The murder of kidnapped teenaged twin boys leads to Bones and Hodgins becoming the next victims of the sinister, "Grave Digger". As they are trapped underground and quickly running out of oxygen, Booth leads the search for them.

Note: The case as broadcast has no conclusion (it was solved in the season 4 episode "The Hero in the Hold"). The Fox Network website initially displayed a summary for the episode which included an original ending where the Grave Digger was identified as the female reporter that coauthored a book about Grave Digger. The summary was later revised to reflect the episode as broadcast in which the Grave Digger is unidentified and the scene replaced by character reunion moments.

* HowWeGotHere

* YouKeepUsingThatWord: Inverted. Bones gets highly annoyed to have her trust, based on personal experience, that Booth will save her and Hodgins from their current predicament called 'faith'. Hodgins laughingly points out that she just gave the dictionary definition of 'faith', apparently only knowing about the religious usage.

The team investigate the murder of two kidnapped teenage twin boys. The boys were placed in a spaceship-like capsule and buried alive underground. Soon, Brennan and Hodgins find themselves victims of the "Grave Digger", and Booth frantically searches for them as they slowly run out of oxygen underground.
