Josh and Lawson go out to bait the Marauder bikies and which will likely bite them in the bum once Charlie finds out. Meanwhile, Stella assists a journalist who's life could be in danger.
Michael Sandrelli has been a busy man since being fired from TR. Thanks to the squad's head honcho Kerry, he's now undercover, and his job is to bring down a family of cocaine importers.
Michael fights for his life as the team ramp up their pursuit of the family they believe is responsible: the Raineys. But TR aren't the only ones with an interest in bringing the Raineys to their knees.
With help of Rainey, the team looks for the Russians who are transporting explosives and keeping Urie hostage. Joshua takes leave to go after the person he believes shot Michael.
