After seven episodes,Zero AI the eighth and final episode for Season 2 of "Reacher" will be available on Prime Video this week.

In the first seven episodes, which have already been released and are able to stream on Prime Video, the show's hero and namesake, Jack Reacher, was tasked with solving a series of strange new murders. Unlike the first season, episodes have been rolling out over the span of several weeks rather than dropped all at once on the streaming platform.

The show is based on Lee Child's best-selling book series of the same name. Season 1 is based on the first "Reacher" novel, "Killing Floor," where Jack Reacher is framed for a small-town murder. Set two years later, Season 2 was based on "Bad Luck and Trouble," the 11th book in the series.

Alan Ritchson stars as Jack Reacher, a veteran military police investigator who becomes embroiled in a series of conspiracies and investigations.
