Tony returns from sick leave a week early, just in time to rejoin the team in an investigation near Fredericksburg. A man has stopped two off-duty Naval aviators in a car and has killed them by putting three rounds from a pistol into each of them; the shooter wore a uniform and drove a car, both of the Virginia State Police. Tony finds a bomb, then it explodes; Gibbs says that someone has again tried to kill the NCIS gang. Fornell says that Ari is back in the country to kill Gibbs, who drinks coffee with Ari, who tries to kill him but fails again. The team follow a stolen radio-controlled drone, seeking to defeat it; they become involved in a gunfight, and they lose one of their members.
