NCIS: Hawai’i is the third successful spin-off of the NCIS series from CBS, and there is plenty of NCIS: Hawai’i season 3 news despite the new season facing delays. NCIS debuted in 2003 as a spin-off of the military legal drama JAG. While JAG placed much of its drama in a courtroom, NCIS focuses on the investigation instead. Though NCIS takes place in Washington, DC, each of the spin-offs has taken place in a different location. NCIS: Hawai’i marks the first one outside the contiguous United States.
