Le Bureau des Légendes - All Seasons

After 6 years undercover in Syria, agent "Malotru" is called back home. He will face the difficulty to forget his undercover identity, the disappearance of a colleague in Algeria & the training of a young girl.

Malotru is now a mole working for the CIA within the DGSE, delivering classified information to Dr. Balmes, during fake therapy sessions. In exchange, the CIA has promised to rescue the love of his life, Nadia, now imprisoned in Syria.The pressure increases when a French jihadist threatens France with a bloody massacre.Meanwhile, Marina Loiseau begins her own clandestine mission in Iran.

Malotru has been taken hostage by the "Islamic State" and the Bureau faces a dilemma: should they use all their resources to save Malotru, who betrayed them and his country when he became a double agent working for the CIA?

Relentlessly tracked down by the CIA and the DGSE, Malotru is hiding out in Moscow where he is forced to collaborate with the Russian secret services. Back in Paris, the Bureau is in the firing line of JJA, the new Director of Internal Security. Nevertheless the Bureau launches a new, large-scale operation consisting of sending a secret agent to infiltrate Russian hackers in Moscow.

Head of Internal Security, JJA, has been promoted to the post of director to put some order into the Bureau. Meanwhile, Marie-Jeanne has decided to get away from Paris to see how well she'll fair working on the ground in Egypt.
