It is later revealed the stalker is using Tyler's home to get their hands on four million dollars in stolen Iraqi aid money. "Requiem" was originally intended to be the 100th episode of the series, until the producers switched the order with "Chimera" because they believed it would be suitable to air near Halloween.

Plot The episode begins with Special Agent Anthony DiNozzo (Michael Weatherly) shooting two armed suspects at a dock before diving into the water to save his superior Leroy Jethro Gibbs (Mark Harmon) and a young woman from a submerged car. DiNozzo then attempts to resuscitate them. The narrative focuses twenty-four hours earlier. The young woman, Maddie Tyler (Cameron Goodman), arrives at NCIS to see Gibbs. Tyler was the childhood best friend of Gibbs' daughter Kelly. Her father, a retired Marine, has died and she has no one but Gibbs to advise her about a personal issue. She asks for his help regarding her Marine ex-boyfriend Rudi Haas (Nick Spano), whom she believes is stalking her. At her apartment, Gibbs confronts Haas and warns him to stay away. After returning to NCIS he, DiNozzo, Timothy McGee (Sean Murray) and Mossad liaison officer Ziva David (Cote de Pablo) initiate an investigation on Haas. Tyler later calls Gibbs to tell him Haas has returned. By the time Gibbs arrives, he finds her home ransacked and witnesses Tyler being forced into a Jeep. Tracing the Jeep to an abandoned factory, they also find Haas dead. Following an autopsy, Medical Examiner Donald Mallard (David McCallum) confirms that Haas was murdered sometime before Tyler's kidnapping, meaning somebody else took her. It is revealed that Haas was under investigation after he and two other Iraq War veterans were suspected of stealing four million dollars of aid
