who gives her cubs the best possible start in life to the owl that finds food hidden beneath a blanket of snow, plus the plucky penguins that huddle together to keep warm. Gordon also unwraps the lives of our favourite Christmas characters - those wonderful reindeer and our very own robin redbreast!
