In a division of NCIS that is charged with apprehending dangerous and elusive criminals that pose a threat to the nation's security, this team of highly trained agents put their lives on the line in the field to bring down their targets.  When a Navy counselor paying a home visit to a former Navy SEAL finds him inside his house, tortured and murdered, NCIS is called in to investigate. Meanwhile, a bank hold-up goes bad downtown and an LAPD officer is shot. The cop is a friend of Deeks', but a trace on the getaway vehicle shows no connection between the crimes--until NCIS digs deeper.
