ÂWhen Naval Commander Maya Burris is found dead from a sniperâ€™s bullet, the NCIS realize the killerâ€™s aptitude for cleaning up the crime scene indicates a familiarity with police procedure. A likely suspect is her husband, Nick, a D.C. homicide detective who benefits from her death with a $400,000 life insurance policy. However, he appears devastated by the murder and Tony helps him cope by promising to bring his wifeâ€™s killer to justice. Ziva tries to avoid her boyfriend, CIA Agent Ray Cruz, after being stood up on a date, but when he later proposes to her, Ziva seriously considers marriage even while Tony seems conflicted by the news. Meanwhile, the team discovers that Maya was trying to bring down a renowned terrorist organization and she frequently met with Barry Norton, a former embassy liaison turned traitor who was selling government secrets to the terrorists. The NCIS believe that Norton killed Maya after she threatened to expose him, but things take a turn when Norton himself shows up dead and the team realizes he was the target all along â€" Maya was simply collateral damage. Tracing Nortonâ€™s cell history leads them to the actual hitman: Ray, who was sent to kill Norton as a matter of national security. Ziva is devastated and calls things off with Ray, even as his career is now ruined.
