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
During one scene while operating submerged, the conning officer gives the order "250 feet", and shortly afterward the chief of the watch gives the report "250 feet and passing". The order "250 feet" requires the chief of the watch to reach the depth of 250 feet and maintain it, not pass that depth and continue going. See more
