Charlie Elmore suffered a brain injury in a snowboarding accident four years ago. Now she's going to retrace the steps of her dramatic recovery and meet other young people adjusting to life after serious brain injuries, including 19-year-old car-crash survivor Callum, avid skier Tai and fashion buyer Hannah, who has to re-learn how to walk and talk after she collapsed whilst out shopping and hit her head on the pavement. With their help, Charlie embarks on a courageous journey to improve understanding of this 'invisible' disability, which is the biggest cause of acquired disability in young adults in Britain, and discovers the hidden ways it affects her own life too.

Professor Shapiro shows us how some images can prompt two, or even three, equally valid interpretations. Rather than settling on one interpretation, our brains tend to switch among all of them – leading to some baffling and astonishing visual experiences.
