In a very intimate story, broadcaster and political journalist Andrew Marr is on a mission to understand the mysteries of the human brain and to achieve further recovery after suffering a life-threatening stroke four years ago. Andrew quickly regained his ability to speak and was able to resume work after his stroke, but he is still frustrated by lack of movement in his left arm, hand and leg. Andrew meets some of Britain's million stroke survivors and travels the world in search of a miracle cure.
