In a parking garage on Rodeo Drive in Beverly Hills, California, near Los Angeles, two shoppers find the body of a man less a crudely severed hand, which is missing; the victim was a Marine corporal, stationed at Camp Pendleton and assigned as a clerk in the G2 (intelligence) office with a top-secret clearance; Vance has expressed interest, so Callen and company investigate. Nell, an enthusiastic new analyst who finishes the sentences of others, has arrived for duty. Eric and Nell see a clue about the amputation; the musketeers conduct interviews; Eric and Nell find more clues; G and Sam find a body and another severed hand; Kensi, Eric, and Nell follow a trace to a Muslim jeweler in Beverly Hills; G and Sam start toward a lunch but bump into the jeweler and some friends; Kensi and Deeks meet the jeweler's wife and find a bloody knife; Sam adds a factoid; the team seek and find the real killer and the rest of the story. Kensi arranges to make a special delivery.
