BlackJack: Sweet Science (2004)

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.
