Nikita

Nikita, Michael, and Alex pursue the black box, which has fallen into the hands of one of Amanda's agents. The remaining members of Division find themselves in danger from potential international buyers and the President, who is prepared to send the Navy SEALs to finish off Division if they cannot retrieve the box. Reformed rogue and arms dealer Cyrus returns to Division to help the team, which has no support staff, few leads, and is facing a clock ticking. With his help, Nikita, Michael and Alex stage a daring op at the tightly-secured G-20 economic summit to regain control of the box and everyone’s future.

Alex, broken by Amanda’s programming, her inability to save everyone, and her role in tragic events at Division, reverts to her old behavior and lashes out violently. With most members of Division dead or scattered, Nikita and Michael try to sift through the remains of Division to determine who and what can be salvaged. To make matters worse, they must act quickly, before the President realizes what has happened. Memories of Division’s glory days haunt Nikita and Michael, and Birkhoff struggles with his own personal losses.

With Nikita trapped and drugged, Amanda subjects Nikita with her horrific mental conditioning process, sharing terrible memories of her own childhood with Nikita. Through the conditioning process, Nikita uncovers Amanda’s deepest, darkest secret. With Alex's role as the leader of the mutiny now out in the open, she Alex struggles to save everyone at Division as the violence escalates.

Nikita decides that Division should accept a government mission to assassinate the President of Chad while he's in Paris, but Alex disagrees with the plan and refuses to be a part of the mission. Frustrated that Nikita is keeping secrets from the rest of the group, much like Percy did, Alex asks Birkoff to dig up secrets on Danforth to use as leverage in case the government tries to shut down Division. However, Alex and Birkhoff are stunned when they uncover a secret so big it could threaten Division's existence.

Amanda holds Alex captive and offers Nikita Alex's freedom in exchange for Ari's. Michael puts Nikita and Sean in charge of the prisoner exchange, but Ryan makes a last minute addition and adds Owen to the mission, leaving Michael suspicious. While captured, Alex befriends a fellow prisoner named Larissa and vows to promises to free them both from Amanda. This promise eventually conflicts with Nikita's plan, forcing Alex to choose between Nikita and her promise to Larissa.

Hoping to gain control of the black box, Amanda attempts to kidnap Ari's son, Stefan, and use him as a bargaining tool with Ari. While still being held at Division, Ari asks Nikita to help protect his son. However, both Nikita and Amanda end up held captive by Stefan's bodyguard Krieg, forcing Nikita and Amanda to cooperate in order to escape. Back at division, Owen is upset with Michael after Michael assigns Alex to help Nikita on the mission instead of him.

Birkhoff receives a tip from Shadowbot on Ari Tasarov's location, and so Nikita and Owen travel to New York to detain him before the FBI catches him. They learn, however, that Ari planted the tip to set up a meeting with Nikita. He reveals that Amanda is plotting with a terrorist to carry out an attack on American soil, and he asks for fifty million dollars in exchange for information that would lead Nikita and Owen to the terrorist. Nikita and Michael are shocked when Ryan considers paying the bribe. Meanwhile, Sean is jealous of Alex and Owen's relationship.

Kendrick is killed shortly after receiving the hard drive, and Amanda frames Sean killing and the CIA takes him into custody. Nikita and Alex work to free Sean in a dangerous plan that could cost him his life.

Michael officially gives up his role as a field agent and resumes his previous role inside Division running Operations.

Meanwhile, Birkhoff continues to close in on Amanda's mole, and Alex starts to unravel.

Division intel reveals that a former Division agent, Markov, has reappeared after six years undercover and has become President of Uzbekistan, with plans to assassinate the President of the United States. Ryan reveals to his team that the president is already having doubts about Division's existence and has threatened to wipe them out if the public finds out about the secret agency. Nikita and Michael are furious that Ryan failed to reveal this information, and they are forced to come up with a way to save the president's life without alerting her to the life-threatening situation. Meanwhile, after Alex and Owen are caught in an explosion, an investigation leads them to believe that someone inside Division is responsible.

Owen is freed from a Russian prison by Anne, a rogue Division agent working for Amanda. He manages to escape Anne's clutches and gets a message to Nikita to let her know that he's free. Once Nikita finds Owen, he is surprised to hear that Nikita is once again with Division but returns to Division headquarters with her. Though Michael and Ryan aren't certain Owen can be trusted, Nikita stands by her friend.

Ryan takes over as head of Division with Nikita by his side. In their first mission, they must round up "The Dirty Thirty," the rogue Division agents who failed to respond to the Division recall after Percy was killed. Unfortunately, the mission doesn't go as planned and Michael is arrested in Hong Kong, forcing Nikita to change plans and devise a plan to break him out of prison.

Alex and Sean find themselves trapped in a dangerous gunfire battle with the U.S. Marines, and Ryan has to convince the U.S. President not to destroy Division until Nikita and Michael can safely escape. The President, however, is anxious to put and end to Percy's reign. Meanwhile, Birkhoff turns to Sonya for help, and Nikita corners Percy in his office, but he has one final trick up his sleeve that may prevent Nikita and Michael from succeeding in their mission.

Percy calls the U.S. President, threatening to detonate a nuclear weapon unless the president meets his demands. Birkhoff tracks down two scientists who could help stop Percy's new nuclear satellite, so Nikita and Michael pursue one while Sean and Alex look for the other. Unfortunately, Alex and Sean find themselves in the spot that Percy decides to blows up as a demonstration of his power. Meanwhile, Nikita decides the best way to stop Percy is to go straight to Division itself.

As Percy's nuclear weapons plan begins spiraling out of control, Ryan suggests they turn to CIA Director Morgan Kendrick for help. Nikita is vehemently opposed to the plan and is shocked when Michael supports Ryan's idea. The tension mounts when Nikita is proven right after they discover Kendrick has a link to Percy. Meanwhile, Sean is shot by Division agents, leaving Alex shaken.

Nikita talks Birkhoff into using 20 million dollars out of his own pocket in a scheme to bankrupt Percy and Division, but Percy ends up getting his hands on all of Birkhoff's money, which causes tension between Birkhoff and Nikita. Nikita and the group have one final opportunity to get back at Percy, but Birkhoff is arrested while trying to reclaim his money, forcing Nikita to break him out of jail before Division can reach him. While Nikita works to free Brikhoff, Michael and Alex pursue the stolen money.

Meanwhile, Percy continues to play mind games with Michael, Sean, and Alex, and pushes one of them to the brink of death.

Agents continue to get assassinated one by one, sending Division into a furious panic. Amanda discovers Percy is not only the one responsible for the murders, but has been undermining her authority with several other Division agents.
