While recovering after heart surgery at the Naval Medical Center, Bethesda, Maryland, a commander dies due to an internal flash and the resulting fire without any apparent external source of ignition; Gibbs and company investigate. McGee suggests the possibility of spontaneous human combustion (SHC), Gibbs makes fun of it, Ducky declines to ignore it, and Abby digs it. However, Abby says that it's murder. Tony sees again a friend from Gitmo, then a party in a hotel room leads to a missing officer at a swimming pool. Ducky wines and dines the woman surgeon, but he later becomes disappointed in her. Abby finds a key fact, then the team solves the mystery.
