Avid viewers of “NCIS” know that when their beloved agents are on the job, there’s no case that they can’t tackle. Season 14 Episode 18, titled “MIA,” centres on Leroy Jethro Gibbs (Mark Harmon), who leads his team as they re-investigate a closed case that was originally considered an accidental death.

Spoilers suggest that it’s going to be an emotional episode – the “NCIS” crew will reportedly open the probe to honour a sailor’s dying wish. They discover that contrary to the previous finding, the victim did not die accidentally but was actually murdered. Gibbs, along with his team, may be reminded that this is what their job is all about: bringing forth justice.

Gibbs joins other “NCIS” characters who will also be featured on the March 14 episode, including Alexandra “Alex” Quinn’s (Jennifer Esposito), Timothy McGee (Sean Murray), Eleanor Bishop (Emily Wickersham), Jimmy Palmer (Brian Dietzen), Abby Sciuto (Pauley Perrette), Leon Vance (Rocky Carroll), Nicholas “Nick” Torres (Wilmer Valderrama), Dr Donald “Ducky” Mallard (David McCallum) and MI6 Officer Clayton Reeves (Duane Henry).

TV Guide reports that Tuesday’s installment also puts the spotlight on Torres. Fans would learn a little more about one of the new members of the team, particularly his background. “NCIS” spoilers suggest that the investigation strikes a chord with him since it brings back a tragic memory from his past. CBS posted a sneak peek of “NCIS” Season 14 Episode 18. In the trailer, Gibbs confronts Torres and wonders if there’s a problem. “You know there is,” Torres angrily says. “What are you trying to do?” Gibbs’ reply is short and sweet, as he tells him, “My job. I suggest you do yours.”

“MIA” is directed by Tom J Wright and written by Jennifer Corbett, according to the Internet Movie Database, or IMDb. “NCIS” Season 14 Episode 18 also features guest stars Katherine Cunningham, who plays Navy Lieutenant Laura Ellison and Preston Jones as Navy Petty Officer First Class David Collins.

Fans of the leading drama series should savour the upcoming episode as it goes into a brief hiatus after this week. “NCIS” will return on March 28 with an episode titled “The Wall.” Find out what happens next on “NCIS” Season 14, which airs in the US on CBS every Tuesday, 8/7c.
