The 'Whizz-kid' is Jack Burton, a boy from the Goldfields' town of Kalgoorlie, who wants to be an apprentice jockey. Almost jokingly, Jack's father 'Boy' Burton, suggests that career path, and then has to stand back and watch his son's introduction to the world of thoroughbred horse racing, which is both dynamic and dangerous.

Featuring in the passing parade of characters from the 'Sport of Kings' are the Stewards, who make and enforce the rules, and the cheats and criminals who try to bend and break them. There is also the state's biggest owner- breeder, and a range of horse trainers; some who are just starting out, others who are struggling to survive, and one who is making a comeback at 71 years of age and relishing getting 'another chance'.

Into that 'heady' mix are thrown a crusty newspaper Editor and his young protégé, the staff of a chemical analysis laboratory, private investigators, lawyers and two brothel Madams, from opposite sides of Australia, who have very different attitudes, agendas and perspectives on life.

Towering above all of that are the horses, which all have their own unique stories. Named after popular songs, playwrights and a surfing beach in South Africa, they all have one thing in common. They have the courage to run fast, and do so, especially for apprentice jockey, Jack Burton, the 'Whizz-kid'.
