But Tony is dying, and comes to Melbourne to settle an old score, and blackmail an inheritance for his son - but he is murdered in the process. Greg feels that he has no choice but to avenge his father's death - even at the cost of his own life. He arms himself with a rifle and hunts down the man he believes was responsible for the murder - and the Homicide team races to stop him. Notes: 90 minute episode.
