The guide’s photo captions identify Alden Parker, Leon Vance, Timothy McGee, Jessica Knight and Nick Torres in the episode’s team lineup. It does not publish a detailed scene-by-scene synopsis, so the family connection to Gibbs and the emergency call are the key confirmed story details.

When did “All Good Things” air?
The original CBS broadcast was Tuesday, March 24, 2026, at 8 p.m. ET/PT. That date and time come from the official Paramount+ episode guide, so listings that describe the milestone as airing “tonight” are using an outdated schedule reference rather than describing a September 30 broadcast.
How to watch the 500th episode
The official guide lists CBS and Paramount+ access, with timing dependent on the viewing method. Subscription names, regional availability and catalog placement can change, so check Paramount+ and local CBS listings before watching.

| CBS | Original broadcast | Tuesday, March 24, 2026, at 8 p.m. ET/PT. |
| Paramount+ Premium | Live as CBS aired it | The Premium plan could stream the episode live alongside the CBS broadcast. |
| Paramount+ any plan | On demand the next day | The episode became available on demand the day after broadcast with any Paramount+ plan, according to the guide. |

What the milestone means for viewers
Episode 500 is a franchise production milestone, but the episode’s confirmed hook is character-driven rather than a standalone retrospective: Gibbs’s past help to a Marine’s son becomes the reason the current team must respond. That setup connects the show’s history to the Parker-led team named in the official guide.
