Temuera Morrison plays Detective Sergeant Ihaka, a no-nonsense cop in the Auckland PD. After a very public incident involving a mugger, a wounded cop and a baseball bat, Ihaka is shipped off to Sydney, Australia for a couple of weeks. He is sent to Sydney to attend an international symposium on policing techniques and finds himself partnered with Kirsty Finn, a by-the-book, "desk jockey" detective with the Australian Federal Police. One of the exercises of the symposium is to review procedures used in a past case, then report on their findings. Ihaka and Finn are given the unsolved case of the rape/murder of an up-and-coming model, from 3 years earlier. Supposedly the killer is a psycho and this was just a "thrill kill". However, during the course of their review they find evidence that was previously ignored and suddenly they aren't just reviewing the case, they are hot on the heels of the killer and up to their necks in blackmail, deceit and the upper echelon of society.
