Leonardo da Vinci is well known for his inventions as well as his art. New evidence shows that many of his ideas were realized long before he sketched them out in his notebooks-some even 1,700 years before him! Of these “inventions” Leonardo never affirmed that his projects came from his original ideas. The film features drawings of his most famous ideas and inventions some of which trace their original creation to ancient Greece while others were a product of the scientific inventions of golden age of Islamic learning. This knowledge seemed to be lost in Europe during the Dark Ages until the Renaissance when Leonardo recovered it.

Professor Sue Black is joined by Silent Witness's Emilia Fox to reveal the secrets of forensic science. Sue shows how the stories of our lives are hidden in the very fabric of our bodies by examining an archaeological skeleton, using techniques she uses in modern-day forensic investigations. She gradually builds up its identity until a pile of old bones once again becomes a real person. She explains how extraordinary clues in our bones can reveal everything from our age and our sex to our diets and our ancestry – there's even a bone in our ear that can reveal where our mother lived while she was pregnant. Professor Black's investigations into the trauma marks visible in the 1,000-year-old skeleton's bones reveal where this person died, and how they died. In the process, she tells this individual's extraordinary life story and sheds light on one of the darkest days in English history. The Christmas Lectures date back to 1825 when Michael Faraday founded the lectures for children at the Royal Institution. They are the world's longest running science television series, which today use demonstrations and interactive experiments with the live theatre audience.
