The Bureau

Malotru return to Paris after 6 years undercover in Damascus is proving difficult. He cannot forget Nadia, whom he fell in love with in Syria. He starts training Marina, a future undercover agent. Meanwhile, agent Cyclone goes missing in Algeria.

"Cyclone is still missing, and The Bureau now has to handle another exfiltration in Algeria.Malotru reconnect with Nadia but starts to question her loyalty. Meanwhile, the Bureau is cleaning Marina's past so as not to put her legend at risk."

Malotru decides to test Gherbi's loyalty by luring him into a trap. Nadia joins in on a mysterious meeting with other Syrians. Malotru finally confronts Nadia her. Marina successfully infiltrates the Paris Institute of Earth Physics.

Malotru discovers that Nadia is involved in secret negotiations and that their relationship could cost her her life. To protect her, he reactivates his legend on his own, thus establishing a hermetic seal between him and the DGSE.

Sisteron goes to Algiers to find Cyclone. Meanwhile, a certain Pigalle claims to have information on the missing agent. Marina is arrested and interrogated by the DGSI: will she hold on to her legend?

Malotru communicates with Pigalle who wants to sell the information he has on Cyclone. The Algerian officer is extremely careful. Who is he? Is he acting alone or with the approval of the Algerian secret services? He must be identified.

Kerbouche reveals that Cyclone is in mortal danger while the Quai d'Orsay finds out about the secret negotiations. The DGSE sets up an operation to recruit Nadia: will she accept to join the service?

Nadia refuses to be recruited. She doesn't want to betray her country. Devastated by Malotru's revelations, she collapses during a meeting.

Malotru learns that Nadia is locked up in a cell and Nadim offers him a deal: if he wants to save her, he must cooperate. Marina takes the last test of her legend: if she succeeds, she starts her mission in Iran.

At the DGSE, Sisteron anxiously awaits the operation to free Cyclone. Marie-Jeanne learns a disturbing news: Marina has been taken off the plane leaving for Iran.
