Gabrielle receives a package containing documents relating to the assassination of President John F. Kennedy from a certain source in Pennsylvania, who was killed within the hour of sending the package. She brings the entire package to Alexander in hopes of convincing him that it is worth a two-week fishing expedition in Pennsylvania. A certain US government official tracks that package to Gabrielle and orders her home to be ransacked. Two men ransacks her home just as she gets back from the meeting with Alexander. During the ensuing struggle, Sinclair and Stone arrive to tell her that Alexander has denied her request, instead find themselves coming to rescue Gabrielle from her attackers. After that incident, Alexander believes that the ransacking of Gabrielle's home is directly related to the pacakge she received earlier and send the team to Pennsylvania to investigate, and if possible clean up, this historic mystery.
