STAGE TUBE: Sneak Peek - A Christmas Miracle on CBS's NCIS

In tonight's episode of CBS's NCIS entitled 'Newborn King", it's Christmas Eve and before the night is over, one agent will try to deliver the biggest miracle of all. 

NCIS (Naval Criminal Investigative Service) is 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, leads this troupe of colorful 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 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; NCIS Special Agent Timothy McGee, an MIT graduate whose brilliance with computers far overshadows his insecurities in the field; and Ziva David, perhaps the most dangerous member of the team, a former Mossad agent now Probationary Agent and newly sworn-in U.S. citizen.

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 Leon Vance, an intelligent, highly trained agent who can always be counted on to shake up the status quo. 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.

NCIS airs Tuesdays at 8/7c on CBS.
