Reacher Season 4 follows Jack Reacher through a deadly Philadelphia conspiracy that begins after a troubling subway encounter and involves a missing flash drive, government agents, and professional soldiers.
The season adapts Lee Child’s Gone Tomorrow and shifts the story from New York to Philadelphia, while adding greater emotional pressure and a heavier focus on large-scale action.
The story continues through political intrigue surrounding John Sampson and introduces new characters, while the finale leads into the Neagley spin-off and a potential Make Me-based Season 5.
Jack Reacher is back on Prime Video, and this season starts with a mistake. A late-night subway ride in Philadelphia goes wrong. A stranger dies. A conspiracy opens. Season 4 premiered on August 12, 2026, with three episodes at once and five more releasing weekly every Wednesday through September 16.
This guide covers every episode, every regional drop time, and what to expect from each chapter of the season.
Prime Video opened Season 4 with three episodes on August 12. One new episode drops each Wednesday until the finale.

Episode 4, "Karambits and Pieces," arrives on August 19, 2026, at 12:00 AM PT / 3:00 AM ET. The karambit is a curved blade with Southeast Asian origins. Its place in the title signals a specific fight sequence and the international thread running through the season's conspiracy. Prime Video has not released synopses for Episodes 4 through 8.
According to Amazon, a chance encounter on a Philadelphia subway pulls Reacher into a deadly mystery centered on a missing flash drive containing secrets worth killing for. Reacher, detective Tamara Green, and Jacob Merrick face government agents and professional soldiers, all after the same target.
The season adapts Gone Tomorrow, Lee Child's 13th Reacher novel. Philadelphia replaces New York City as the setting, giving the season a grittier visual tone. Alan Ritchson told Men's Journal the production felt like a "labyrinth of fights" and told Collider the crew shot eleven fights in the first four weeks.
The season carries emotional weight too. A split-second error on the subway leaves Reacher with guilt that is unfamiliar territory for the character.
Prime Video has not released per-episode synopses for Episodes 4 through 8. These are title-based interpretations, not confirmed plot details.
Episodes 1–3: Philadelphia's nickname opens the season with irony. "Cage Fight" signals early escalation. "One Small Step" points to a decision with larger consequences.
Episode 4 — "Karambits and Pieces": An unusual weapon. A precise fight. An international dimension to the conspiracy coming into view.
Episode 5 — "Bridge": A structure, a connection, or a turning point. At episode five of eight, the positioning fits.
Episode 6 — "Plum Out of Luck": The sharpest title in the set. Someone's options are gone. At this stage, that could be anyone.
Episode 7 — "Vote for Sampson": Politician John Sampson sits at the heart of the conspiracy. This episode brings the political thread into direct focus before the finale.
Episode 8 — "Cut": The final cut. A clean break. Prime Video has not revealed how Season 4 ends.
Alan Ritchson returns as Jack Reacher, having personally overseen fight choreography since Season 3.
Sydelle Noel plays Tamara Green, a Philadelphia detective. AGNEZ Mo plays Lila Hoth, tied to the conspiracy and to Sampson. Anggun plays Amisha Hoth, Lila's mother.
Both are making English-language television debuts. Marc Blucas plays John Sampson, a former military officer central to the mystery. Christopher Rodriguez-Marquette plays Jacob Merrick, replacing Jay Baruchel, who departed during production. Kevin Corrigan and Kathleen Robertson appear in supporting roles. Maria Sten leads the Neagley spin-off, premiering separately on September 16.
Reacher Season 4 is exclusive to Amazon Prime Video. It is not on Netflix, Paramount+, or any other platform. All subscription tiers, including the ad-supported plan, carry the show. No add-on is required.
Watch at primevideo.com, via the app on iOS and Android, or on Fire TV, Roku, and Apple TV. All three previous seasons are also available. Each adapts a separate novel with a new cast, so Season 4 is fully accessible without prior viewing.
The Season 4 finale releases on September 16, 2026. On the same day, Prime Video drops all eight episodes of Neagley Season 1 at once. The spin-off follows Frances Neagley as a private investigator in Chicago, looking into a suspicious death from her past. Ritchson is expected to appear in some capacity. The day the Philadelphia story closes, a new one opens in Chicago.
Prime Video confirmed Season 5 in May 2026. The source material is widely expected to be Make Me, the 20th Reacher novel, signalled by a Prime Video image of Ritchson holding the book. Make Me is a slow-burn small-town mystery, structurally unlike Season 4's urban political thriller. No production timeline has been confirmed.
Season 4 raises the standard on every front. Stronger source material, scaled-up action, a spin-off launching on finale day, and Season 5 already pointed toward a different kind of story. The schedule runs through September 16. Every Wednesday delivers the next chapter.
Reacher Season 4 is streaming now on Amazon Prime Video. New episodes drop every Wednesday at 12:00 AM PT / 3:00 AM ET. The season finale and Neagley Season 1 both premiere September 16, 2026.
