"Lightning - it strikes at random, is five times hotter than the sun and turns sand into glass in an instant.

Lightning: Nature Strikes Back looks into the cause, effect and current understanding of one of nature's greatest enigmas.

Lightning is almost as old as the planet itself and will probably outlast life on Earth. We all experience it, yet we have a limited understanding of lightning. The program celebrates this maverick of nature, examining its generation within storm clouds, and its impact, both good and bad, on humankind.

There are first-hand accounts from survivors of lightning strikes and an assessment of how medical research is looking into its possible effect on the human body's own electrical circuit. What is the impact of human activity itself on the formation of lightning?

Looking at the application of state of the art lightning detection techniques, triggered lightning studies in Florida, filming sprites in Colorado and the lightning defences at the Kennedy Space Centre, the film tries to discover whether science is any closer to unlocking some of lightning's mysteries."
