'Reacher' Season 4 Trailer: Biggest and Most Violent Yet, Premiering on Prime Video

Full text

According to Prime Video, Alan Ritchson's Jack Reacher is back and bigger than ever in Reacher season 4, which is just as well, as the first trailer shown at San Diego Comic-Con gives us a glimpse at his most dangerous mission yet.

The trailer, which you can watch above, opens with Alan Ritchson's ex-soldier sitting inside a subway car when he witnesses a woman end her own life. 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.

At one point, Reacher is told to walk away. But, of course, our favourite lucky hero does no such thing, as he is prepared to beat down as many bad guys as it takes to get to the bottom of the murder. However, it looks like season 4's villain has connections in high places, as Reacher's dedication to cracking the case quickly makes him a wanted man. Plus, it wouldn't be a season of Reacher without a romantic subplot thrown in, and it looks like Reacher will hook up with a young journalist played by AGNEZ MO.

The action series' fourth outing adapts author Lee Child's thirteenth Jack Reacher book, Home Tomorrow. The official synopsis from Prime Video reads, "When a chance encounter with a distraught stranger on a subway goes horribly wrong, Jack Reacher is drawn into a complex and deadly game that pits him against ruthless foes from the highest echelons of power."

Also at Comic Con, the Reacher and Neagley panel revealed the first trailer for the upcoming Frances Neagley spin-off. The trailer, which has since been shared by Prime Video on YouTube , gives us a glimpse of Reacher's once right-hand woman as she and her PI squad take down criminals connected to the death of her beloved friend.

Reacher season 4 starts streaming on Prime Video from August 12, and Neagley season 1 premieres right after on September 16. Stay up to date with this year's San Diego Comic-Con with our SDCC 2026 live blog and our SDCC 2026 schedule .
