Reacher season 4 has arrived, and our favorite morally gray ex-military hero is back in action. Though it's a faithful adaptation of the eighth novel in Lee Child's Jack Reacher series, the new season changes locations to none other than Philadelphia, the "City of Brotherly Love."
After witnessing a tragic subway bombing, Reacher finds himself tangled in a brand new mess of espionage and terror plots. Star Alan Ritchson told us during our Reacher season 4 set visit that it was, without a doubt, the best season yet... and that we can expect more action than ever before.
Below, we've put together a guide on Reacher season 4's confirmed release date, cast, plot details, trailers, and more. For all you need to know about one of the most exciting upcoming shows, not to mention one of the best Prime Video shows, scroll on...
Reacher season 4 release date
Reacher season 4 hit Prime Video on August 12, 2026.
Ritchson previously took to Instagram to share the news, writing, "We got a heavy one-two punch coming your way," adding that Reacher spin-off show Neagly will hit Prime one month after Reacher season 4, on September 16. Entertainment Weekly later added that Reacher season 4 will kick off with a three-episode premiere.
Reacher season 4 plot speculation
As we know, the series as a whole is based on Lee Child's works, with each season exploring a separate book. Season 1 was adapted from book 1, The Killing Floor, season 2 was taken from book 11 , Bad Luck and Trouble, and season 3 is based on book 7, The Persuader. Reacher season 4 will adapt Child's 13th Reacher book, Gone Tomorrow.
Released in 2009, Gone Tomorrow sees Reacher roam the streets of New York in search of a dangerous terrorist. However, the opening largely takes place in the NYC subway system, where Reacher notices a suspicious-looking passenger who he thinks may be a suicide bomber. Not only this, but the story sees Reacher partake in subway surfing, a dangerous activity where people cling onto moving subway cars.
However, because Reacher season 2 took place in New York City, the location has been moved to Philadelphia... but the story of Gone Tomorrow still stands. Per the official synopsis: "Jack Reacher is drawn into a deadly mystery on a late-night subway ride after a chance encounter with a distraught stranger goes horribly wrong, pulling him deep into a high-stakes web of government secrets and ruthless political power."
Reacher season 3 recap and ending explained
Reacher season 3 saw the ex-soldier go to his most vulnerable state yet as we went undercover and lived in enemy territory. In order to find a lost DEA informant named Teresa, Reacher posed as a wannabe bodyguard to gain access to a dodgy rug import business involved in shady dealings. However, once inside it became apparent that a dark figure from Reacher’s past who he thought he had killed years ago, Xavier Quinn, was in control of the whole thing.
With Reacher out for revenge and DEA agent Susan Duffy hellbent on finding her informant, the season came to a fiery end with Reacher pointing a gun at the man he hates most. For more on that, check out our Reacher season 3 ending explained guide.
However, as each season of Reacher follows a separate story, we don't think season 4 will continue the New England Storyline. But some characters from season 3 could well show up in the next installment just as seasons 1 and 2 stars, such as Maria Sten's Franic Negaley, have appeared in following seasons.
Reacher season 4 cast: predicted returning cast members
The show shakes up the cast every season due to Reacher landing in a brand new town each time, so expect to see some fresh faces.
Most notably, Jay Baruchel will not be returning as Jacob Merrick due to personal matters, and the role will instead go to Barry actor Christopher Rodriguez-Marquette. Jacob is set to have a much "meatier" role this season, as per Deadline (though Baruchel will indeed be back for Reacher season 5).

The official trailer dropped in July 2026, one month ahead of release.

The police pick up Reacher for the crime, but soon after escaping their clutches, Reacher sets out to solve the death, which he thinks was suspicious. Reacher meets up with the woman's brother (Christopher Rodriguez-Marquette), who is adamant she didn't kill herself. From then on, the two are pulled into a dangerous web of criminal activity.
Is Reacher season 4 the final season?
