Brennan and Booth look into the death of a man murdered for the contents of his briefcase. The evidence leads them to suspect that a group of secret operatives were behind the murder, and their suspicions are confirmed when remains of a CIA agent are found in the trunk of a car. When Brennan and Booth question the CIA's Assistant Director of Intelligence, they question the man's allegiance to the U.S. Meanwhile, the financial success of Brennan's latest book leads to a rift between her and Booth; and when Wendell loses his scholarship, the team searches for alternate funding in order to keep their intern around.
