Le Bureau des Légendes

Malotru is still held captive by DAESH and the DGSE enlists Nadia to set up a risky rescue mission. Tensions mount as the CIA is afraid that Malotru's release could bring his treason to the public light. Meanwhile, Marina is still traumatized by her ordeal in Iran and is sinking deeper into paranoia.

Nadia initiates the negotiations between DAESH and the DGSE while Malotru is approached by an FSB agent working undercover as his jailor. Marina's return to the field is compromised by her growing paranoia.

Malotru's hopes are dashed when the FSB mole is hurt in combat. Marina is approached by Phillippe, who pretends to work for the DGSE but is actually working to recruit her for the Mossad.

A DAESH commander sends a coded message to the DGSE saying he is ready to defect. The Russian mole comes back with new orders from the FSB: let Malotru rot in his cell. Meanwhile, Philippe begins to train Marina and asks her to speak at a conference in Baku.

Malotru and the Russian agent must fight for their survival against the Jihadist forces pursuing them. Duflot is preparing to go out into the field in Syria to meet with Cochise, who could be his only chance to save Malotru.

Malotru must struggle on his own to survive and escape Syria. Duflot is on his way to meet Cochise. Meanwhile in Baku, Marina is offered a position at the seismology Institute.

Marina's mission is jeopardized again when her paranoia takes over again. In a tense encounter, Duflot negotiates for Cochise's defection, on the sole condition that Malotru be released.

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.

Nadia and the Bureau are pulling out all the stops to locate Malotru, who has expertly covered his tracks, as always. Meanwhile, the wind is turning for Marina in Baku when Philippe finally realizes that this mission may not be her first.

Philippe is holding Marina captive, and the Mossad is ready to finish her. Back in Paris, Marie-Jeanne finds out that Nadia and Malotru are planning to meet in secret and she is determined to use this opportunity to arrest him.
