Naval Criminal Investigative Service Special Agent Leroy Jethro Gibbs leads a group of colorful personalities in investigating crimes -- ranging from murder and espionage to terrorism -- that have evidence connected to Navy and Marine Corps personnel. The team includes MIT graduate Timothy McGee, Ellie Bishop, who specializes in international threat assessment, charismatic and unpredictable Nick Torres, and forensic psychologist Jack Sloane. Dr. Donald "Ducky" Mallard brings his vast experience in forensics into play to help solve cases.

McGee's personal life and professional life intersect when a dad from his children's school is linked to a break-in at a government storage bunker.

Dr. Cyril Taft finds key evidence when he is assigned to surgical duty for a suspect.

When a dead body is found at an ancient burial site that is thought to be cursed, the team tries to determine the motive and the symbolism behind the crime; as Torres continues therapy with Dr. Grace, he discovers that their lives are in danger.

Personal plans are interrupted when errors are found in what seemed to be a straight-forward, closed case; McGee and Delilah argue whether work should be discussed during dinner.
