Citadel

Citadel agents Nadia and Mason follow a red herring and end up on an ill-fated luxury train. Whether they survive or not, their organisation is headed for a downfall.

When Nadia and Mason have an awkward reunion at a restaurant in Spain, they do not expect a Manticore operative to barge in and enjoy a one-sided slugfest against them.

Mason accompanies Nadia on a dangerous mission after a brief rest at a safe house. Along the way, he receives a piece of intel that can dent his faith in her.

Nadia and Kyle arrive at the Manticore compound in Morocco and risk their lives to free a former colleague; however, their hero's welcome is short-lived as they are forced to deal with a dangerous accusation.

Driven into a corner, Nadia must disclose a life-altering truth that she had been hiding from Mason; back at Manticore, Dahlia sets the wheels in motion to acquire what she wants.

When a member of their own team gets captured by Manticore, Kyle, Carter and Nadia are ready to give it their all to carry out a rescue operation and put an end to Manticore's plans to acquire the nuclear weapons.
