For most people the equator is just an imaginary line running 25,000-miles around the globe. But the countries along the equator are among the most troubled on the planet. In this new series Simon takes a journey around the region with the greatest natural biodiversity and perhaps the greatest concentration of human suffering: the equator. In Equator Simon meets illegal loggers, father and son circumcisers, drunk villagers, and a young woman stuck in the baking desert. Simon and the Equator film-crew are protected by soldiers in a coca field, and UN 'peace-enforcers' in a gold mine. They are blackmailed and abandoned by drivers in one country, and travel through another that has just 300 miles of paved roads - despite being the size of Western Europe. Simon is drenched while white-water rafting, surrounded by a million flamingos and swallowed by a tidal wave. After being warned about the deadly virus Ebola, Simon vomits blood and develops a temperature of nearly 40C.
