Luminous beings, creatures with their own internal light, enchant and astonish us. Anyone who has seen a firefly or a glow-worm cannot help but fall under their spell. The sea at night sparkles as millions of luminous plankton reveal the shapes of dolphins in a truly magical light show. But why do animals produce living light? For centuries we could only marvel at the beauty and the mystery, but now for the first time we can begin to reveal the amazing truth about living lights. It has taken three crucial technological breakthroughs. Firstly, colour cameras have improved dramatically; they are now over 4,000 times more sensitive than a decade ago. The cameras are so sensitive they are revealing startling discoveries that until now we could not see. Secondly, scientists have entered the unknown world of the boundless deep open ocean with the help of a new generation of submersibles and robots. Thirdly, Ammonite Films have invented and built a series of unique cameras that can capture the faintest ephemeral glow of luminous life. By combining these three innovations, this film shows creatures and behaviours never seen before. Sir David Attenborough is our guide as we venture into a new hitherto unseen world. Bioluminescence is everywhere: in the soil, on the land and throughout the oceans. Join Sir David Attenborough and a team of the world's leading scientists and deep sea explorers on a quest to reveal the secrets of living lights.

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.

The next programme deals with flying insects. It begins in Central Europe, where the Körös River plays host to millions of giant mayflies as they rise from their larval skins to mate. — the climax of their lives. Mayflies and dragonflies were among the first to take to the air about 320 million years ago, and fossils reveal that some were similar in size to a seagull. Damselflies are also looked at in detail.

With the help of some surprising creatures from around the world, this series sets out to discover how animals take to the air, defying the force all airborne animals must conquer, gravity. Part 2: Masters of the Sky This episode looks at powered flight, revealing why peregrine falcons can top 200 miles an hour, how a hummingbird is a slave to its own rather manic lifestyle and that the albatross's secret to flying for free is its nose. Heavyweight beetles break the rules to find love, a devious sparrow-hawk uses agility to execute a lightning-fast raid on his prey and half a million mother bats dominate the sky above, and below, the ground with a dazzling display of aerial prowess.
