When Private Investigator Connor Cratchett is contacted by a former colleague with a request for help, he can't refuse. Rupert Webb is now a racehorse trainer and suspects one of the team is causing trouble at his stables in Newmarket. The loss of his best horse to a rival trainer forces Rupert to reach out.

Connor's sister Vena is married to Rick O'Riley, founder member of the rock band Hair Razing. Recently Rick has requested space and Vena intends to give it to him. She volunteers to go undercover at Rupert's Sapphire Stables. Connor reluctantly agrees.

As Vena tries to establish the truth she discovers Rupert's son has been missing for months.

Connor and Vena find themselves in a race to solve a mystery with both Rupert's family and career at stake.
