When a marine captain shows up at Camp Pendleton exhibiting symptoms of a fatal virus, NIS goes on lockdown and Gibbs is forced to take charge. As panic spreads, the team races to determine whether it really is a deadly outbreak or something else entirely.
NCIS: Origins is set in 1991, years prior to the events of NCIS. The new series will follow a young Gibbs as he starts his career as a newly minted special agent at the fledgling NCIS Camp Pendleton office, where he forges his place on a gritty, ragtag team led by legend Mike Franks.
