The 'Yellowstone' universe expands with 'Marshals,' coming to CBS on Sunday, March 1. Luke Grimes returns to TV as Kayce Dutton, who 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 Mo (Mo Brings Plenty) and Thomas Rainwater (Gil Birmingham) from the Broken Rock reservation. Episodes will also stream on Paramount+.
