In a series of flashbacks to Shaw's childhood it is revealed she was in a car with her father when he was killed in a wreck, but that she showed a lack of emotion over it. In the present, Shaw saves another number. The team's next number turns out to be a Russian immigrant girl named Genrika Zhirova (Danielle Kotch), who is deeply interested in espionage and is living with an older cousin in a run-down apartment. Shaw ends up watching after Genrika when men come to attack her. Genrika had been b

While Shaw is abducted by Root, Finch and Reese get the number of Timothy Sloan (Kirk Acevedo), an estate investigator. Finch goes undercover as Sloan's assistant while Reese continues investigating Shaw's whereabouts.

Finch soon learns that Greenfield used to be a member of the organization Vigilance, which includes Peter Collier (Leslie Odom, Jr.) (from the

Reese and Finch get the number of Hayden Price (Aaron Staton), a hypnotherapist. Finch, who poses as Hayden's patient, learns that Hayden is a con man who hypnotizes his patients into giving him their security information, which allows him to enter their bank accounts and steal from them. One of his patients, Sven Vanger (Carsten Norgaard), is in fact a money launderer for HR who bids fake items at auctions. One of the items he purchased is a baseball signed by the 1922 New York Yankees team, wh

Finch receives 38 numbers, all members of HR. Carter intercepts a drug delivery of the Russian mob, causing leader Peter Yogorov to suspect HR. Carter starts a war between HR and the Russians by firing sniper shots at HR leader Alonzo Quinn, who blames the Russians. Quinn orders his right-hand man, Simmons, to have his men round up the Russians. Reese learns about Carter's plan, and Finch deduces Quinn's identity as the head of HR. The Russians' numbers come up as they are now threatened by HR,

Reese and Carter are crossing town to deliver Alonzo Quinn to the FBI. Simmons alerts HR and several criminal groups of Reese's identity, limiting their means of movement. The two fight their way to, and break into, the city morgue. Simmons and Detective William Petersen (Lee Tergesen) capture and torture Fusco for the location of Carter's safe deposit box, which contains evidence against HR. To break Fusco, Simmons sends Lin (Khalil Kain) to kill his son Lee (Sean McCarthy); but Lin is killed b

Flashbacks illuminate Finch's dealing with survivor's guilt, Reese's time doing wetwork, Shaw's former life as a technically excellent surgeon but completely indifferent to the people she helped, and Fusco's recounting of exacting vigilante justice to a crook that slipped through the system (the devil's share). Reese starts sliding into his old, dark ways to get Simmons while also sliding towards death. Finch, Fusco, and Shaw go to an HR attorney to know Quinn's whereabouts to question him for S

Reese leaves the team and heads for Colorado, where his father had lived. The Machine provides a new number to Harold, who at first is reluctant, but eventually accepts it on Root's insistence. The number belongs to Arthur Claypool (Saul Rubinek), Harold's close friend during his days at MIT. Claypool has been diagnosed with a brain tumor and is being monitored at the hospital, being kept under Secret Service guard. Arthur's wife, Diane (Camryn Manheim) tells the disguised Doctor Shaw that Arthu

Control holds Harold, Shaw and Arthur captive. She orders Shaw killed, but Root enters, guns blazing, and frees the trio. Root herself is shot and captured by Control, who tortures her, demanding access to the Machine. Control destroys the hearing in Root's right ear and threatens to make her completely deaf and blind. Meanwhile, Arthur reveals that he has a copy of the Samaritan AI in a safe-deposit box. They go to retrieve it, and Vigilance militants attack the bank. Harold locks himself, Arth

Reese boards an international flight to get away from his former life, but the Machine makes changes to his itinerary causing him to take another one. Initially Reese is angry at Harold thinking he has made the changes, but Harold convinces him otherwise. It turns out that Owen Matthews (Samm Levine), a passenger on the plane is a witness being escorted by U.S. Marshals, and he is the intended target of multiple assassins including the ISA. After Reese foils several assassination attempts, Finch

The team's next case is that of Kelli Lin (Elaine Tan), a former silver medal-winning Olympic gymnast who is later revealed to be an antiquities thief long pursued by Interpol. Shaw investigates Kelli's house, learning that her next operation is to steal a Gutenberg Bible that is being shipped out that night. Shaw foils the plan but is confronted by Kelli, whose boss Cyril (Gene Farber) is an extortionist revealed to be forcing Kelli to commit robberies while her daughter is held captive. Finch

When the number of Sandra (Melissa Sagemiller), a 911 operator, comes up, Harold goes undercover at the 911 call-center. Later, a child is kidnapped and the call is routed specifically to Sandra. She is ordered to delete an earlier day's 911 call logs, in return for the child's life. Meanwhile, the case overlaps with one of the murder cases with which Fusco was helping a rookie detective. It turns out that a woman was killed by her married ex-boyfriend and boss, and the family hired a cleaner to

In 2010, Harold works with Dillinger (Neil Jackson), an ex-Blackwater mercenary who performs the same duties later performed by Reese. Their current number is Daniel Casey (Joseph Mazzello), a hacker who tests computer security systems. Multiple parties attempt to eliminate Casey, including Reese and Stanton (secretly arranged by Control) and agents of Decima Technologies. Dillinger saves Casey and brings him to Harold, who realizes Casey's last job was to find a way to access the Machine. Altho

The Machine orders Root on several tasks such as helping a convict escape and using him to impersonate a Department of Defense employee in order to obtain a secret note. Afterward, she and Harold's team coincidentally reach the same person, a janitor. It later turns out that NSA has been testing an advanced supercomputing chip and the janitor was one of the 15 people who had access to the development lab. This makes both Decima and Vigilance come after him. While Harold and his team's assignment

The team receives the number of Maria Martinez (Nazneen Contractor), an engineer working for the international energy company HydralCorp. Maria is working to clear the name of Omar Risha (Haaz Sleiman), a man from Iraq suspected of being a terrorist. Shaw, Fusco and Reese save Maria from an assassination attempt and learn that Omar was her translator in Iraq and saved her from a terrorist ambush during the shipment of six generators. The generators went missing and Omar learned about their disap

The team witness Leona Wainwright being killed by a suicide bomber. She worked for the government, managing security clearances; Finch deduces from cell phone information that Vigilance killed her. Their next number, prosecutor Matthew Reed (Nestor Carbonell), sends Reese and Shaw to a high school reunion in Westchester. They manage to prevent a planned murder, while fending off an ambush by Vigilance. Meanwhile, Finch and Fusco go to Washington, D.C. to find out why Leona was targeted, but Vigi

The new number is Congressman Roger McCourt (John Heard), who serves on the powerful Rules Committee. The team is initially baffled: He has no obvious enemies. They eventually discover a connection to Decima: McCourt admits to agreeing to help Decima with favorable legislation (granting Decima access to government surveillance feeds), in exchange for insider stock-trading tips. Reese concludes that the team is the “danger”, because the Machine wants them to kill McCourt in order to prevent futur

With Finch having disappeared, Decima initiates their plan with Samaritan, and when unable to find Finch, they look for his closest connection and the number received is that of Finch's fiancee Grace. The Machine also provides Grace's number as a result, and Reese, Shaw and Root work to protect her while evading Decima, who use Samaritan to spy on them within the range of New York. Grace is eventually kidnapped and interviewed by Greer, who reveals his extensive knowledge of her and begins askin

In a series of flashbacks to 2010, the narrative reveals the backstory on Collier, the face of Vigilance. His brother had been falsely accused of terrorist activities, held without trial, and had committed suicide as a result. The Machine's latest numbers include Control, Senator Garrison, a presidential assistant, and a seemingly unconcerned Greer. Vigilance kidnaps them, along with Finch, and the episode ends with Vigilance about to conduct a private trial of their detainees, while Reese and S

The trial continues. Reese, Hersh and Fusco search for the courtroom. Shaw helps Root smuggle seven servers into the Samaritan array. Hersh finds a bomb, wired to go off when the power comes on. Control is found guilty. To save her life, Finch confesses to building the Machine. When a command post is compromised, Collier moves the trial to the roof, where Decima attacks. Greer reveals that he himself created Vigilance. He wanted an atrocity—the bomb—to justify Samaritan. The bomb explodes, Greer
