While honeymooning in Buenos Aires, Brennan and Booth can't just relax on vacation. So, instead, they decide to help Raphael Valenza, a local detective and huge fan of Brennan's books, solve the murder of a Nazi war criminal whose remains were found in an historic mass grave. Meanwhile, back in Washington, D.C., Hodgins and Angela struggle to take care of Christine while Brennan and Booth are away.

Brennan is a juror on the case of professional soccer player Peter Kidman who is accused of murdering his wife. When she uses pure objectivity to help prove the killer not guilty, his best friend and a key witness in the case turns up dead. The Jeffersonian team must work together to prove that the soccer star was in fact guilty of killing both his wife and his friend.
