When a key witness in Danny's case is killed just before testifying, Erin angers Danny by enlisting Anthony (Steve Schrippa) to help him find the killer. Also, Robert Lewis (Michael Imperioli) tries to force Frank to publicly support the Attorney General’s investigation of the use of excessive force by police, and Eddie and Jamie get the call for an attempted suicide.

The number comes up for an Internet data broker in the business of eliminating people's privacy, but finds his own being rapidly stripped away. Reese tries to protect him as his life is being dismantled by an unknown assailant and spiraling out of control, while Finch calls on Shaw, Carter and Fusco for help in finding whoever is after him. Meanwhile, the demoted and uniformed Carter finds herself unexpectedly paired with her new rookie partner, Mike Laskey (guest star Brian Wiles).

When Shaw is tasked to stay close to a 10-year-old (guest star Danielle Kotch) identified by The Machine, she grudgingly develops respect for the young girl's skills in surveillance and realizes it could be the very reason why the girl's number has come up. Meanwhile, Carter's mission to bring the criminal organization HR to justice risks exposure.

Freed from her psych ward confinement, Root receives a directive from The Machine that requires Shaw's assistance – by any means necessary – and takes extreme measures to gain her compliance. Also, Reese and Finch look for clues as to why a mild-mannered estate investigator’s number has come up. Kirk Acevedo (Fringe) guest stars as Timothy Sloan.

The Machine issues the number of a prominent New York lawyer whose husband was recently murdered, and the team has to quickly determine whether she orchestrated the death, or if she is being framed. Meanwhile, Carter faces an issue with her new partner, Mike Laskey, after he spots her with Reese aka "The Man in the Suit."
