The first trailer for the CBS Yellowstone spinoff TV show, Y: Marshals, has debuted!

The series stars Luke Grimes reprising his role as Kayce Dutton. 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. Kayce and his teammates – Pete Calvin (Logan Marshall-Green), Belle Skinner (Arielle Kebbel), Andrea Cruz (Ash Santos) and Miles Kittle (Tatanka Means) – must balance the high psychological cost of serving as the last line of defense in the region’s war on violence with their duty to their families, which for Kayce includes his son Tate (Brecken Merrill) and his confidantes Thomas Rainwater (Gil Birmingham) and Mo (Mo Brings Plenty) from the Broken Rock reservation.

The trailer, which can be seen above, has Luke saying, “I fought every day to get out from under the weight of the Yellowstone. I’ve lost my teammates, my parents, even my brothers. I know sometimes good men have to do bad things. But I’m trying to find a new beginning.”

The series is set to debut in a couple of months on CBS. Look out for the premiere on March 1, 2026.
