Blakely's killer is finally revealed, but Janet discovers there's someone higher up pulling the strings - someone powerful and very close.

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 drive-by shooting at the Nobakht's, the Royal Commission focuses on the origin of George Healy's gun and the money Todd left behind - leading to a dead body and a link to Ash's murder.
