Jack Reacher can’t even ride public transportation without finding himself in the middle of a conspiracy. Reacher Season 4 Episode 1, “City of Brotherly Love,” wastes little time reminding viewers why Prime Video’s bruising action thriller works so well, dropping Alan Ritchson’s wandering former military investigator into Philadelphia and immediately surrounding him with suspicious federal agents, hired muscle, a missing flash drive, and a death he simply can’t walk away from.
Based on Lee Child’s Gone Tomorrow, Season 4 relocates the novel’s opening mystery from New York to Philadelphia while preserving its irresistible hook: Reacher notices a distressed stranger on a late-night subway and realizes something is terribly wrong. What follows is a lean, fast-moving premiere that gives Reacher exactly what he needs — a mystery worth solving and several people foolish enough to try stopping him.
Alan Ritchson slips effortlessly back into the role of Jack Reacher, joined this season by Sydelle Noel, Agnez Mo, Anggun, Christopher Rodriguez-Marquette, and Kevin Corrigan. The premiere wisely surrounds its familiar hero with an entirely new collection of characters and immediately establishes that almost everyone Reacher encounters knows more than they’re willing to say.
A SUBWAY RIDE CHANGES EVERYTHING
“City of Brotherly Love” opens with one of those wonderfully simple Reacher setups that immediately demands attention.
After a night out in Philadelphia, Reacher boards a subway and notices a visibly distressed woman sitting alone. Her behavior, heavy clothing despite the warm weather, and concealed hands lead his military-trained instincts toward a terrifying possibility: she may be carrying a bomb.
Reacher approaches carefully and tries to talk her down. There is no bomb, but the situation is hardly less dangerous. The woman eventually produces a revolver and, despite Reacher’s attempt to convince her that he can help, takes her own life.
Her name is Anna Merrick, and Reacher soon learns she held a sensitive government position.
That alone would probably be enough to spark his curiosity. Then federal agents arrive asking whether Anna gave him something before she died.
Specifically, they’re looking for a flash drive.
Reacher says she gave him nothing.
They don’t believe him.
REACHER DOES WHAT REACHER DOES BEST
It wouldn’t be Reacher without somebody making the catastrophic mistake of assuming the giant man standing in front of them can be intimidated.
Two men confront Reacher outside the police station demanding the same flash drive.
They quickly discover their mistake.
The resulting fight provides the premiere with its first real burst of physical action, but more importantly, it confirms that whatever Anna was involved with reaches far beyond a routine government investigation.
Reacher now has multiple groups searching for something they believe he possesses.
And if there’s one reliable way to make Jack Reacher interested in your conspiracy, it’s sending people to beat him up.
ANNA MERRICK BECOMES MORE THAN A MYSTERY
The episode gets considerably more interesting when Reacher meets Jacob Merrick, Anna’s brother and a New Jersey police officer.
Until this point, Anna could easily have functioned as little more than the catalyst for the season’s mystery. Jacob gives her death emotional weight.
He describes his sister as a good person and reveals more about her government work, giving Reacher another reason to question why she was terrified enough to believe nobody could help her.
That conversation changes Reacher’s involvement.
He wasn’t looking for another case. He rarely is.
But someone is dead, powerful people are clearly hiding something, and her grieving family deserves answers.
For Reacher, that’s enough.
EVERYONE WANTS THE FLASH DRIVE
The missing flash drive quickly becomes the premiere’s MacGuffin, but the episode wisely makes the mystery surrounding it more interesting than the object itself.
Federal agents want it.
Street-level attackers want it.
And Reacher doesn’t even have it.
The mystery expands further with the arrival of Lila Hoth and her mother, who claim the drive contains damaging information connected to a powerful congressman with presidential ambitions.
Whether everything Reacher is being told can be trusted is another question entirely.
That uncertainty gives Season 4 a strong foundation. Instead of immediately revealing who the villains are, “City of Brotherly Love” surrounds Reacher with competing factions whose motivations remain deliberately unclear.
ALAN RITCHSON REMAINS THE PERFECT REACHER
Four seasons in, Alan Ritchson understands exactly what makes this character entertaining.
The physicality is obviously important, but Reacher works because Ritchson plays him with an almost absurd level of certainty. He observes something, processes the available information, reaches a conclusion, and moves forward.
Everyone else is still trying to understand the situation while Reacher is already three deductions ahead.
The premiere also remembers something equally important: Reacher is funny.
His deadpan exchanges with Detective Tamara Green and the federal agents keep the episode from becoming overly grim, while the growing mystery gives Ritchson plenty of opportunities to demonstrate why Reacher’s brain remains every bit as dangerous as his fists.
PHILADELPHIA GIVES SEASON 4 A FRESH START
Moving Gone Tomorrow from Manhattan to Philadelphia initially sounds like a relatively minor adaptation choice, but “City of Brotherly Love” makes good use of its new setting.
Reacher moves through subway stations, police precincts, diners, libraries, and city streets as someone who remains fundamentally disconnected from wherever he happens to be.
That outsider quality has always been essential to the character.
Reacher belongs everywhere because he belongs nowhere.
Season 4 appears ready to use Philadelphia as more than scenery, and the premiere establishes enough personality to make the city feel like an important part of the mystery rather than simply another stop on Reacher’s endless journey.
Final Verdict
“City of Brotherly Love” is exactly the kind of season premiere Reacher needed.
There’s no unnecessary reinvention and very little wasted time. A seemingly random encounter leads to a suspicious death, the suspicious death leads to a missing flash drive, the flash drive attracts several dangerous factions, and Jack Reacher decides he wants answers.
Simple.
Effective.
And extremely Reacher.
Most importantly, the premiere establishes a mystery worth following without sacrificing the action, humor, deductive reasoning, and imposing Alan Ritchson performance that have turned the series into one of Prime Video’s signature franchises.
Season 4 is off to a very promising start.
Ending Explained
The ending turns what initially looks like a relatively straightforward missing-flash-drive mystery into something considerably larger.
Reacher spends most of the premiere dealing with people who believe Anna gave him the drive before her death. He knows she didn't, but that doesn't matter to the people hunting it. The more aggressively they pursue him, the more convinced Reacher becomes that Anna discovered something important enough to get her killed.
Lila and her mother add another piece to the puzzle by connecting the missing information to a powerful politician, but Reacher still doesn't have enough information to know which version of events — or which people — he should trust.
Then the episode flips the power dynamic.
Reacher has spent the hour effortlessly handling street-level attackers, only to encounter a much more capable group of professionals. He's tranquilized, abducted, and wakes up imprisoned in a cell.
That's the real cliffhanger.
Someone finally managed to get the drop on Jack Reacher.
More importantly, it tells us that the people behind Anna's death aren't simply sending disposable muscle after him. Reacher has wandered into an organized operation with the resources and training necessary to capture someone like him.
Episode 2 now begins with two immediate questions:
Who captured Reacher — and what do they think he knows?
