In the late 1980s and 1990s, Linford Christie was probably the most celebrated athlete in the UK, having won gold in the Olympics, the World and European Championships and the Commonwealth Games. He was on track to retire as athletics royalty, but when he came out of retirement in 1999 for one last race, he tested positive for a banned substance, and suddenly his huge sporting achievements looked as though they might be swept away. In this documentary, Christie confronts his ignominous fall from grace and discusses his life and legacy - and the importance of respect and reputation in an era when social media can quickly destroy both.
