Why would security services owner, Frank Hensley, need to engage a private investigator? Intrigued by that question, private investigator, Sonoma (Sonny) Whittington, can't resist taking the case. Early in her first night on the job, one of Hensley's security patrols is ambushed. She doesn't know it then, but the incident marks the start of a case more complex than anticipated. With the attack on the patrol a police matter, Sonny is forced to suspend work on her case for a while. To fill in the anticipated few days until the police complete their investigation, Sonny and a friend head to Sonny's beach cottage on a remote island. When a series of incidents occur soon after their arrival, she soon realises she hasn't left the Hensley case behind. It followed her to the island. As the situation there escalates, Sonny is forced to call on long-time friend, Millhaven Police Superintendent, Ben Richards, for assistance. Together, they investigate a network involving abduction, corruption, deception, drugs and a rising body count. Their ongoing challenge is to identify what is real, and who they can trust.
