The team includes NCIS Special Agent Timothy McGee (Murray), an MIT graduate with a knack for computers who is now a Senior Field Agent; NCIS Special Agent Nicholas “Nick” Torres (Valderrama), who frequently goes undercover; and NCIS Special Agent Jessica Knight (Law), a formidable REACT agent who specializes in hostage negotiations high-risk operations. Assisting the team as the NCIS Historian is retired medical examiner Dr. Donald “Ducky” Mallard (McCallum); Ducky’s protégé, the naïve Jimmy Palmer (Dietzen), who graduated to fully licensed medical examiner; and Forensic Scientist Kasie Hines (Reasonover), Ducky’s former graduate assistant.

From murder and espionage to terrorism and stolen submarines, these special agents investigate all crimes with Navy or Marine Corps ties.
