Reese and Finch receive the number for Wallace Negel -- a mysterious man who hasn't had a single electronic transaction in his name since 1989. But as they dig for more details, they begin to suspect that Negel is not who he seems. Reese knows a cover identity when he sees one. This man is a spy. When bodies start to turn up, Reese and Finch need to figure out how they are connected to this agent and why he has returned to New York City after so much time. In this game of spy vs. spy, the old school operator matches his spycraft against Reese and Finch's neo-technology. We also learn more about Reese's early days in the CIA and his relationship to a mysterious woman named Stanton.

­The machine gives Finch 4 numbers almost simultaneously, which means the POI's are probably connected. When they find the first number murdered, Reese enlists Finch and Fusco to help keep the others safe. Unfortunately Finch isn't able to get there in time for the second victim. Reese figures out that the remaining two numbers are foster sisters and manages to rescue them from an attempt on their life. Finch determines that all four seemingly unconnected people met at the scene of a car accident and they did something to make them targets.
