Laura Murray knows how bad, how rotten to the core, people can be.

Five years ago, Laura's psychic dreams helped to catch a serial killer who took the lives of four people in her hometown of Wallaby Rock.

Laura is carving out a career as a canine handler with the New South Wales Police and joins her friend, Leading Senior Constable Erica Martin, to investigate suspicious disappearances of young women across the state.

With the help of a bikie turned police informant, they close in on a human trafficking network. But as Laura's dark dreams return, the taskforce suspects they have a traitor in their midst.

A traitor who could place all they've worked for, and their own lives, at risk.
