When will the final episode of Reacher season 4 be released?

Season 4 has been a huge hit! According to data from Luminate, this new adventure shattered viewership records, amassing 5.3 million views in just two days. This success further cements Reacher’s status among the most-watched titles on Prime Video.

Without a doubt, numerous subscribers are eagerly awaiting the season 4 finale. Episode 8, titled “Blood for Blood,” will premiere on Wednesday, September 16, 2026, at 9 AM. Unlike the previous seven episodes, this one will run a bit longer, clocking in at exactly 56 minutes.

What can viewers expect?

This explosive finale will revisit the conspiracy surrounding the photograph of Anna Merrick (Karen Kwong-Chip) and the fate of some characters at the end of episode 7. Indeed, Jack Reacher captures chemist Leo Ahlquist (Shawn Doyle) and coerces him into revealing the origins of the plot.

Operation Mongoose is a covert operation conducted in Indonesia with the help of General Putra. The photo of Anna Merrick seems innocuous, but a whiteboard visible in the background actually contains the formula for a massive chemical weapon. Thanks to AI technology, this formula can now be deciphered.

Lila (Agnez Mo) and Amisha (Anggun) now possess the secret formula, as well as the raw materials and expertise needed to activate this weapon, and importantly, to test it! In the final moments of the episode, the weapon is activated underwater after John Sampson (Marc Blucas) dives into a river with a suicide bomber. At the end, it’s unclear whether he is alive or dead.

Lila and Amisha still have the means to produce the weapon, posing a real threat for the end of season 4. The question remains whether they will activate it! Find out on September 16, 2026, on Prime Video!
