NCIS is the abbreviation of Naval Criminal Investigative Service, which literally means Naval Crime Investigation Service. This special department under the Pentagon specializes in investigating any crime related to the Navy and the Marine Corps. The Naval Investigation Service is given special investigative powers. As long as the case requires, everyone must be questioned regardless of their position and rank. The NCIS team encounters a variety of different cases every time, from murder, drug enforcement, espionage, to anti-terrorism operations, and even mysterious religions. At the end of last season, Ziva's red and swollen eyes shocked all the audience. What happened to Ziva, who has suffered so much, and will she return to the NCIS family? Is Tiva going to end before it even begins? Can McAbby develop? And what is the mystery of the boss's ship? All the mysteries will be revealed to you in the seventh season.
