A murder investigation reveals a plot to kidnap a wealthy businessman's daughter; FBI Agent Harris (Dylan Walsh) helps Castle and Beckett investigate.

Brennan and Booth investigate the body of a man murdered for the undisclosed contents of a briefcase; early evidence leads the team to suspect secret operatives are at work, and their theories are supported when the liquefied remains of a CIA agent are discovered in the trunk of a car; meanwhile, Brennan's best-selling book leads to financial success, and serves as a point of contention with Booth; and Jeffersonian intern Wendell loses his scholarship.

Booth’s detective friend, Ken Nakamura, calls him from Tokyo in a panic when his sister Sachi goes missing in Washington. Booth and Brennan are on the case, and their investigation leads them to a canal where they find Sachi’s decapitated head. Booth and Brennan meet up with Ken and trace his sister’s life away from home, and their investigation leads them to an elite escort service. When they discover that her roommate is also missing, they must race against the clock to find Sachi’s killer.
