Heading up a Royal Commission into gun crime, Janet King believes solving the murder of Todd Wilson will uncover what's fuelling the violence.
After the drive-by shooting at the Nobakht's, the Royal Commission focuses on the origin of George Healy's gun and the 322,000 Todd left behind - leading to a dead body and a link to a murder.
After discovering the gun used in the drive-by was used in Ash's killing and the kneecapping of gambling addict Felix Murphy, the Commission launches an undercover operation to find out who shot Felix.
The suspicion on Karen is quickly transferred to Major Simon Hamilton and continues to mount due to his missing Ferrari, abusive reputation, no alibi for the night of Todd's murder and a shipping container full of handguns.
With increasing political pressure for the Royal Commission to deliver results, and the container full of handguns so far yielding nothing, Janet is forced to fast-track the undercover mission.
Following Brett Bonar's death, the Commission discovers he was not only the shooter at the Nobakht house and involved George Healy's killing, but he also knew Ash's killer. So who is he working for?
Despite solving Todd Wilson's murder, the political pressure on Janet culminates in a dilemma: she must either step down or suspend the Royal Commission.
With her Royal Commission suspended, Janet has to fight off the State Corruption watchdog, her political enemies, and ultimately, Ash's killer.
