Whether working at the laboratory she adored in Paris or toiling at a university in London, Rosalind Franklin feels closest to the science, those unchanging laws of physics and chemistry that guide her experiments. When she is assigned to work on DNA, she believes she can unearth its secrets. Rosalind knows if she just takes one more X-ray picture --- one more after thousands --- she can unlock the building blocks of life. Never again will she have to listen to her colleagues complain about her, especially Maurice Wilkins, who would rather conspire about genetics with James Watson and Francis Crick than work alongside her. Then it finally happens --- the double helix structure of DNA reveals itself to her with perfect clarity. But what unfolds next, Rosalind never could have predicted.
