David Attenborough chronicles events during a sponsored nature expedition on tour of West Africa. In September 1954 David Attenborough, cameraman Charles Lagus, Jack Lester and Alf Woods, both from the Zoological Society of London, set out for Sierra Leone. They spent three months intently surveying the landscapes of Sierra Leone in search of nature’s rarest animals. Although predominantly searching for Picathartes gymnocephalus (the White-necked Rockfowl) they hoped to take back to London a representative collection of the whole of animal life in this part of Africa.

David Attenborough travels to Meru National Park in Kenya to visit Joy and George Adamson and meet Elsa the lioness and her cubs shortly before Elsa's death. In the late 1950s, game warden George and his wife Joy became the carers of three orphaned cubs - Elsa, Big One and Lustica - after George had been forced to kill their mother. Big One and Lustica were eventually sent to Rotterdam Zoo in the Netherlands, but Elsa remained with the Adamsons. Joy's quest to train Elsa to survive in the wild and Elsa's subsequent independence became the basis for the book and film Born Free. Now living in the wild with her own three cubs in Meru National Park, David joins the Adamsons as they try and track down Elsa to check up on her wellbeing.

David Attenborough's Zoo Quest in Colour Thanks to a recent remarkable discovery in the BBC's film vaults, the best of David Attenborough's early Zoo Quest adventures can now be seen as never before, in colour, and with it the remarkable story of how this pioneering television series was made. First broadcast in December 1954, Zoo Quest was one of the most popular television series of its time and launched the career of the young David Attenborough as a wildlife presenter. It completely changed how viewers saw the world, revealing wildlife and tribal communities that had never been filmed or even seen before. Broadcast ten years before colour television was seen in the UK, Zoo Quest was thought to have been filmed in black and white, until now. Using this extraordinary new-found colour film, together with new behind-the-scenes stories from David Attenborough and cameraman Charles Lagus, this special showcases the very best of Zoo Quest to West Africa, Zoo Quest to Guiana and Zoo Quest for a Dragon in stunning HD colour for the very first time.
