Two cyclists find a body; the victim was a woman lieutenant commander assigned to the Navy Office of Legislative Affairs; Gibbs and company investigate. Ducky says that she died elsewhere from a single shot to the back. Gibbs, in response to a phone call, meets an old friend, who's a senator, who says that he was in an affair with the victim; McGee, acting on a tip, takes a tumble and finds a revolver. A computer-generated voice taunts the director, and Gibbs introduces the senator and the director to each other. Abby solves another malfeasance. Gibbs and Tony find a second body, with a printed suicide note; however, the team figure out what really happened, and they arrest the bad people.
