Radio listeners report gunshots during a live talk show; the Virginia State Police responds and finds three bodies, including that of the guest speaker, who was a Navy commander; Gibbs and company investigate; they believe that the host was the primary target; Tony finds a tape with a reference about the motive of the shooter. The widow of the host provides a carton of clues, which enable the gang to meet a mailman and a bunch of sociable suburbanites in a gated community. Ziva poses as a potential seller, and money starts moving, then a neighbor sustains an injury. The neighbor's daughter lends a hand, then the father does, then the gang collar the bad guy, find the bomb, and prevent casualties; Ziva winds up on top of Tony, who says that he had missed the old Ziva. Finally, Gibbs and Ziva play catch under the lights.
