Reese, Shaw and Finch are too late for their latest number, Leona Wainwright, as she is killed in front of Reese and Shaw's eyes. They know that Leona was killed by Vigilance for information she would have had unwittingly with regard to the Machine as a federal government employee. Finch decides to take Fusco to Washington DC to see if they can discover what information Vigilance wants, which is probably housed somewhere in Leona's physical or virtual office. Their problem is that the FBI is also involved in the investigation, which means that the Bureau has first access to all relevant information regarding the case. Root is getting her own information from the Machine as to Vigilance's involvement with Leona's death and what they will do to obtain whatever information they are looking for. Leona's death also causes nerves to rise within the politicos in the know, that nervousness which funnels its way to Control. Meanwhile, Reese and Shaw feel like they are being punished by Finch in dealing with the next number, that belonging to lawyer Matthew Reed. The punishment as they see it is that they are forced to go undercover as former high school classmates of Matthew's, he who is attending his twenty year high school reunion in Westchester for the weekend. Reese and Shaw figure that Matthew is the target as he seems unwelcome at the reunion by many, who believe he killed his girlfriend at the time, Claire Klein. After a fight with Matthew, Claire was found dead in Matthew's car on graduation night. Although there are open taunts toward Matthew regarding Claire's death, there are also subversive public ones by an unknown person, probably the perpetrator, meant to scare. The most likely candidate as the person after Matthew is Doug Hemmill, who was Claire's male BFF. Reese and Shaw's task in finding out what is going on with Matthew is made all the more difficult by masquerading as the people who have a certain and largely unknown history with those at the reunion, and by what Finch, Fusco and Root are dealing with in DC.
