In 1991, years prior to the events of NCIS, Leroy Jethro Gibbs 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 NCIS legend Mike Franks.
The team investigates the brutal murder of a veteran who fell on hard times after serving in Vietnam, leading Franks to reflect on his own struggles following the war. Also, Gibbs considers a new path forward.
