Based on Lee Child’s Jack Reacher novels, Season 1 of the Prime Video series adapted Killing Floor, Child’s 1997 debut novel/first Jack Reacher tale, in which the titular man mountain (played by Titans‘ Alan Ritchson) arrived in the town of Margrave, Ga., and found a community grappling with its first homicide in 20 years — for which the new drifter in town (aka Reacher) got pinned.

Season 2 was based on Bad Luck and Trouble, the 11th book in Child’s series of Jack Reacher novels, and followed the veteran military police investigator as he reunited with members of his old U.S. Army unit in the wake of the brutal murder of one of their own.

Season 3 is based on the seventh book in Child’s best-selling series, Persuader, in which Reacher goes undercover to rescue an informant held by a foe from his past.

Maria Sten (Swamp Thing) co-stars as Frances Neagle in the first three seasons (at least), and is set to headline her own spinoff. 

There is no word yet on which of Child’s novels Season 4, which got an early pick-up in October 2024, will adapt.

Nick Santora (Prison Break) serves as showrunner on Reacher and executive-produces with Ritchson, Child, Don Granger, Scott Sullivan, Mick Betancourt, David Ellison, Dana Goldberg and Matt Thunell.
