At the beginning of the story, the agency finds itself under attack from an unknown enemy. As the NCIS agents work to uncover the identity, viewers are treated to “a lot of heavy nods to that [first episode], a lot of characters that we haven’t seen and people that were in the first episode, such as Joe Spano as Fornell,” Sean Murray, who plays Timothy McGee, told Parade.
“Without giving anything away, the whole team is together trying to stop something from happening with Air Force One. We did a lot of fun things when we filmed where we put in a lot of references visually and dialogue-wise to a lot of things that the longtime fans will appreciate. Little Easter eggs hidden around the episode.”
