After a life spent travelling the globe, the world’s most famous naturalist turns his attention closer to home to explore the wildlife of England’s iconic capital. Having lived in London for 75 years, Sir David has an intimate knowledge of the city’s natural history, and there's no better guide to introduce us to its most spectacular wildlife secrets. Captured over his centennial year, this personal and poignant film is a timely insight into how cities can become homes for wildlife as well as ourselves.

Embark with conservation ecologist Chris Morgan on a great challenge: to find and film the Siberian tiger.

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.
