Next Tuesday’s NCIS will feature a two-episode storyline that involves a military plane crash. The plane was carrying the caskets of fallen Marines and this will prompt Gibbs to flashback to his days as a Marine.
“There’s a huge crime scene, and an investigation takes part in trying to identify those remains — with in some cases the remains not being what they were supposed to be,” Harmon said. “The case kind of births with that, and forces Gibbs to remember a couple of things from his past that connect him toward this current [mystery].”
