Janet King

When a man shot dead on Australia Day marks 19 shooting deaths in the past 15 months, the attorney general asks Janet to head a royal commission into gun crime. Before she begins work on the commission, Janet finishes up an inquest into the suicide of an army corporal suffering from PTSD.

After the shooting at Elaheh's house, her family says they have no idea who would want to harm them, but Janet and Andy believe they know more than they're letting on. Meanwhile, Janet is summoned to court by her sister-in-law.

Reeling from what the ballistics report revealed, Janet lashes out at Andy, who knew all along about the gun that killed Ash. With their key witness to the illegal gun operation murdered, Janet suspects a mole in the commission. Lina convinces Elaheh to make a public appeal.

When the team discovers a link between Todd's murder and the PTSD case, Janet calls in Lance Corporal Parker and Major Hamilton for questioning. Janet meets with her paternal donor, but his position on the embryos is not what she had expected.

After discovering the cargo of illegal firearms, the commission allows the shipment to continue in hopes of finding out who will pick it up. Under political pressure from the media, the attorney general demands a report on the royal commission's progress, despite Janet's protestations that they aren't ready.

The undercover operation goes awry, with deadly consequences. Her cover blown, Bianca offers protection to Felix. Janet, Richard, and Lina prepare for their anticorruption hearing.

The commission finds a connection between Major Hamilton and Robbie Carter, the social-media face of crime victims. The attorney general gives Janet an ultimatum-either resign from the commission or risk her reputation in a public hearing.

With the commission suspended, the gun shipment is finally picked up. Janet secures damning evidence for the people involved, but without a clearance from the anticorruption hearing, all the work the commission completed could be in vain.
