Dr Helen Czerski examines the hottest natural phenomena on the planet - lightning. Bolts of lightning five times hotter than the surface of the sun strike our planet over 3 million times every day - and yet we still know little about this deadly force of nature. Now, specialist photography is revealing how lightning travels through the air, high-speed cameras are unlocking the secrets of upward lightning that's triggered by our urban landscapes, and scientific expeditions are capturing rare images of intense electrical discharges over 80 kilometres wide.

Dr Helen Czerski peers into the heart of the storm to find out how advances in technology are giving new insight into tornadoes - the fastest winds on the planet. From the breathtaking footage that capture the extreme weather events that produce them, to the latest experiments investigating their incredible destructive power, Helen discovers how understanding the subtle changes deep within the storm are improving predictions of when and where these devastating beasts will strike.

In this final installment to the series, David Attenborough travels to four unique locations about the globe where an abundance of fossilized plant and animal remains have given us a detailed picture of what life could have been like in prehistoric times. Each of the sites experienced its own set of circumstances which enabled it to preserve many perfect specimens for extraction and analysis. Piecing together the collected evidence, paleontologists have been able to determine early animal hierarchies, their diets and their evolutionary paths.

Professor David Scheel takes an octopus into his home to learn about its intelligence and the extraordinary relationship he and his daughter develop with the creature. Named Heidi, the octopus is seen unravelling puzzles, recognising individual humans and even watching TV with the family. The film also looks at the remarkable behaviour of other octopuses around the world, from those that can change their colour and texture in a split second to the octopus that carries around its own coconut shell to hide in.
