A lieutenant commander, Hill, the engineer officer aboard a boomer submarine, disappeared 28 days ago; last night his body fell from a street overpass in Los Angeles in an apparent suicide; however, Eric learns that Hill died of a cocaine overdose before he hit. Granger tells Hetty that she's now on an administrative leave during an investigation of the matter about the White Ghost; he says that the inquiry is a witch hunt in Washington, and she says that she holds the broom. The foursome review conflicting evidence, and the Wonder Twins produce clues; G and Sam chase a witness and chat him up; the four, acting on a clue from Eric, make a house call, where they meet a firestorm and return a hand grenade; Kensi and Talia meet each other; at a boatyard G and Sam make a major discovery; at another waterfront facility G and Sam find a distinctive vessel, board it, and get several surprises; the vessel gets underway and starts making way. [To be continued next season.]
