Inside a drum of hydrofluoric acid at an industrial site aboard the Naval Station, Norfolk, Virginia, two civilian workers find the decomposing body of a man, apparently a submariner, who died after a blunt instrument fractured his skull. Gibbs and his team go to Norfolk to investigate; attention concentrates on one particular submarine and a theft of identity; Gibbs and Kate continue to USS Philadelphia (SSN-690), which got underway the day before. The commanding officer and his chief of the boat give limited and begrudging cooperation due to the nature of the exercise in progress. The other members ashore help greatly; Gibbs nails a terrorist aboard and saves the crew from mass death. Written by

During a waterfront scene, ostensibly in Norfolk, in the background there's a ship bearing the hull number AE-31, which was USS Chara, a cargo ship of the Andromeda class, which served first as AKA-58 (an attack cargo ship, 1944-59), later as AE-31 (an ammunition ship, 1966-72). However, on 12 November 1972 the Navy sold the real Chara for scrap. See more
McGee identifies the blue cable as a DSL (Digital Subscriber Line) when it is just a standard Cat 5 cable. DSL doesn't require special cables, a standard phone line is all that is needed to connect the wall jack to the DSL modem. The Cat 5 cable is used to connect the modem to the computer and would then be called an EtherNet cable. See more
