Operating as an undercover investigator for the British Horseracing Authority, Jeff is approached by the multiple-champion jockey, Dave Swinton, to discuss the delicate matter of his losing races on purpose.

Shortly after Jeff narrowly escapes a certain and grisly death, the body Dave Swinton is found in his burnt out car at a deserted beauty spot in Oxfordshire. The police think it's a suicide, but Jeff is not so sure. He starts to investigate those races that Swinton could have intentionally lost, but soon discovers instead that there are those who would prevent him from doing so, at any cost.
