Jack Reacher is back on the move, and this time trouble starts on a Philadelphia subway. Reacher season 4 has landed on Prime Video, and if you’re trying to keep track of when new episodes drop, who’s in the cast, and what the story is actually about, you’re in the right place.
When Does Reacher Season 4 Come Out?
Reacher season 4 premiered on Prime Video on Wednesday, August 12, 2026, with the first three episodes dropping all at once. After that opening batch, new episodes release weekly, every Wednesday, right through the season finale on September 16, 2026.
New episodes usually land at 12:00 a.m. Pacific Time, which is 3:00 a.m. Eastern Time, so if you’re an early riser on the East Coast, you can watch before work.
Here’s the full episode schedule so you don’t miss a drop:
- Episodes 1–3: August 12, 2026
- Episode 4: August 19, 2026
- Episode 5: August 26, 2026
- Episode 6: September 2, 2026
- Episode 7: September 9, 2026
- Episode 8 (finale): September 16, 2026
One more thing worth knowing: the same day the season 4 finale drops, the spinoff series Neagley — starring Maria Sten — releases its entire first season on Prime Video. So the moment one Reacher story wraps up, another one from the same world kicks off.
What Is Reacher Season 4 About?
Season 4 is based on Gone Tomorrow, the thirteenth book in Lee Child’s Jack Reacher series, and it moves the action to a much more urban setting than past seasons. Reacher spent season 3 in a small town near Portland, Maine. This time he’s in Philadelphia.
The story kicks off when Reacher witnesses something disturbing on a late-night subway ride: a distraught woman who appears to be showing every sign of a suicide bomber. What happens next pulls him into a tangled, high-stakes mystery involving crooked cops, powerful political figures, and a network operating far above street level.
Even if you’ve already read Gone Tomorrow, the show takes some real detours from the book. Character names have changed, a few subplots have been reworked, and the show’s writers clearly wanted a few surprises for longtime readers, not just newcomers.
Who’s in the Reacher Season 4 Cast?
Reacher has always rebuilt most of its supporting cast every season, and season 4 keeps that tradition going. Alan Ritchson is really the only major face returning in a regular role — everyone around him is mostly new.
Returning Cast
- Alan Ritchson as Jack Reacher – the towering, wandering ex-military cop at the center of it all. This is Ritchson’s fourth season in the role, and season 5 has already been confirmed.
New Cast for Season 4
- Sydelle Noel (GLOW, Black Panther) as Tamara Green, a detective pulled into the case
- Kevin Corrigan as Detective Shaun Docherty, Tamara’s partner
- Christopher Rodriguez-Marquette as Jacob Merrick
- AGNEZ MO as Lila Hoth, marking her first English-language TV role
- Anggun as Amisha Hoth, presented as Lila’s mother
- Kevin Weisman as Russell Plum, a freelance investigative journalist
- Marc Blucas as Congressman John Sampson
- Kathleen Robertson in a key new role for the season
Maria Sten’s fan-favorite character, Frances Neagley, isn’t part of the main season 4 lineup this time. She may show up briefly, but she’s mostly busy leading her own spinoff, Neagley, set in Chicago.
Where Can You Watch Reacher Season 4?
Reacher season 4 is streaming exclusively on Amazon Prime Video in the USA. You’ll need an active Prime Video subscription, and Amazon offers both an ad-supported plan and an ad-free premium tier, so pick whichever fits your budget.
There’s no cable option and no separate rental or purchase available — a Prime Video membership is the only way to stream it. If you don’t already have Prime, Amazon does offer a free trial period, which is worth checking if you just want to catch up before the finale airs.
How Many Episodes Does Reacher Season 4 Have?
Reacher season 4 runs for eight episodes total, matching the episode count of every previous season. Season 3 was Prime Video’s most-watched season on the platform since Fallout season 1, so expectations for season 4 are high.
Is Reacher Coming Back for Season 5?
Yes. Reacher has already been renewed for season 5, so Alan Ritchson will be back on the road again after this season wraps. Amazon hasn’t released a story or cast breakdown for season 5 yet, but given the show’s track record, expect an announcement not long after season 4 finishes its run.
