This is the breathtaking story of Daniel Tammet. A twenty-something with extraordinary mental abilities, Daniel is one of the world’s few savants. He can do calculations to 100 decimal places in his head, and learn a language in a week. This documentary follows Daniel as he travels to America to meet scientists who are convinced he may hold the key to unlocking similar abilities in everyone. It appears Daniel is doing math, without actually having to think, through a process of perceiving patterns in numbers. As one Brittish onlooker stated, "It‘s godsmackingly brilliant!"
