Documentary telling the story of some of the most important scientific thinkers of the modern age - an epic tale of men and women obsessed by intellectual challenges but dogged by their human failings; of bitter personal rivalries, clashes of ideology and unlikely collaboration. These are the people who discovered the structure of DNA and worked out how our genes work, who changed our view of life forever. The film is an unvarnished account of the scientists who dared to discover the secret of life - told through fascinating and revealing archive - in their own words. Contributors interviewed include: Sir Paul Nurse, biologist, Nobel laureate and President of the Royal Society; Prof Lisa Jardine, historian of science, daughter of Jacob Bronowski, and hence knew many of the Cambridge scientists involved with the DNA story as a child and an undergraduate; Prof Steve Jones, geneticist, UCL.
