In the opening episode of Citadel Season 2, we're introduced to Maxwell Montaine's lavish boat party, where an uninvited guest bribes the security guard to gain entry. The mysterious guest fights his way through the crowd and into the VIP section, where he confronts Maxwell and forces him to reveal Paulo Braga's location and the fact that the cargo he helped smuggle out of the US was Bernard Orlick.
In France, Braga is forcing Orlick to help him develop a chip that he plans to insert into Arnaud's brain. They interrogate him about his brothers Raphael, Mael, and Louis. The next morning, Braga takes Orlick into the forest where Joana and Arnaud's brothers are waiting. They activate the chip briefly, taking control of Arnaud's brain and causing him to kill his own brothers. Braga claims that he targeted them because they stole oranges from his farm. After Arnaud kills his brothers, he regains consciousness, revealing that the chip still has flaws, so Orlick must continue working on it.
In Germany, Nadia Sinh is hiding out with her daughter Asha, who is resentful of not being with her grandfather and complaining about a baby crying next door. Suddenly, the baby stops crying when a Manticore operative discovers their hideout. A fierce fight breaks out, and Nadia and Asha barely escape with their lives. Asha asks her mother to teach her how to fight so she can help next time they are ambushed. This breaks Nadia's heart.
In Sweden, Mason Kane is hiding out with his wife Abby. They are both struggling to accept his identity as a spy since she knew him as Kyle Conroy. Their daughter Hendrix is with Orlick's family, which is causing tension between Mason and Abby. Back in France, Braga learns that the Russian president, Dmitry Aronov, will attend the G8 summit in Scotland in ten days. He gives Orlick an ultimatum that the chips have to be ready in ten days or else he will find his daughter and kill her. Braga then leaves for Paris with his son Edgar, Joanna, and some security guards. Taking advantage of a mistake Braga makes, Orlick manages to force a guard bringing him food to open the door and escape.
He receives a last-minute lifeline from the enigmatic man named Hutch, a rogue CIA operative who went off the grid after Braga attempted to take down a woman he cherished, all because she discovered his secret in funding European terror cells. Hutch persuades Orlick to join forces, but they realize they can't go it alone. Orlick emphasizes the need for more like them - isolated, scarred, outcasts, even psychopaths, but fiercely loyal. Hutch has a few names in mind. Back in Germany, Nadia enlists Frank Sharpe, a cunning con artist she trusts to craft new identities for Asha and herself, allowing them to vanish and pursue Manticore. Frank claims he's a "radioactive" figure, implying no one dares to work with him anymore. However, at the episode's climax, Frank shocks Nadia with a revelation: the mole who leaked information to Dahlia Archer, his own mother, was Mason Kane - the man she wed.
