Six months after the events of last season, Booth, Brennan, daughter Christine and the new baby are ostensibly living a dream life, a world away from the murder-filled life they left behind. But a case with close personal ties to the couple compels Brennan to become involved in the forensic analysis of the remains, and Booth mysteriously goes missing, prompting an FBI investigation into his whereabouts led by Agent Grace Miller (guest star Kim Raver), who works closely with FBI Agent James Aubrey on the case. However, tensions rise when Miller tries to investigate one of the team's own as the primary suspect. The case also brings Brennan into contact with a member of Booth's family (guest star Dilshad Vadsaria), and "squintern" Arastoo Vaziri (guest star Pej Vahdat), who has been filling in as lead forensic anthropologist during Brennan's absence, hopes the temporary position becomes permanent.

Another layer is added to the mystery of Booth's whereabouts and the state of his physical condition when the team discovers that FBI Agent Miller (guest star Kim Raver) has not been entirely truthful with the FBI and the Jeffersonian, keeping vital information from them that could lead them to Booth.
