There are forces in the world that are unseen. They are within us and around us, they affect the way we grow, develop and behave-and yet most of us have little understanding of them. Natural Mystery travels the globe to find the truth behind some of the world's most startling and enigmatic phenomena. Combining dramatised recreations of nature's mysteries with the latest scientific knowledge from around the world, the programmes construct a dramatic new picture of nature and its forces and explore such questions as why people are more likely to die near midnight, how animals can trace their owners and the effects of the full moon on people and animals. Presented by Lyall Watson.
