Several months after the shooting, Annie is out of the woods but still in the process of recovery. Not one to just sit around nursing her wounds or her broken heart, she's fixated on finding Lena, who has fled to Russia. Despite Joan, Arthur and Auggie all urging her to focus on healing, not hunting down her former boss on a personal vendetta, Annie is determined to follow a lead in Moscow. And when Joan realizes that Annie is heading to Russia whether she has permission or not, she reluctantly agrees to help in an effort to help keep Annie safe.
Though Annie's mission sounds simple enough-make contact with a former FSB operative Dmitri Larionov (codename: Rachmaninoff), convince him to lead her to Lena, and take a photo proving Lena's presence in Russia to help facilitate extradition talks - heading to Moscow alone is a risky move, and nothing is as simple as it sounds. Annie's first challenge is to convince Larionov, who was once betrayed by Lena and is allegedly out of the spy game, to help her. Thanks to Annie's doggedness, Dmitri agrees to set up a meeting with an old contact who knows Lena's whereabouts. But even with that valuable intel, getting to her won't be easy. As Annie soon learns, Lena is always two steps ahead-and going up against her will take all Annie's spycraft, skill and strength.
