Maffia will play Vera Strickland, an experienced, tough Special Agent who is on the cusp of retirement. And there's a good chance she'll share some history with Gibbs (Mark Harmon).
"Roma Maffia is a wonderful actress who fits this role perfectly," executive producer Gary Glasberg tells TVGuide.com. "Considered 'one of the boys,' her character goes all the way back to NIS and Mike Franks [guest star Muse Watson]. We couldn't be happier to have Roma for this very fun episode."
Besides her role as anesthesiologist Dr. Liz Cruz on Nip/Tuck, Maffia has also recently appeared on such shows as Pretty Little Liars and Grey's Anatomy.
NCIS premieres Tuesday, Sept. 24 at 8/7c on CBS. Maffia's episode is slated to air in October.
