When the remains of a woman from a wealthy family are found in a national park, the team thinks she may be a victim of the Ghost Killer; Booth's career might be in for some changes.

The team investigates the death of a man who had offered Booth information on a possible government cover-up related to a previous case, but was killed before their meeting took place. As Booth and the Jeffersonian team dig deeper into the burgeoning conspiracy surrounding the man’s death, it’s evident Booth may be in over his head, and his future with the FBI is put in question.

Brennan and the team attempt to absolve Booth and get him released from prison. The remains of a man who has been dead for over sixteen years prove to be significant.

Aubrey works alongside the team to investigate a government conspiracy. DNA found on a previous victim helps the team to narrow down the suspects.
