She was pretty, mid-twenties maybe, but painfully thin. She stood in front of John McBride in the gallery full of his paintings. She was trying to palm a note in the act of shaking his hand. Later when he opened the note he learned she was a prisoner in a quasi-religious Cult a four-hour drive from Sydney. McBride loved adventure, and he set about finding out more. He tracked down the cult, found out the background, tried to visit and was met with a man carrying a rifle, threatening to use it. A fire which burns down the wooden premises used by the cult are witnessed by McBride during a recce.
But McBride is under surveillance himself by the founder of the Cult, a pedophile with a long prison history and a life of luxury. McBride is kidnapped by him and abandoned on an uninhabited island. As an ex-SAS soldier it takes him only a few days to build a raft and get back to the Australian mainland. McBride has one aim: to catch the founder of the Cult, and bring him to justice.
