Cameras follow a family of gorillas, with Spy Grub and Spy Fruit testing their intelligence. Elsewhere in Brazil, Spy Jaguar Cub explores a beautiful gathering of water birds, capybara and caiman, and joins Spy Caiman to film a feeding frenzy.
Spy Pup is immersed in wild dog life to explore their maternal love, and Spy Penguin records the turbulent action of the mating season, as a male Adelie penguin falls victim to a pebble thief that ruins his chances of love for the season. Spy Tortoise and Spy Bushbaby keep watch on chimpanzees, while in perhaps the most moving scenes; Spy Monkey becomes the focus of attention for a troop of concerned langurs who believe the motionless camera-creature has died.

Undercover cameras help to explore the world of animal intelligence, ingenuity and creativity in their hunting, protection and health. Spy Orang-utan meets her real-life counterparts in Borneo to capture how, living close to local people, they have gained unexpected skills in sawing wood and washing with soap, while Spy Termite catches one of the world's cleverest animal tricksters, the drongo, as he tries to outwit a group of meerkats in the battle for food.

Cameras follow Japanese macaques in the snow-covered mountains of Japan, as they gather at steaming hot thermal pools to bathe and socialise. Elsewhere in the cool mountains of Mexico, cameras capture a spectacular gathering of billions of monarch butterflies, and in Bavaria, Germany, Spy Beaver gains unique access to the secretive world of the beaver.

On Christmas Island, the Spy Crab camera walks among red crabs as they march into the sea, and in Madagascar, cameras follow many of the species of chameleon that live there. Meanwhile on Seal island off the tip of South Africa, Spy Seal Pup finds itself in the midst of the 60,000 cape fur seals that have come ashore to raise their young.

Cameras travel to the Arctic and Antarctic circles, following chicks in a king penguin colony on the island of South Georgia in the Southern Ocean. On the other side of the world, Spy Walrus discovers a walrus family hauled out on an ice floe, before Spy Gyrfalcon follows the family as they head towards dry land. Elsewhere on Norway's Hornoya island, Spy Puffin follows thousands of male puffins as they gather in the snow and search for their life-long partners.

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.
More than a billion people around the world commute into cities each day, and they are not alone. The world's wildlife is commuting too. A steady flow of animals journey in and out of cities to find food and shelter or to start a family. Leaving the wilderness they must overcome the unique challenges that the urban world throws at them to benefit from the opportunities on offer. This episode explores whether the secret to an animal's success in this fast-changing world is to keep one foot in the wild and one in the city, becoming a wild commuter. It seems that all over the world animals are finding that the city can offer opportunities that are harder to come by in the natural world. Some, like African penguins, whose population has plummeted by 80 per cent in the last 50 years, find shelter in the city. By nesting in Cape Town they are safer from predators, and with relatively easy access to their fishing grounds they have the best of both worlds. Many other animals commute into cities because they are filled with food. In St Lucia, South Africa, that includes hippos. Able to eat up to fifty kilograms of grass in a single sitting, they have developed a taste for the short, manicured lawns and come to town every night to dine out. St Lucia's human residents have learnt to give the hippos the space they need during their night-time raids. Black bears need to eat more than 20,000 calories a day to survive their six-month hibernation through winter, and using their acute sense of smell they can easily track down leftovers. In North America they come into towns and cities in search of food. Many animals displaced from their natural habitat are now using their wild skill set in the city to help fulfill their needs. Could this be the beginning of a new and very modern migration?
