Season 4 of Reacher arrives on Prime Video this Wednesday, August 12, 2026. This installment moves the action to Philadelphia, centering on a mystery triggered by an incident on a late-night subway train. The season draws inspiration from the Lee Child book Gone Tomorrow, though viewers should expect modifications to the original plot throughout the eight-episode run.

Prime Video drops the first three episodes at once on the premiere date. Subsequent installments will roll out on a weekly basis, arriving at 3:00 A.M. Eastern Time. The final episode is scheduled for September 16, 2026.

Following the conclusion of this season, a spin-off series focusing on the character Neagley will debut in its entirety on the same day the Reacher finale airs. Production is already moving forward for Season 5, which adapts the book Make Me and carries a projected 2027 release date.

Alan Ritchson returns as the lead, promising a high volume of action sequences. Those interested in the production details can find reports in the current Men's Journal Summer Entertainment Special.
