Medical journalist Michael Mosley introduces the fundamental questions and the great forces of history that have shaped the story of science. What is out there? What is the world made of? What is the secret of life?

This film deals with the question of our personality, an answer to such a question lies in our heads, in the brain. The brain is, without a doubt an organ that makes us who we are. It's the source of all our thoughts, emotions and abilities and yet during most of our history it was barely understood and mostly ignored until the 17th Century when medical science started to develop.
