Chester Newton is a successful racehorse syndicate organiser and his company, Victrix Racing, is having its best year yet. When his prized horse, Potassium, wins the world-famous Epsom Derby, Chester is set to become the next big thing in British horse racing.

But one phone call changes everything. Someone hiding behind a voice scrambler and an untraceable phone is demanding he fixes a race - and they're willing to go after Chester's family if he fails to comply. Chester's business is the only thing in his life that isn't falling apart.

With his marriage on the rocks and his children growing increasingly distant, he is not willing to let someone destroy the success he's spent his life building. Then his daughter is kidnapped and, very suddenly, it's not just his livelihood that's on the line. Now Chester must discover just how far he will go to protect his family .
