Irishman Mark Pollock has an incredible story. After losing his sight at the age of 22, Pollock journeyed to the South Pole in a race - the first sightless person to do so.
A few weeks before his wedding, however, he had a severe fall from a second-storey window that paralysed him from the waist down, but which he survived. Undaunted, he continued to work towards finding a solution to his paralysis, through the Mark Pollock Trust, the Run in the Dark charity, and his own efforts.
Unbreakable is the documentary of his story, and its makers have just released the trailer.
Mark has been a long-term advocate of finding solutions to paralysis. The Mark Pollock Trust "believes the cure for spinal cord injuries simply requires enough of the right people having the will to make it happen."
He has spoken at the TedX conference event, runs the "Run in the Dark" event in Dublin, Cork, Belfast, London and Manchester, and is personally exploring cutting-edge technology, including a robotic suit to aid in his walking.
Unbreakable will be previewed in 13 venues across the country during October. Details can be found at the film's website, markpollockfilm.com.
