Reacher Season 4 Finale and Neagley Spinoff Premiere on Same Day

The fourth season of the action series Reacher concludes on Prime Video on September 16, 2026, with the finale titled "Cut." On the same day, the platform will debut the spinoff series Neagley, releasing all eight of its episodes at once. This scheduling provides nine new episodes set in author Lee Child's universe within a single day. The spinoff stars Maria Sten, reprising her role as Frances Neagley, a character who previously appeared as a supporting figure in the main series. Neagley follows the character as a private investigator in Chicago who begins investigating the suspicious death of a friend from her past. Alan Ritchson, who portrays Jack Reacher, will make a supporting cameo appearance in the new series, serving as a narrative link between the two shows. Reacher's fourth season has centered on a plot involving a bioweapon. The penultimate episode, "Vote for Sampson," depicted a graphic test of the weapon, a tonal shift that some analysis suggests prepares the audience for the fifth season. That upcoming season is currently in production and is based on Child's novel Make Me, which is noted for its darker subject matter. It is expected to premiere later in 2027.
