An extraordinary documentary on the brainpower of Daniel T, the young Englishman who could be the world’s greatest mental athlete. Daniel is not just a calculating wizard, but also a memory champion and super linguist. He speaks nine languages.

Daniel, the oldest of seven children, has been able to do amazing calculations after an epileptic fit when he was 3 years old. He was even able to remember over 22,000 numbers in a public display of his ability. But how does he do it? Leading scientists explore the extraordinary world of this real-life Rainman. Daniel’s psychological make-up is explored by Cambridge University autism expert Professor Simon Baron Cohen who delves into his childhood experiences in an effort to explain his remarkable abilities.
