Stéphanie, aided by her cousin Élisabeth, is growing increasingly confident in her role as an infiltrator, even though her plan to have Manu produce a sophisticated fake undetectable by him risks betraying her. Dominique is haunted by his past and makes heartbreaking decisions. A mix-up during Daji's exfiltration puts Bernard in hot water when Jordan, an emissary hired by the Gulf Emirate government, forces him to take drastic measures to get out of the situation. Patrice, intrigued by Daji's fate, meets Safia.

Just when Stéphanie believes she's on the verge of proving that EFEK is creating incredibly sophisticated fakes, her infiltration is compromised. The pressure mounts to conceal the truth about Daji Saeed.

Stéphanie, who is struggling to break ties with Manu, has no idea that someone is trying to eliminate her. The countdown is accelerating for the EFEK team, who are failing to complete their mission.
