All episodes from the first 13 seasons of the JAG spin-off series NCIS, centering on the Naval Criminal Investigative Service, a crack team of government agents who operate outside the military chain of command. These special agents traverse the globe, investigating crimes linked to the Navy or Marine Corps - from murder and espionage, to terrorism and stolen submarines. More than just an action-packed drama, NCIS shows the sometimes complex, always amusing dynamics of a team forced to work together under high-stress situations.
