The DGSE is unsettled when an article about Malotru's death in Ukraine gets published. They open an investigation to find out how the Intel got out. The Bureau's director, JJA, has to handle his secret agents following this leak: César, in Russia, and Mille Sabord, a new agent posted in the Middle East, are particularly upset. This whole business awakens a bunch of demons from JJA's past. After being contacted by a powerful sheikh from a tribe in Sinai, Marie-Jeanne, an agent handler based in Egypt (Cairo), is forced to work with a disturbing spy from the Egyptian secret services.

The Bureau is looking for César after he failed to catch a flight to Riga. Could he have been kidnapped? Meanwhile, Ellenstein is questioning JJA's power of judgment.

During a paper chase cleverly orchestrated by The Bureau and his friend Pavel Lebedev, Karlov slowly uncovers the vice that's tightening around him. Ready to recruit Karlov, Lebedev decides unilaterally to organize Nadia's extraction. This could sabotage the whole operation devised by JJA! The Bureau's director knows this is his last tour de force. Meanwhile, Bakatine is inches away from discovering the truth. It could all end in disaster.

Having recently returned to France, Marie-Jeanne is put back in charge of The Bureau. Sisteron, meanwhile, is managing the office responsible for handling Intel from Karlov.
