Torres must rely on old case notes and contacts after a Marine's murder is linked to a former dirt bike gang he joined for a year-long undercover operation.
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.
