When the Machine produces the social security number of a judge renowned for his tough sentencing, Reese and Finch have the added challenge of investigating a POI who wants nothing to do with their brand of vigilante justice.
Mr. Reese goes as the new driver of fixer Zoe Morgan in order to decide if she's a victim or perpetrator. When Zoe listens to a recording she isn't supposed to, she becomes the target of a pharmaceutical company.
Reese works the computer while Finch does the legwork with their latest POI, a building super who keeps too close an eye on his tenants. Meanwhile, Detective Carter may finally get her long-awaited glimpse into a case.

The FBI are getting closer to the head of HR. Mr. Reese tries to prevent a young journalist that likes taking risks from being killed. To avoid getting media attention, Mr. Reese starts dating her. Fusco is playing double.
Reese and Finch's latest number is twenty-six year old Abby Monroe, who they expect will be the target based on basic information they have about her. She is a past honor student having received a degree in engineering. She worked the past year for Homes for Our Returning Heroes, a military charity that supports returning veterans financially, that job Reese and Finch surmise in honor of her brother who was killed in Afghanistan. She, however, left that job to work instead for the city planning department. Their belief that she will be the target does not diminish when they and Carter find out that she was fired from the charity for stealing, that she committed a minor theft while at the planning department, and that she is associated with a veteran name Shayn Coleman, who too has committed some major thefts of late. Abby seems like she has been trying to live off the grid for the past week, leading to their belief that she is running away from someone or something. When Reese and Finch catch up with Abby and Shayn and discover what they're up to, they have to decide what to do based in part on the illegal nature of their plan. Meanwhile, Donnelly offers Carter a temporary secondment into the FBI, with the job having the strong possibility of being permanent. The secondment is specifically to work on the "suited man" case, with Donnelly and his team getting new information about John and his whereabouts. Detective Beecher wants to pursue a relationship with Carter about which everyone seems happy except Fusco, who doesn't yet trust him. And Fusco keeps an extra eye out on HR's activities as he is worried about his own connection to Davidson's death.
Special Agent Donnelly has Reese, along with three other men, in seventy-two hour custody on Riker's Island. With Finch's help, Carter is in unofficial charge of helping Reese get out of custody without disclosing to Donnelly that Reese is indeed the "man in the suit" that Donnelly considers the most dangerous man on the loose. Although Carter has a plan to do so, she may find that tenacious Donnelly may not let Reese and the other three go so easily if he has not yet found out which one is the man in the suit. Meanwhile, Finch, largely with Fusco's help, is handling their next number, that of Brooklyn high school student Caleb Phipps. Caleb is an average student and comes from a poor family, living alone with his single alcoholic mother, whose drinking problem may stem from the grief over the death of Caleb's older brother, Ryan, two years earlier. Ryan, who was with Caleb at the time and who witnessed the incident, was pushed into the path of a subway train, although official reports state that he fell onto the tracks accidentally. Caleb seems to be having problems with the drug dealing gang at school, who may be targeting him. Finch also learns that Caleb's average grades masks the fact that he is a mathematical genius. In uncovering the reason why Caleb hides his genius, why the accident report on Ryan's death was a manufactured lie by the transit cop, and what Caleb's connection to the drug dealers is, Finch may find out who Caleb is the target of, or conversely who he is targeting.

Nobody knows where the Machine has now relocated itself, but it is still in contact with both Finch and, by association, Reese and their new partner Shaw, as well as Root. Still institutionalized, Root may have a short term problem in dealing with her psychiatrist, whom she sees as being stupid, and from whom she has not been provided access to any electronic devices including telephones. Carter, now demoted to patrol following her HR-initiated wrongful shooting incident, has her own new primary agenda. She has also not told Finch or Reese of her association with a past number. And the Machine has dispensed another number to Finch, that of navy sailor, petty officer second class Jack Salazar. Upon first sighting, Reese, despite or partly because he chose the military over a prison sentence for an assault five years earlier, likes Salazar, a man who seems to stand up for his principles and his friends and who knows how to take care of himself using his fists. After Reese loses track of him, he may be difficult to relocate since he is one of approximately 4,000 sailors in town for the day on fleet week. They will learn that the Machine-identified situation in which Salazar is involved is in part related to his recent activities off the coast of Africa, those activities for which others are highly interested without his knowledge.
The head of an Internet company ostensibly for finding lost loved ones is really a front for selling personal info. Carter has to train a new cop while she looks for Beecher's killer and a new vigilante named Collier makes his appearance.
The next number the machine dispenses is for Vanessa Watkins, a hard-nosed prosecuting attorney who, when Finch and Reese first meet her, has just reported her husband, Jeremy Watkins, missing from their yacht. While Vanessa has put away many a criminal over her storied career, Jeremy has let many go as a flashy and high-priced defense attorney. As her number came in after the report of him missing, they know Jeremy's presumed death is not the reason for the number, yet they don't know if Vanessa is the target or the perpetrator. They learn that the lead investigator on the case of Jeremy's death, Detective Cameron, is looking at her for her husband's murder as all evidence found thus far implicates her. Cameron's main problem?: he doesn't have a body, and thus needs Vanessa to confess to make a conviction stick, which she may or may not know. They will also learn that Cameron has a personal vendetta against her, which places a major obstacle in tracking her as she tries to elude Cameron. As Finch and the team wade through the story of the complicated lives of Jeremy and Vanessa - including their unlikely personal coupling - they find that Vanessa knows her law and is resourceful and strategic in her every surprising move. They may not learn if she is the target or the perpetrator without getting the story directly from her. Even then, as she is a lawyer who knows how to spin, they have to act the judge and jury in their own court of opinion in evaluating her story. Meanwhile, as Carter assists them on this case, she finds that she has to be careful around her new rookie partner, Laskey. She doesn't yet know how careful she truly has to be.

News of Northern Lights has hit the media, meaning that the team's work has become more difficult if only because of the public eye on what is happening. While Shaw heads off with Root on her next assignment, Reese heads to Washington DC to reunite with Finch for their next number, that belonging to Illinois Congressman Roger McCourt. Finch's initial guess is that they are heading into uncharted territory as he believes that McCourt is not only the target or the perpetrator of an individual crime, but also that his number is related to terrorism or national security regarding Decima trying to get Samaritan up and running, which, if happens, means the end of their own lives. McCourt sits on the Rules Committee which controls legislation. He has been an outspoken opponent of government surveillance, and thus could be a target for Decima as opposed to Vigilance. They learn that McCourt likes to see himself as a deal maker, one where all sides end up happy. When Reese eventually learns why the Machine provided his number, Finch, Reese and Shaw know that they truly are moving into uncharted territory as they come across a moral dilemma about what to do in the situation.
Decima has completed its beta test of Samaritan and has now shut it down temporarily as Greer has to get the politicos, namely Garrison, to buy into the need to purchase it in the name of national security. Greer needs this to happen as they require the government feeds for Samaritan to operate properly. With Finch now being held by Greer and Decima, Reese believes that their first priority should be to retrieve him. However, Root, in her continuing contact with the Machine, convinces Reese and Shaw that the Machine is telling her that Finch, for the time being, is safe, and that they have to deal with the next number. As the Machine does not have an overall picture of what will happen, it provides five numbers for the team to investigate on its behalf. Some of those numbers are for people familiar to the team, which gives them a good idea if these numbers are the targets or the perpetrators. The fifth number is one who they have to do some digging to discover the person's identity. But as they work through the process, they will find that they must get into bed with unusual bedfellows all in the name of the bigger goal.

Reese, who is tasked with finding them, quickly learns that they are the intended targets, as they stole $500,000 in drug money from the Brotherhood, a gang led by the unknown Dominic. Reese knows of the Brotherhood because he helped put in jail one of the gang's higher ups, Link, who is now out. The DEA is interested in the case, their head agent being Erica Lennox, who decides to work in conjunction with Reese as she knows there is a mole in the DEA working for the Brotherhood. When Reese and Lennox eventually find Malcolm and Tracie, they learn the reason why they stole the money. However, Malcolm has hidden the money and refuses to give it back. Reese and Lennox have to try and protect Malcolm and Tracie from the Brotherhood, all the while trying to get them to give up the money wherever Malcolm has it hidden, and discover the identity of the DEA mole. Shaw may be able to assist as she has one of the injured Brotherhood members, Mini, in unofficial custody; he who may buckle under the pressure of being in the gang.
