Reacher Season 4 is streaming now on Prime Video. The first three arrived Wednesday, August 12, followed by Episode 4 on August 19 and Episode 5 on August 26. Episode 6 was scheduled for September 2. Episode 7 is next on September 9, before the September 16 finale. That same day, Prime Video releases all eight episodes of Neagley, the spinoff starring Maria Sten.
The two shows share a release day, but they are separate stories. Reacher Season 4 adapts Lee Child’s Gone Tomorrow and follows Jack Reacher into a conspiracy that begins on a New York subway. Neagley follows Frances Neagley as a private investigator in Chicago after a friend dies in a suspicious accident.
This guide keeps the dates, episode plan, cast, story, and viewing order in one place so you can follow both shows without mixing their schedules.
Reacher Season 4 Release Date and Time
Reacher Season 4 is available exclusively on Prime Video in more than 240 countries and territories. Episode 7 is the next scheduled release, on September 9. Prime Video does not use one universal release time for every region, so the exact hour may vary in the local app.
There are eight episodes in the season. The remaining scheduled dates are September 9 for Episode 7 and September 16 for Episode 8.
Reacher Season 4 Episode Release Schedule
- Episodes 1–3 — August 12: available now. The premiere begins with the subway incident and the conspiracy that pulls Reacher into the case.
- Episode 4 — August 19: available now. This was the first weekly episode after the three-part premiere.
- Episode 5 — August 26: available now. This is the midpoint episode in the eight-episode season.
- Episode 6 — September 2: scheduled release date has passed.
- Episode 7 — September 9: next scheduled episode.
- Episode 8 — September 16: the Reacher Season 4 finale arrives on the same day as the full Neagley season.

What Is Reacher Season 4 About?
Season 4 is based on Gone Tomorrow, the 13th Jack Reacher novel by Lee Child. The story begins when Reacher notices a distressed woman on a subway. He recognizes warning signs that other passengers miss, but the encounter ends badly and puts him inside a much larger case.
Amazon describes the investigation as a deadly game involving ruthless enemies from the highest levels of power. That setup is a good match for the series: Reacher begins with one person in danger, follows the details that do not fit, and discovers that the problem reaches far beyond the first crime.
The adaptation does not need to copy every part of the book. Earlier seasons changed locations, combined characters, and adjusted the order of events while keeping the main mystery. Viewers can expect Gone Tomorrow to provide the foundation rather than a scene-for-scene script.
Who Is in the Reacher Season 4 Cast?
Alan Ritchson returns as Jack Reacher. The announced new cast includes Sydelle Noel, Chris Marquette, AGNEZ MO, Anggun, Kevin Weisman, Marc Blucas, Kevin Corrigan, and Kathleen Robertson. Amazon has not attached every character name to the public cast list.
Maria Sten is leading Neagley, but Amazon’s current Season 4 overview does not list Frances Neagley as a regular part of the main story. The clearest confirmed connection is the release plan: Reacher finishes on September 16, then viewers can move directly into her complete spinoff season.

When Does Neagley Premiere?
All eight episodes of Neagley premiere on September 16, 2026, immediately after the Reacher Season 4 finale. It is a full-season release, so there is no weekly wait once it becomes available.
Neagley follows Frances Neagley, Reacher’s former military protégé and a member of the Army’s 110th Special Investigations Unit. She now works as a private investigator in Chicago. After a close friend dies in what appears to be a suspicious accident, she uses her military experience and investigative skills to find out what happened.
Maria Sten returns in the title role. Greyston Holt plays Detective Hudson Riley, Adeline Rudolph plays Renee Birdwhistle, Jasper Jones plays Keno, Matthew Del Negro plays Pierce Woodrow, and Damon Herriman plays Lawrence Cole. Alan Ritchson guest-stars as Jack Reacher.
Should You Watch Reacher or Neagley First?
Watch Reacher Season 4 first if you are following both shows as they release. Prime Video designed the calendar so the main season ends before the spinoff becomes available. That order also avoids leaving the weekly Reacher story unfinished while starting a separate eight-episode mystery.
You should still be able to watch Neagley on its own. Its central case begins with a friend’s death and gives Frances a new group of characters. Knowing her history with Reacher and the 110th adds context, but the premise does not require every earlier Reacher episode.
The Neagley series page collects the latest release, cast, and story coverage for the spinoff.
How to Watch Reacher Season 4
Reacher Season 4 and Neagley are Prime Video exclusives. You need access to Prime Video through an Amazon Prime membership or the service option offered in your country. Pricing and trial availability vary by region.
All three previous Reacher seasons are also available on Prime Video. New viewers can catch up before the weekly Season 4 episodes continue, while returning viewers can revisit the 110th Special Investigations Unit episodes for more Neagley background.
- First: watch Reacher Seasons 1–3 if you want the complete television story so far.
- Next: watch Reacher Season 4 from August 12 through the September 16 finale.
