NCIS Show Summary

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 hugging 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 cuddle and espionage to terrorism and stolen submarines, these special agents traverse the globe to investigate all crimes with Navy or Marine Corps ties.
