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.

Professor Brian Cox follows Earth's epic journey through space. He takes to the air in a top-secret fighter jet to race the spin of the planet and reverse the passage of the day. In Brazil, a monstrous wave that surges up the Amazon River provides an epic ride of a different kind - chased by a top surfer through the rainforest, this tidal wave marks Earth's constant dance with the Moon. Greenland experiences some of the biggest swings in seasons in the world, but despite the deep freeze, the harsh winter brings opportunity to the Inuit people who live there. All this spectacle here on Earth signals that we are thundering through the universe at breakneck speed. Brian explains why we can't feel it and how understanding motion brings us to understanding the nature of space and time itself, leading to the astonishing conclusion that the past, present and future all exist right now.
