This astounding documentary delves into the mysteries of the Tunguska event – one of the largest cosmic disasters in the history of civilisation. At 7.15 am, on 30th June 1908, a giant fireball, as bright the sun, exploded in the sky over Tunguska in central Siberia. Its force was equivalent to twenty million tonnes of TNT, and a thousand times greater than that of the atomic bomb dropped on Hiroshima in 1945. An estimated sixty million trees were felled over an area of over two thousand square kilometres - an area over half the size of Rhode Island. If the explosion had occurred over London or Paris, hundreds of thousands of people would have been killed.

For the first time, a documentary captures stunning footage in the midst of this demanding journey. The documentary starts at the beginning of the year, when more than two million animals gather in the shadow of the volcanoes on the southern edge of the Serengeti in order to birth their offspring. In just two weeks, the animal herd's population has increased by one third, and after only two days, the calves can already run as fast as the adults The young wildebeest in this phase of their life are the most vulnerable to attacks by lions, cheetahs, leopards or hyenas.
