‘NCIS: Origins’ Season 3 Episode 4 Release Date, Time, Where to Watch and Preview

The prequel series ‘NCIS: Origins’ has settled into a steady weekly routine on CBS, and the next chapter arrives under the title “Ahead By a Century.” The fourth episode follows on October 27, after a season that began on October 6 on CBS and Paramount+. For viewers planning their Tuesday nights, the key details are now clear enough to lay out in full.

This guide covers the ‘NCIS: Origins’ release date, air time and streaming options for the upcoming episode, along with what the season has set up so far. The season is expected to run ten episodes, and Mark Harmon is appearing in every one of them. That gives each weekly installment added significance.

‘NCIS: Origins’ Release Date for the Fourth Episode

“Ahead By a Century” is scheduled for October 27, and it follows “Return of the Mack,” which arrives on October 20. The episode after it, “Shimmy Shimmy Ya,” is due the following week. Viewers who want to stay current therefore have only a short wait between chapters.

The season opened on October 6 with “Don’t You Forget About Me,” and “My Own Worst Enemy” followed on October 13. That places “Ahead By a Century” in the fourth week of the run. By this point the season has moved past its opening stretch and into a regular weekly pattern.

The run is also shorter than in previous years. The second season consisted of eighteen episodes, while the new season is made up of ten. With fewer hours to fill, each installment carries more weight in the larger story.

Air Time and Weekly Schedule on CBS

New episodes air weekly on Tuesdays at 10 p.m. ET/PT. That means the fourth episode should land at the same hour as the earlier chapters. Viewers outside those time zones will want to convert the start time to their own local clock.

CBS is continuing a Tuesday night lineup built entirely around NCIS programming. That context places the prequel inside a night designed for franchise viewers. It also keeps the series in a familiar slot for audiences who followed it through earlier seasons.

The weekly format shapes how the story is experienced. Audiences follow the mystery as it develops rather than receiving all ten episodes at once. There is no binge window for the new season, so each Tuesday carries its own share of discussion.

Where to Watch the Latest Episodes

The new season can be watched on CBS and Paramount+. Viewers with a standard cable or antenna setup can tune in live on the network. Those who prefer streaming can find episodes on the Paramount+ platform.

Newcomers have an easy way in. The first two seasons are available to binge on Paramount+, and watching the original NCIS beforehand is not required. Every season of the prequel is available to stream there with a subscription.

For anyone not yet subscribed, there are a few practical details. A Paramount+ free trial allows viewers to watch the new season online without paying upfront. The service works on supported phones, tablets, computers, smart TVs and streaming devices.

What to Expect From the Episode Preview

A detailed synopsis for “Ahead By a Century” had not surfaced in the listings available at the time of writing, so the best guide is the setup the season has already established. Harmon is expanding beyond his usual narrator role and appearing on screen as Gibbs in every episode. That makes the older Gibbs a constant presence rather than an occasional voice.

The most recent confirmed plot description points to where the season has been heading. The preceding episode sends Ducky and the team to investigate a young Marine found on a beach with unusual markings, while the present day Gibbs reunites with someone familiar from his past. Harmon appears throughout the season as part of a present day mystery.

The season also carries forward threads from the previous finale. That finale ended with a first kiss between Gibbs and Lala, along with the kidnapping of Randy by unknown forces. The returning core includes Austin Stowell as Gibbs, Kyle Schmid as Franks, Mariel Molino as Lala and Caleb Foote as Randy. With a young Gibbs and an older Gibbs now sharing the same season, what would you most like “Ahead By a Century” to reveal about the present day mystery in ‘NCIS: Origins’?
