NCIS (Naval Criminal Investigative Service) is more than just 
an action drama. 
With liberal doses of humor, 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. 
Leroy Jethro Gibbs, a former Marine gunnery sergeant, whose 
skills as an investigator are unmatched, leads this troupe of 
colorful personalities. 
Rounding out the team are Anthony DiNozzo, an ex-homicide 
detective whose instincts in the field are unparalleled and whose 
quick wit and humorous take on life make him a team favorite; 
the youthful and energetic forensic specialist Abby Sciuto, a 
talented scientist whose sharp mind matches her Goth style and 
eclectic tastes; Caitlin Todd, an ex-Secret Service Agent; and 
Timothy McGee, an MIT graduate whose brilliance with computers 
far overshadows his insecurities in the field. 
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. 
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
