Members of the weasel family are often portrayed as the villains of the natural world, but do they deserve this reputation? By following the adventures of a tiny orphaned weasel named Twiz, this film reveals the true nature of these pocket-sized predators, which relative to their size have a bite more powerful than a tiger’s. In Yorkshire, a unique garden rigged with over 50 cameras gives a rare insight into the dramatic life of a mother stoat as she tries to raise her first family. And new science uncovers the problem-solving abilities of the honey badger, the secrets behind the ferret’s legendary flexibility, and the remarkable sense of smell of the wolverine. Together, using their extraordinary skills, this feisty and fearless family have conquered the planet.

In this episode Brian uncovers how the stunning diversity of shapes in the natural world are shadows of the rules that govern the universe. In Spain he shows how an attempt by hundreds of people to build the highest human tower reveals the force that shapes our planet. In Nepal, honey hunters seek out giant beehives that cling to cliff walls. The perfect hexagonal honeycombs made by the bees to store their honey conceal a mathematical rule. Off the coast of Canada, Brian explains how some of the most irregular, dangerous shapes in nature - massive icebergs that surge down from Greenland and into shipping lanes of the Atlantic - emerge from a powerful yet infinitely small force of nature. Even the most delicate six-sided snowflake tells a story of the forces of nature that forged it.

Elephant seals are the first animals to return to the beaches of the subantarctic islands in spring, forming large breeding colonies, where the males fight fierce battles to gain and retain permanent access to a large number of females. They mate with the females as soon as they are receptive again. Millions of Macaroni Penguins form huge colonies on the islands to breed.

In this episode, Iolo investigates the courtship and nesting behaviour of birds, including the amazing courtship display of great crested grebes at a reservoir near Pontypool, the impressive sky dance of hen harriers in the dramatic Cambrian Mountains, how nuthatch use mud like cement to prepare their nest in a woodland near Harlech, and why long-tailed tits near Newtown are exceptional nest builders. On the Lleyn Peninsula near Trefor, he looks at why one colony of shags nest earlier than any others in Wales, and in Pembrokeshire he finds out where house martins nested before they used our buildings. Iolo also looks at the variety of places birds like to nest, from little ringed plovers on shingle banks along the River Tywi to puffins underground on Skomer.
