Freelance journalist and single mother Hannah Webridge is commissioned by a national newspaper to write an investigative article on the notorious red light district in Kings Cross. There she meets prostitute Princess, and police inspector in the vice squad, Tom Jordan. When Princess later arrives on her doorstep beaten up so badly she is barely recognizable, Hannah is drawn ever deeper into the world of deceit and violence. Three sex workers are murdered, their deaths covered up in a media blackout, and Hannah herself is under threat. As she comes to realize that the taste for vice reaches into the higher echelons of the great and the good, Hannah must expose the truth—and stay alive.
