The Yellowstone universe just got a whole lot bigger. On March 1, 2026, CBS and Paramount+ officially premiered Marshals, the highly anticipated spin-off starring Luke Grimes as Kayce Dutton. The series follows the youngest Dutton son as he leaves the Yellowstone Ranch behind to take on a new mantle as a U.S. Marshal in the rugged landscape of Montana.

Created by Spencer Hudnut, the series marks a significant shift for the franchise by moving the action from the ranch to the world of federal law enforcement. Logan Marshall-Green joins the cast in a lead role, telling CNET that the show is "more than a procedural" and focuses deeply on the psychological toll of the job. While the focus is on new territory, fans can expect familiar faces; TVLine reports that several original Yellowstone characters join the main cast in the opening episodes.

The premiere has already generated significant buzz for its gritty tone and high-stakes storytelling. According to Paramount+, the debut helped the franchise maintain its status as a ratings powerhouse. With Kayce Dutton now operating under federal authority, the show explores a different side of Montana justice that keeps the spirit of the original series alive while forging its own path.
