In Tokyo, there are unapproachable "lost islands" with unspoiled environs and rich wildlife. Minami Iwo-to, part of the Ogasawara island chain, is about 1,300km from the Japanese capital. Normally, entry is banned to protect the environment. An exception was made in 2017 for the first comprehensive scientific survey in 10 years. The island compresses multiple climate zones into a small area, offering researchers a rare opportunity to view evolution in action. Braving an arduous climb and a swarm of seabirds, the team discovers one new species after another.

As well as the iconic big cats, in this final episode viewers get a glimpse into the lives of the most rare and strange cats of all – including a real-life Garfield recently discovered living high in the Himalayas.
