As the bomb squad work to defuse a dirty bomb threatening the heart of Melbourne, Lawson, Shannon and Christian are tasked to fly to Fiji to extradite South Korean national Kenta Tomi back to Australia.

But when he doesn’t willingly hand over the code, Lawson may need to take desperate measures to get it from him. In the midst of this catastrophic threat, the team also contends with the emotional fallout of Josh’s disappearance and Michael’s death.
