Reese and Finch are confused when the Machine produces four numbers. When Reese finds one person of interest dead and is unable to prevent the murder of a second, he realizes that all four have something in common, and begins to dig deeper. He finds that the four stole drug money from the scene of a car accident, and that a corrupt banker and congressman are conspiring to have them killed for it. Meanwhile, Detective Carter has been stood down following the death of her confidential informant in "Get Carter". She is approached by a man named Snow, who identifies himself as a CIA operative, and asks her to lead him to Reese, revealing the reason why Reese faked his death - Reese was responsible for the death of his CIA handler, Cara Stanton, and then disappeared, until Carter's investigation put him back on the agency's radar. Finch confronts the conspirators and records evidence that they established a charity in Haiti to launder drug money. Reese saves the two women by killing their attackers. But before he can escape, he is shot by a CIA assassin. Carter finally catches up with him, but decides to let him escape.
