Mark Lewis, one of Britain's leading lawyers, may have taken on one of the world's most powerful media moguls, but can he do the same with multiple sclerosis? Filmed over the course of a year, with exclusive access, this documentary follows the progress of high-profile media, libel and privacy lawyer Mark Lewis, as he participates in revolutionary stem cell trials for MS. It's a journey that will end either in medical breakthrough, and miraculous recovery, or his continued decline. At the age of 25, Mark received the devastating news that he had MS - a degenerative condition of the central nervous system, for which there is currently no cure. He is now 50 and over the last few years, Mark's condition has worsened. Mark first came to the widespread public attention as the lawyer who represented Milly Dowler's family and over 180 hacking victims in the News of the World phone hacking trial.
