Pam Dawber — the real-life wife of series star Mark Harmon — guest stars as an investigative journalist named Marcie Warren in the new episode "Gut Punch," in which NCIS Director Leon Vance (Rocky Carroll, who also directed this episode) assigns McGee, Torres and Bishop (Sean Murray, Wilmer Valderrama, Emily Wickersham) to COVID compliance duty at a foreign affairs summit. The assignment proves fortuitous, since the NCIS trio discovers a link to another team's murder case.
