From Donald P. Bellisario comes NCIS, a show bringing us the inner workings of the government agency that investigates all crimes involving Navy and Marine Corps personnel, regardless of rank or position. 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. Leading this team that operates outside of the military chain of command is Special Agent Leroy Jethro Gibbs (Mark Harmon), a skilled investigator and interrogator who is smart, tough and willing to bend the rules to get the job done.
