After cleverly arranging his own kidnapping by a guerilla army leader in Cameroon, Raymond Reddington forces him to reveal that the hitman Berlin hired to kill him is the near-mythic bounty hunter Lord Baltimore. As Red heads back to Washington to plan his next move, Aram discovers that Lord Baltimore is targeting cyber engineer Rowan Mills for information to help find him. As Berlin ramps up his pursuit of Red, Rowan’s claim of innocence is undercut when the FBI finds evidence that she rented the apartment where the cyber attacks on her data files were carried out. Meanwhile, Liz Keen warns Red that the Justice Department will no longer protect the Task Force now that its director, Harold Cooper, has been sidelined.
Confronted by Liz and Donald Ressler with evidence of her complicity, Rowan admits to having a twin sister, Nora, who supposedly died in Mosul years ago, but who could be posing as her to help Berlin. But once she’s released, she returns to her childhood home where Berlin’s henchman uses a song to unlock memories that reveal she has a split personality and is really Nora - a fact Ressler soon confirms when he finds Rowan’s corpse hidden on the property. Meanwhile, after pressuring Cooper to return to duty, Red is kidnapped by a Mossad agent sent to extract him in connection with a bombing that killed an Israeli diplomat.
After Red is released on orders from the Justice Department, Aram finds that Berlin has actually hired Lord Baltimore to find Red’s ex-wife, Naomi Hyland. When Liz arrives to warn her, Naomi must tell her unsuspecting new husband that she’s in witness protection because of her previous marriage to Red. But before Naomi can be taken to safety, she’s kidnapped by an assault team led by Nora. In the wake of the attack, Liz struggles to regain her bearings and stops Nora as she is trying to escape. Using information provided by Berlin’s henchman to trigger the split personality, she forces Nora to confess to being Lord Baltimore. Finally, as Cooper returns to head up the Task Force, Berlin sends Naomi’s finger to Red and threatens to return her piece by piece as payback for his own daughter’s death.
