NCIS is a television show that follows a fictional team of Naval Criminal Investigative Service Major Case Response Team (MCRT) special agents, headquartered at the Washington Navy Yard in Washington, D.C. It is described by the actors and producers (on special features on DVD releases in the USA) as being distinguished by its comedy elements, ensemble acting and character-driven plots. NCIS is the primary law enforcement and counter-intelligence arm of the United States Department of the Navy, which includes the United States Marine Corps. NCIS investigates all major criminal offenses (felonies), those crimes punishable under the Uniform Code of Military Justice by confinement of more than one year, within the Department of the Navy. This can be seen when the ?NCIS team? is frequently assigned to high-profile cases such as the death of the President's military aide, a bomb situation on a U.S. Navy warship, the death of a celebrity on a reality show set on a USMC base, terrorist threats, and kidnappings.
