Season 6
NCIS (Naval Criminal Investigative Service) is more than just an action drama. With liberal doses of humour, it's a show that focuses on the sometimes complex and always amusing dynamics of a team forced to work together in high-stress situations.
NCIS Special Agent Leroy Jethro Gibbs, a former Marine gunnery sergeant, whose skills as an investigator are unmatched, formerly led this troupe of colourful personalities.
Gibbs, a man of few words, only needs a look to explain it all.
The team includes NCIS Special Agent Anthony DiNozzo, an ex-homicide detective who may come off as the world's oldest frat boy but whose instincts in the field are unparalleled; forensic specialist Abby Sciuto, a talented scientist whose dark wit matches her Goth style and eclectic tastes; NCIS Special Agent Timothy McGee, an MIT graduate whose brilliance with computers far overshadows his insecurities in the field; and Ziva David, a former Mossad agent who shares a bond with Gibbs over the death of his arch nemesis, Ari, the terrorist who killed former NCIS Special Agent Kate Todd.
Assisting the team is medical examiner Dr. Donald "Ducky" Mallard, who knows it all because he's seen it all, and he's not afraid to let you know.
Rounding out the team is NCIS director Jennifer Shepard, who has a romantic history with Gibbs.
As NCIS is a federal law enforcement agency with jurisdiction on crimes involving persons and property associated with the U.S. Navy and the U.S. Marine Corps, the team is frequently assigned to high-profile cases such as the death of the President's nuclear missile 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.
From murder and espionage to terrorism and stolen submarines, these special agents travel the globe to investigate all crimes with Navy or Marine Corps ties.
Season 6 sees NCIS leader Agent Gibbs take up the task of finding a mole within his team and the introduction of the Los Angeles branch of NCIS, which was later given a spin-off series of its own (NCIS: Los Angeles).
