The Bureau

Malotru is threatening to cut ties after 4 months working undercover as the CIA's mole inside the DGSE unless they take action to save Nadia.

Malotru secretly bypasses his superiors to oversee Marina's mission in Iran as she is getting closer to the son of a high-ranking Iranian official.

Arrested for Espionage by the Russian secret services, Malotru is tossed aside and left to the mercy of other inmates.

While under intense pressure from the FSB to cooperate, Malotru is focusing on finding a way out of the mess he is in.

Sisteron goes after Cyclone in Algiers while another agent contacts Malotru with potential Intel about Cyclone. Malotru struggles to maintain his cover & quickly comes face to face with Nadim, who is bent on unmasking him. Concurrently, the DGSI (General Directorate for Internal Security) subjects Marina to a tense interrogation, suspecting her to be working for the Iranian Secret Services.

While attempting to trade his Intel on Cyclone, Malotru needs to uncover Pigalle's true identity. Still on a mission to unmask Malotru, Nadim locates Prune and starts inquiring about him. Meanwhile, Marina must act quickly to keep Jérôme from going to Iran after he has been picked by Reza to accompany him there.

Kerbouche finally unveils the truth about Cyclone's life-or-death situation, which requires immediate action from the Bureau. The DGSE sets out to recruit Nadia, but Marie-Jeanne, doubtful about Malotru's intentions, is not convinced that she will accept the offer. Marie-Jeanne also sets out to teach Marina a lesson and show her the dangers of emotional attachment.

The DGSE is going through its darkest hour and launches an operation to exfiltrate Cochise and rescue Malotru as well. Meanwhile in Baku, Marina carries on with her mission for the Mossad and infiltrates the seismology's institute computer system.

The DGSE pretends to accept a deal offered by the Algerian DG, but Malotru is secretly working on a plan B to avoid their interference. Meanwhile, Malotru finds out that the Syrians have imprisoned Nadia. If Malotru wants to save her, he must cooperate. At last, Marina passes her final intelligence test - an interrogation while under the influence - and leaves the country for Iran.

At the DGSE, Sisteron is anxiously waiting for Cyclone’s release over the next few days. Malotru takes a few days off the Cyclone operation - now in the hands of the Action Division - and secretly meets up with the CIA.
