Mayor of Kingstown fans, buckle up. The gritty prison-town drama is coming back for a fourth season—and things are looking messier than ever. Jeremy Renner is returning as Mike McLusky, the reluctant fixer caught in the middle of Kingstown’s tangled web of gangs, cops, and corruption. After a brutal Season 3 finale, there’s a lot to unpack about what’s next. Here’s what’s known so far, from when we might see new episodes to who’s coming back—and who isn’t.
Release Date Rumors: When Will Season 4 Hit Screens?
There’s no official release date yet, but the pieces are falling into place. Renner confirmed back in January 2025 that filming was already underway, and production wrapped up in Pittsburgh by May. That puts the show right on track with its usual schedule.
Season 3 came out in June 2024, which was about 15 months after Season 2 ended. If Season 4 follows that same rhythm, we’re probably looking at a fall 2025 release. In fact, Paramount has hinted at an October launch, slotted in between Tulsa King and Landman on its fall slate. If that holds, fans can expect a trailer sometime in September.
Cast Updates: Who’s Returning and Who’s New?
Jeremy Renner is firmly back as Mike, which is especially meaningful after everything he’s been through following his 2023 snowplow accident. His return is not just about continuing the story—it’s personal for a lot of fans who’ve followed his recovery.
As for the rest of the core cast, several key players are expected to return, including:
-
Hugh Dillon as Ian, whose reckless actions are finally catching up to him.
-
Taylor Handley as Kyle, now in jail after that Season 3 cliffhanger.
-
Tobi Bamtefa as Bunny, who’s taken control of the streets but might not hold them for long.
-
Hamish Allan-Headley as Robert, caught in the crosshairs of an internal probe.
-
Necar Zadegan as Evelyn Foley, whose investigation into police corruption could shake the whole town.
That said, Season 3 didn’t pull punches—major characters like Iris (Emma Laird), Kareem (Michael Beach), and Milo (Aidan Gillen) didn’t make it out alive. So expect some fresh blood in Season 4, including some big-name talent:
-
Edie Falco joins as Nina Hobbs, the new no-nonsense warden at Anchor Bay.
-
Lennie James plays Frank Moses, a veteran gangster ready to claim his piece of Kingstown.
-
Laura Benanti comes in as Cindy Stephens, a new corrections officer.
-
Clayton Cardenas is Deputy Warden Torres, working under Hobbs’ command.
These new faces will likely rattle the already shaky balance between the prison and the streets.
What to Expect Next: Plot Predictions and Themes
Season 3 left the power structure of Kingstown in chaos. With Milo dead and the Russian mafia out, Bunny’s crew—backed by the police—has taken over. But co-creator Hugh Dillon has warned that “a vacuum” is never safe for long. Gangs don’t stay dormant, and new enemies are bound to show up.
Mike’s in a tight spot. His brother Kyle is behind bars. Ian’s being investigated. Robert’s under fire. And Evelyn—the one person he might trust—is now digging into everything he’s connected to. Their secret affair? That’s likely going to get a lot more complicated.
Meanwhile, Bunny’s rise might start to threaten Mike’s influence. And with the Aryan Brotherhood still out there, payback could be around the corner. There’s also emotional fallout still lingering—Mike is still dealing with Iris’ death and the weight of everything he’s had to do to hold this town together.
Dillon teased that Season 4 is going to be “rock ‘n’ roll”—louder, faster, and even more relentless than before. Expect the themes of guilt, loyalty, power, and survival to hit even harder this time around.
