When the Jeffersonian team investigates the death of a former Marine sergeant whose remains were found burned to a crisp, they discover that she was discharged after a fist fight with another Marine. When Booth and Sweets go to question the other Marine involved in the altercation, they learn that Deanna was obsessed with the idea of the apocalypse, which leads the team to a following of doomsday preppers who become key suspects in her death.
