In this three-part BBC series, Dr Adam Rutherford tells the extraordinary story of the scientific quest to discover the secrets of the living cell. The first part, The Hidden Kingdom, explores how centuries of scientific and religious dogma were overturned by the earliest discoveries of the existence of cells, and how scientists came to realise that there was, literally, more to life than meets the eye.

The second part, The Chemistry of Life, episode explores how scientists delved ever deeper into the world of the cell, seeking to reveal the magic ingredient that can spark a bundle of chemicals into life. Their discoveries have brought us to the brink of being able to create life for ourselves.

The third and final part, The Spark of Life, reveals how our knowledge of cells has brought us to the brink of one of the most important moments in history. Scientists are close to repeating what has happened only once in four billion years - the creation of a new life form.
