Derren Brown: The System

The System, a Channel 4 special in which Brown shared his "100 per cent guaranteed" method for winning on the horses. The show was based around the idea that a system could be developed to "guarantee a winner" of horse races. Cameras followed an ordinary member of the public, Khadisha, as Brown anonymously sent her correct predictions of five races in a row, before encouraging her to place as much money as she could on the sixth race.
