Using pioneering seamless filming techniques, each film explores magic moments when Earth bursts into life - fleeting windows of time when the conditions are just right and animals spring into action.From the rush hour just before dawn in the Kalahari, as desert creatures dash to beat the morning heat; to the hour after the rains in the Amazon, when the forest fills with activity; and from the hour of high tide in the Australian coral reef, this series takes the audience on a mesmerising cinematic journey through nature's most extraordinary moments. This is natural history on a deadline.
