With Quinn at the helm, the PBI move in on Osman's men - but soon find themselves running in circles. As Janina and Lemmer join forces to unveil the truth behind the diamond-weapon exchange, Teliha's true role in this intricate, terrifying plot begins to reveal itself. Meanwhile, Milla's loyalties to Lucas, the PBI, and her son are tested - and shocking new information about Flea's death comes to light.

With Osman in a coma, Daoud takes over the the diamond exchange; Flea appeals to Lemmer for backup; Janina makes a discovery about the PBI.

Lucas becomes the PBI's main suspect in Inkunzi's murder; Janina seeks help from the CIA; Milla scrambles to uncover who Lucas really is; Lemmer continues to search for Flea and his stolen gun.

As Lucas chases down his carjackers in pursuit of a bag of stolen cash, he dogs Inkunzi for answers – and later, Milla's research puts her on Lucas's tail. After conferring with Ehrlichman in Zimbabwe, Lemmer finds himself a few steps behind Inkunzi in a quest to track down the elusive Flea, while the PBI attempts to nab Flea – and her blood diamonds – for themselves. Amid ongoing surveillance of Osman and Daoud's plans – and under pressure to locate the ominous shipment approaching Cape Town's shores – Janina considers Quinn's proposal to seek help from the CIA.

As Lemmer, Lourens, and Flea drive on with their new cargo, Lemmer notices a car on their tail that promises to cause trouble. Still under threat of an agency shutdown, Janina continues to pursue all possible leads – and Milla proves herself to be a valuable asset, despite distracting threats from abandoned husband Christo. After armed and dangerous heavy-hitter Inkunzi fails to intercept Osman's blood diamonds – which Flea had stashed in a fake rhino horn – Raj's surveillance leads the team to a heated meeting between the two men. Later, Lucas Becker, an American, gets violently carjacked in Cape Town.

In rural Loxton, South Africa, Lemmer reluctantly embarks on a shadowy smuggling operation. Meanwhile, Cape Town's Presidential Bureau of Intelligence launches a high-stakes, covert investigation into a terrorist plot after a police informant blows the whistle on a meeting between local Islamic extremists and Suleiman Daoud, a senior Al Qaeda operative. As PBI chief Janina Mentz carefully directs the sting, special agent Quinn is eager to make an arrest – and Milla, a housewife who's escaped an abusive suburban existence, lands a job as a researcher on the team.
