Loglines for the "NCIS Day" mini-marathon episodes, airing Monday, Sept. 25 on CBS and available to stream on Paramount+*, follow:

8:00-9:00 PM, ET/PT

NCIS Season One Premiere Episode (OAD: 9/23/2003)

"Yankee White" - In the series' premiere episode, NCIS (Naval Criminal Investigative Service) Special Agents Gibbs (Mark Harmon) and Tony DiNozzo (Michael Weatherly) and NCIS medical examiner Dr. "Ducky" Mallard (David McCallum) arrive on Air Force One to investigate what initially appears to be a death by natural causes. But their investigation is hampered by inter-agency squabbles with the FBI and Secret Service, each believing that they should be the primary investigating unit. Gibbs cunningly gets control of the case from the others, but still has to go head-to-head with Secret Service Agent Kate Todd (Sasha Alexander)*, who insists she remain on the case. As the investigation continues, the sudden death of another Marine officer with the same job as the first victim convinces Gibbs and Todd that they are dealing with a terrorist plot against the president - and the killer is getting closer. (*Alexander was a series regular in this series premiere episode of NCIS, becoming an NCIS special agent by the episode's end.) Executive producer Donald P. Bellisario both directed the episode and wrote the script.

9:00-10:00 PM, ET/PT

NCIS Second Season Finale Episode (OAD: 5/10/2005)

"SWAK" - When a letter sealed with a kiss is delivered to NCIS, Tony (Michael Weatherly) assumes it's for him and opens it, only to release a mysterious powder into the NCIS squad room. Gibbs (Mark Harmon) and the team are forced into quarantine in the NCIS autopsy room pending the results of tests to identify the strange powder. As Abby (Pauley Perrette) discovers the substance is a genetically altered version of the plague, Tony and Kate (Sasha Alexander) are placed in a bio-hazard isolation ward for fear of exposure. In the clear of the deadly virus, Gibbs and McGee (Sean Murray) race to track down the sender before the deadly plague destroys one of their team members. Steven Eckholdt guest stars as the doctor who treats the infected NCIS agent; Mariette Hartley guest stars as a potential suspect. Dennis Smith directed the episode from a script by executive producer Donald P. Bellisario.

10:00-11:00 PM, ET/PT

NCIS Season 19 Episode (OAD: 1/17/2022)

"All Hands" - After a civilian research vessel in the North Atlantic picks up a small boat of wounded Navy officers, Special Agent Parker (Gary Cole) and his NCIS team arrive on the ship and are forced to hide after discovering terrorists on board. Also, Special Agent Knight (Katrina Law) takes a paper doll with her on the mission to capture photos for her niece's grade school class. Martha Mitchell directed the episode from a script written by Christopher J. Waild.
