In 2012, Mr. Reese goes undercover as an armored car security guard to prevent a robbery. In 2010, CIA plan to eliminate two of their best agents.
With some hesitancy, Carter re-enters life with Reese and Finch, in part because she feels her police work may be in jeopardy since she doesn't know who in the force she can trust, with Fusco at the top of that list. Reese believes that it still is not the time to tell either Carter or Fusco of their relationships. Regardless, Carter is in place for work on the next number, that belonging to armored car security guard Tommy Clay, who they believe is the intended victim. Reese's belief of Tommy being victim is strengthened by seeing, while Reese works under him on the three person team, that the team is ill prepared if an attack was to happen on their vehicle. Reese is only half right. He and Finch will have to uncover Tommy's hidden relationships to find out who was responsible for the hit, which works its way back to Carter and Fusco's continuing problems. Meanwhile, flashbacks show Reese on his last job in 2010 with the CIA, which explain why Snow is so eager to find Reese now.
- In 2010, Reese is listening to a message from his ex, Jessica (Susan Misner). She is upset and says she feels all alone. She says she'll wait for him.
In present day Carter talks to Reese about whether or not she can trust her friends on the force. She wants know more about the cases they're working and he offers her the chance to work the next one with them.

HR higher-up NYPD Captain Lynch (Michael Mulheren) is interrogating a man who owes them money. He wants Fusco to go with the man to pick up the money.
Finch calls Reese to say there is a new number. Since Carter clearly doesn't trust Fusco, Reese wonders if they should tell her he's working with HR on their behalf. Reese thinks it'll be safer for both of them if she doesn't know. The next number is Tommy Clay (Pablo Schreiber), who works for Grayling Armored Services in the most dangerous position for making cash pick-ups, the hopper. Reese is being planted as a trainee with the company. Reese places a camera on the truck.
Back in 2010 Reese is being assigned to a mission in China. He wants time to take care of Jessica, but they have an important mission coming up.

Reese is told by Snow (Michael Kelly) he needs to kill his partner, Cara Stanton (Annie Parisse), after the pick-up. If he does that, he'll get all the leave he needs.

Tommy and Ashley are partners. At some point Reese figures out that Tommy is both perp and victim. Ashley promptly shoots Tommy in the back, but can't bring herself to kill Reese. On her way out she's killed by Fusco and Lynch. When Lynch is about to kill Reese, Fusco shoots him with Ashley's gun.
Back in 2010 after she "paints" their pick-up area with cyalumes, Stanton then turns on Reese with her gun drawn; Snow had given her the same instruction he had given Reese! She tells him the agency wants everybody associated to the mission to be killed.
Instead of picking them us, the agency's "rescue" aircraft uses the cyalumes as a target indicator. Reese escapes just seconds before the "friendly aerial attack" kills his partner.
Back in the present, Snow and his team, entering an apartment with guns drawn in search of Reese, are ambushed and gunned down by what looks to be Stanton, Reese's late CIA partner.
