Prime Video has announced that Reacher season 4 will premiere on August 12. The action series starring Alan Ritchson returns to the streamer with an adaptation of Lee Child’s 13th Jack Reacher novel, Gone Tomorrow.

The streamer’s update also confirmed that the Reacher universe will expand this year with Neagley, a new series set in the same continuity. Reacher has already been renewed for a fifth season.

Season 4 adapts Gone Tomorrow and adds a key ally

The fourth season is based on Lee Child’s Gone Tomorrow. Christopher Rodriguez-Marquette joins the cast as Jacob Merrick, a small-town police officer who becomes Jack Reacher’s primary ally during the season’s central investigation.

Gone Tomorrow opens with Reacher witnessing an apparent suicide on a New York City subway. The woman is linked to the Pentagon, and her death pulls Reacher into a conspiracy involving a corrupt politician, Al Qaeda operatives and multiple assassins.

Plot stakes and central mission for Reacher

In the season’s storyline, Reacher and Jacob Merrick race to unravel why Susan Mark killed herself, locate her missing child and survive threats from powerful enemies. The investigation forces Reacher to move quickly against a network that connects government corruption and terrorism.

The casting of Jacob Merrick positions the new character as both an entry point into local law enforcement and a counterbalance to Reacher’s solitary methods.

Release and expanded universe details

Reacher season 4 debuts on Prime Video on August 12. The announcement arrives alongside news that Neagley, a series set within the same universe, will premiere later this year.

Prime Video has also confirmed that Reacher is returning for a fifth season, ensuring the franchise will continue beyond the upcoming adaptation.
