After testifying against his former colleagues in a corruption trial Sydney detective Jack Kempson (Colin Friels) is reassigned to a unit charged with entering the details of old cases into a police database. He unofficially begins to investigate unsolved crimes dating back many years. This case is the 1992 murder of a criminal informant who was shot at his son's football game. Jack and his partner, Samantha Lawson (Marta Dusseldorp), stop at nothing to find out who killed him and in the process find out who's behind an armed car robbery.

In 1992 a loving father was gunned down in front of his kids at their Saturday morning football game. The murder led to a series of underworld murders in what police assumed was a pay back killing. 12 years later, is it that the victim's young sons witnessed their father's brutal death that they turn to crime themselves, or was it that the police did nothing to solve his murder? Jack is faced with a dilemma when he suspects the boys are involved in a string of daring robberies. He races to close the unsolved killing before the boys seek their own retribution.
