A promo during Sunday's Super Bowl might've scored big with "NCIS" fans.

An ad for the long-running CBS series spotlights former fan favorite special agent Ziva David, played by Cote de Pablo. The Chilean-American actress was written out of the show in 2013 when she decided to leave after an eight-year run.

"You thought her story was over, now the biggest 'NCIS' secret of all will be revealed," the promo promises of its episode airing Feb. 12.

Fans thought Ziva's story was over because the character, a former Mossad agent, was killed offscreen when the Israeli farm where she was staying was fire-bombed during the Season 13 finale. It was then that fellow agent Anthony DiNozzo (Michael Weatherly) learned she left a child behind and he was the father. At the end of the episode, he decided to leave NCIS to care of her.

Now, a release for the episode on CBS' press site offers insight to Ziva's resurfacing. "After a malnourished and confused 9-year-old is found hiding in a storage unit, NCIS reopens an old missing persons case when the girl is believed to be the daughter of a Navy recruit who disappeared 10 years ago," states the release. "Also, (Ellie) Bishop discovers notes that Special Agent Ziva David kept on the case long after NCIS officially stopped investigating."
