While the NCIS team investigates the cause of a hit and run accident that resulted in the death of a Petty Officer, Gibbs searches for a way to clear a Navy Hospital Corpsman, who has served two medical tours in Afghanistan, after she's indicted for illegally providing medical aid to the victims of the crash, even though the surviving victims swear by her life-saving techniques.
Leading this team that operates outside of the military chain of command is NCIS Special Agent Leroy Jethro Gibbs, a skilled investigator and interrogator who is smart, tough and willing to bend the rules to get the job done.
Working under Gibbs is Agent Anthony Dinozzo, a former homicide detective who joined NCIS just a few years ago, but who has instincts that can come only from working on the streets.
Joining them is Agent Abby Sciuto, a gifted forensic scientist whose dark wit matches her goth-style hair and clothes, and Dr. Donald "Ducky" Mallard, a medical examiner.
From murder and espionage to terrorism and stolen submarines, these special agents traverse the globe to investigate all crimes with Navy or Marine Corps ties.
