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.

When an agent is gunned down, Gibbs and Tony try to locate a woman in the desert who might have answers about his murder.

When a petty officer on whom McGee based a character for his latest book is murdered, McGee must figure out who could have accessed his secret manuscript.

Gibbs and the team must take action after the director's risky solo meeting with an informant ends with a death.

The team turns to a blind photographer (John Billingsley) to use his heightened senses of hearing and smell to re-create a crime scene and track down a petty officer's killer.
