After 4 months working undercover as the CIA's mole inside the DGSE, Malotru is threatening to cut ties with the Americans unless they take action to save Nadia, who is still held prisoner.
The Bureau is orchestrating an operation to recruit Sabrina, the French Jihadist's sister. Meanwhile, Marina tries to learn more about Shapur's professional life, unaware that he is being watched by the Pasdarans.
When Marina's mission becomes compromised, she is exfiltrated to Paris and forced to distance herself from Shapur, which means Malotru loses his only leverage with the CIA to secure Nadia's rescue.
The DGSE no longer knows whom to trust with its missions and its agents. Malotru's double game backfires and Sisteron is on the front line for a risky mission.
Sisteron's critical situation becomes the priority at the DGSE, where the hunt for the CIA's mole is still ongoing. Malotru is assigned to a new mission to help neutralise the French Jihadist.
Shapur's carelessness puts Marina in serious danger. Meantime in Paris, the DGSE is holding the CIA accountable and demanding to know their mole's identity.
In Iran, Marina is being transferred to another prison. Meanwhile in Raqqa, Malotru is bent on bringing an end to his mission and finds himself waiting to meet Toufik with Schnabel.
