'NCIS': Everything We Know About The Anniversary Episode
NCIS will soon enter its 18th season and celebrate episode number 400. For nearly two decades, the series has delighted fans with engaging criminal cases. Now, we're learning first details about the new season of police drama and the special 400th episode of NCIS.
For starters. The first two episodes of NCIS season 18 were intended for the previous season, which ended prematurely due to the COVID-19 crisis. The season 17 finale also would have been the 400th episode of the series.
So, ahead of the new season, there are big plans for episode 400. Speaking to TV Insider, show executive producer Frank Cardea, 73, revealed the milestone hour-long episode will focus on special agent "Leroy Jethro Gibbs" (Mark Harmon) and his long-time friend, the coroner "Dr. Donald 'Ducky' Mallard" (David McCallum).

"It's a very special episode," Cardea said of NCIS 400. "It's about Gibbs and Ducky and how they met. A case brings them back to 20 years earlier."
With the episode exploring "Gibbs'" past, Mark Harmon's son Sean Harmon, 32, returns to play the younger version of the NCIS agent. "The goal for this episode was to write a love letter to the longtime fans," the NCIS executive producer added.
