Reacher Season 4 is moving into its weekly release phase after Prime Video launched the new season with three episodes at once. For fans following Alan Ritchson’s Jack Reacher, the next major date is August 19, when Episode 4, titled “Karambits and Pieces,” is scheduled to arrive.
The fourth season consists of eight episodes and begins with a three-episode premiere on August 12, 2026. After that opening batch, Prime Video is following a weekly release pattern through the season finale in September.
When will ‘Reacher’ Season 4 Episode 4 release?
Reacher Season 4 Episode 4, “Karambits and Pieces,” is scheduled to premiere on Wednesday, August 19, 2026, on Prime Video.
For viewers in the United States, Prime Video’s standard release window for many original series is 12:00 a.m. Pacific Time / 3:00 a.m. Eastern Time. Viewers in other regions should check their local Prime Video listing because availability can vary by market.
The August 19 episode will be the first individual episode released after the three-episode opening batch.
‘Reacher’ Season 4 release schedule
The season has eight episodes in total. Following the August 12 premiere of the first three episodes, the remaining episodes are scheduled to arrive weekly.
| Episode | Title | Release Date |
|---|---|---|
| Episodes 1–3 | — | August 12, 2026 |
| Episode 4 | “Karambits and Pieces” | August 19, 2026 |
| Episode 5 | “Bridge” | August 26, 2026 |
| Episode 6 | “Plum Out of Luck” | September 2, 2026 |
| Episode 7 | “Vote for Sampson” | September 9, 2026 |
| Episode 8 | “Cut” | September 16, 2026 |
The schedule gives the fourth season a relatively compact run, with the finale arriving about five weeks after the three-episode premiere.
What is ‘Reacher’ Season 4 about?
Season 4 adapts material from Lee Child’s Gone Tomorrow, the 13th novel in the Jack Reacher book series.
The television adaptation follows Reacher as he becomes involved in a dangerous investigation after a subway incident. The case grows beyond what initially appears to be a straightforward mystery, eventually drawing him into a much larger conspiracy.
The new season also changes the show’s setting. While Gone Tomorrow is set primarily in New York, the television adaptation uses Philadelphia as a major backdrop for the story.
That shift gives the fourth season a different atmosphere while retaining the investigative, action-driven approach that has become central to the series.
Reacher faces a different kind of challenge
The new season is not simply a continuation of the previous story. Reacher is once again operating largely on his own terms, but the circumstances surrounding the latest case put him in a situation that carries both professional and personal consequences.
The story begins with an apparently isolated incident before gradually revealing a more complicated threat. As Reacher investigates, the stakes increase and the case becomes increasingly difficult to contain.
The season also introduces a potential romantic complication involving Lila Hoth, adding another personal dimension to a character who generally keeps emotional relationships at arm’s length.
Season 3 set a high bar for the series
The fourth season arrives after a strong run for the Prime Video series.
According to figures reported for Season 3, the previous season reached 54.6 million viewers globally within its first 19 days, giving the show significant momentum heading into its next chapter.
That success has raised expectations for Alan Ritchson’s return as Reacher. The fourth season brings a new investigation, a new setting and another adaptation from Lee Child’s long-running book series.
What happens after Episode 4?
There will be four more episodes following “Karambits and Pieces.”
Episode 5, titled “Bridge,” is scheduled for August 26. Episode 6, “Plum Out of Luck,” follows on September 2, while Episode 7, “Vote for Sampson,” is scheduled for September 9.
The season concludes with Episode 8, “Cut,” on September 16.
For viewers who prefer to binge-watch, that means the entire eight-episode season will be available after the finale arrives, while weekly viewers can follow Reacher’s latest case through September.
‘Neagley’ arrives after the Season 4 finale
The Reacher universe is also expanding beyond the main series.
The spinoff Neagley, starring Maria Sten as Frances Neagley, is scheduled to debut with all eight episodes of its first season on the same day as the Reacher Season 4 finale.
That gives fans another series to move on to once the fourth season concludes and expands the franchise beyond Jack Reacher’s individual story.
‘Reacher’ Season 5 is already in development
The main series is also set to continue. Reacher Season 5 has been renewed and is based on Lee Child’s novel Make Me.
The fifth season is expected to arrive in 2027, although viewers should rely on Prime Video for the official release date once it is announced.
For now, the immediate focus is Episode 4. With “Karambits and Pieces” scheduled for August 19, Reacher’s latest investigation is about to enter its next phase.
