Paramount+ has released the first full trailer for Season 4 of Mayor of Kingstown and set October 26, 2025, for the premiere, marking Jeremy Renner’s latest return as fixer Mike McLusky nearly three years after the actor’s serious snowplow accident. The footage signals a reset to the show’s prison-centric tensions, with Mike racing to prevent a new gang war as rival crews move to fill the vacuum left by last season’s upheavals.

The new season introduces Edie Falco as Nina Hobbs, a hard-line prison warden whose arrival complicates Mike’s back-channel diplomacy and reorders the power map between inmates, guards, and street factions. The trailer frames their clash as a central conflict, positioning Hobbs as an institutional counterweight to Kingstown’s unofficial “mayor.” The series, created by Taylor Sheridan and Hugh Dillon, continues to anchor Paramount+’s crime slate, with Season 4 debuting globally on a Sunday and rolling out weekly.

Storywise, Season 4 picks up in the aftermath of the Russian mob’s fall and the death of chief antagonist Milo, with the show leaning back into the mechanics of control inside and outside the walls. Alongside Renner, returning cast includes Taylor Handley, Tobi Bamtefa and others, while new additions include Lennie James as a rising kingpin and Laura Benanti as a corrections officer whose loyalties are tested. The trailer emphasizes Mike’s shifting alliances with Bunny’s crew and law enforcement, underscoring how fragile cease-fires can be when money and influence reroute overnight.

The release caps a steady build since last year’s renewal and Renner’s resumed schedule, with filming completed earlier this year. Seasons 1–3 remain available to stream, positioning the series to draw back viewers who followed Mike’s violent détente across Kingstown’s prison economy and the city’s political machinery. With a star pairing of Renner and Falco, the platform is pitching Season 4 as both a continuation and a recalibration toward the show’s original premise: mediation in a system designed to produce conflict.
