Production has yet to begin on NCIS Season 18, but due to coronavirus shutdowns postponing at least one previously announced episode, we do have some idea of what’s in store this fall.

When the CBS procedural returns, it will be celebrating quite the milestone (the 400th episode) and going back in time to the beginning of one of boss Leroy Jethro Gibbs’ (Mark Harmon) key relationships. Plus, it’ll be time to reexamine a case from a couple years back.

Scroll down for more on what you will and won’t see when Season 18 begins.

An Unsolved Mystery

The daughter of Gibbs’ old friend Fornell (Joe Spano) nearly died after OD’ing on counterfeit opioids. The Canadian supplier was never found, but it’s been hinted that Gibbs is still secretly on the hunt. The case comes to the forefront in Season 18.

The man has opened up to his team, yes, but don’t expect Gibbs at happy hour. “The team matters,” Harmon acknowledges, but “leadership often isn’t popular.”
