The Virginia State Police calls the NCIS to a shooting of a Navy petty officer first-class; Gibbs and company find the murder weapon at the scene; Abby traces the piece to a pawnshop in Maryland, then Gibbs and Tony trace it to Kim, a young woman. While at the shop Tony sees a Medal of Honor and asks about it; Leroy Jethro Moore had received it for valor during World War II; Gibbs recognizes the name of his father's former best friend, for whom Jackson had named his son. Kim says that she gave the pistol to Kris, her brother, who says that someone stole it from the trunk of his car, and who later identifies a motorcycle and a rider. The team find the pieces and put them together, then with help from a billionaire and $1M, they find the shooter, to whom the whole gang plus a couple of friends give a good-morning hello. Gibbs helps his father and his old friend to overcome an old difficulty. Meanwhile Abby declines an interesting dinner date.
