Yellowstone may have completed its five-season run, but the sprawling Dutton saga is nowhere near finished. After nearly a year of speculation about new spinoffs and follow-up series, fans finally have the confirmation they’ve been waiting for: the next chapter of the Yellowstone universe is officially on the way — and it’s arriving earlier than anyone predicted.
“Y: Marshals,” the newest Yellowstone spinoff centered on fan-favorite character Kayce Dutton, will premiere Sunday, March 1, 2026, at 8 p.m. ET on CBS.
A New Beginning for Kayce Dutton
According to the official series synopsis, the upcoming show follows Kayce (played by Luke Grimes) as he steps away from the Yellowstone Ranch and into a new life serving as part of an elite U.S. Marshals unit.
The story focuses on Kayce’s unique background — both as a Navy SEAL and a rancher — and how he uses those skills to confront escalating danger across Montana.
Plot Summary
“With the Yellowstone Ranch behind him, Dutton joins an elite unit of U.S. Marshals, combining his skills as a cowboy and Navy SEAL to bring range justice to Montana, where he and his teammates must balance family, duty, and the high psychological cost that comes with serving as the last line of defense in the region’s war on violence.”
The series promises a blend of law-enforcement action, rugged Western storytelling, and the emotional family drama Yellowstone fans love.
