TV show description:      
In this spin-off of JAG, the Naval Criminal Investigative Service (NCIS) investigates crimes to people or property affiliated with the U.S. Marine Corp. or U.S. Navy.

Major Case Response Team Supervisor (MCRT) for the NCIS, Leroy Jethro Gibbs (Mark Harmon), demands the very best from his team. They include immature, ex-homicide detective Anthony Dinozzo (Michael Weatherly); ex-Secret Service agent Caitlin “Kate” Todd (Sasha Alexander); Goth forensic specialist Abby Sciuto (Pauley Perrette); MIT graduate Timothy McGee (Sean Murray); and medical examiner Dr. “Ducky” Mallard (David McCallum). Cases investigated include an Air Force commander dying on Air force One, a Navy lieutenant gone missing, and bodies appearing at a Naval base. But no case hits as close to home as when team member Kate is killed by a terrorist. In their grief, the team bands together, with the help of Mossad Ziva David (Cote de Pablo), to avenge her death. Ziva then joins the unit in Kate’s place.

When NCIS Director Thomas Morrow (Alan Dale) leaves his position for Homeland Security, Jenny Shepard (Lauren Holly) takes his place. This proves to be a distraction for Gibbs as the two have a personal history. Later on, Leon Vance (Rocky Carroll) becomes the NCIS Director.
