Mayor of Kingstown Season 4: Will the Russians Strike Back?

Mayor of Kingstown finally slammed the door on its Russian mob arc, and not subtly. Season 3 wrapped with both Milo and Konstantin dead, clearing the board for a new season that is very much not the same game. Creator Hugh Dillon told THR that the Russians being taken off the map creates a vacuum, and Season 4 is about who rushes in to fill it. Short version: Mike is out of comfort zones and surrounded by people who do not care about his rules.

How the Russians went down

The Season 3 finale, fittingly titled 'Comeuppance' (aired August 2024), ends the Milo vs. Mike saga for good. On Konstantin's yacht, Milo taunts Mike about his mother's death one last time. Mike answers with two point-blank shots. As one review put it, no one walks away from that range.

Konstantin fares no better. Milo forces Iris into an impossible choice: shoot Konstantin or die. She pulls the trigger. That leaves Mike to try and wipe out the rest of the operation with an ambush set up alongside Bunny on the Sixth Street Bridge. The plan misfires, literally, gunfire pops off too early, cars crash, SWAT piles in, and the resulting shootout shreds both Konstantin's crew and Bunny's gang. Messy, costly, final. The Russian presence in Kingstown is done.

Season 4 shifts the fight

With the Russians gone, the power vacuum does exactly what you expect: it attracts people who want the keys to the city. Dillon says that is the point of Season 4, which hits Paramount+ on October 26, 2025.

Enter two big new problems for Mike McLusky: a warden who refuses to play ball and a gangster with Detroit credentials that travel.

'She is making the decisions. She is calling the shots. It ain't Mike's world. It's her world, and we're going to watch this battle between the two of them.'

Edie Falco is Nina Hobbs, the new boss at Anchor Bay Correctional Facility. She is not interested in Mike's handshake politics. In the trailer, she basically plants a flag and tells him the prison is her castle now. That alone is enough to blow up his entire system.

Meanwhile, Lennie James plays Frank Moses, a long-respected Detroit crime figure who smells opportunity. James has said Frank came to fill the Russian-sized hole in Kingstown and will both work with and work against Mike while bonding with Bunny. Translation: a three-way power dance where alliances shift depending on the day and the money.

• Edie Falco joins as Nina Hobbs, a hardline warden at Anchor Bay who refuses to collaborate with Mike.
• Lennie James debuts as Frank Moses, a Detroit legend moving in to build his operation amid the vacuum.
• The trailer shows Hobbs staking her claim over the prison, while Frank starts triangulating between Mike and Bunny.
• Laura Benanti boards as Cindy Stephens, a newly recruited correctional officer who is stepping into a powder keg.
• The Aryan Brotherhood problem from Season 3 is still not resolved, which is exactly as bad as it sounds.

Kyle's mess is priority one

All that would be enough, but Mike also has a family crisis that could get him killed faster than any rival. Kyle was arrested after shooting SWAT officer Robert during the bridge chaos. Kyle says he fired because he saw Robert about to shoot a civilian, but there were plenty of witnesses and none of this is simple. Mike's immediate priority is getting his brother out alive.

'The biggest challenge is to get my brother out of jail and keep him safe.'

One grim note from the Season 4 trailer: Mike tells Kyle the only time he is going to be safe is when he is in his cell. That is not a pep talk, it is the reality of Kingstown's food chain.

How hot does it get?

Dillon is calling Season 4 'incendiary' and says the blade is sharper and the cuts go deeper. Between a warden who will not bend, a Detroit heavyweight moving in, and a town already teetering after the bridge bloodbath, it tracks.
