Assisted by a mysterious smoking man, he follows the trail to ASIO, the CIA, and information that may bring down the international banking system and several governments. But he needs to find the evidence.
Kirsty is furious that Cleaver is spending so much time with Missy, but when standover man Col threatens to express that disapproval in the usual manner, Cleaver recognises that Col has a secret.
Delirious with a broken arm, Barney confesses to Scarlet that he's met someone else. Hurt and confused, Scarlet allows an innocent lunch with Harry-Sorry-David to progress down a primrose path that, with some help from Cal McGregor, will lead to perdition. Cal asks Scarlet to provide an alibi for his skipped meeting with the Premier. She does, believing it will also cover her indiscretion with David, but Cal has a darker purpose.
Some of Joshua's personal secrets are revealed in court and Missy is horrified, not only by his betrayal, but that there is now a motive for murder. Can Cleaver maintain professional standards long enough to get Missy off?
