 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.
