The team includes Pete Calvin (Logan Marshall-Green), Belle Skinner (Arielle Kebbel), Andrea Cruz (Ash Santos), and Miles Kittle (Tatanka Means). Together, they serve as the last line of defense in a region defined by sprawling terrain and rising violence — a job that takes a heavy emotional toll. For Kayce, that means balancing duty with the fractured but vital relationships in his personal life.

Brecken Merrill returns as Tate Dutton, while Gil Birmingham and Mo Brings Plenty step back into their roles as Thomas Rainwater and Mo from the Broken Rock Reservation.

Y: Marshals arrives on the heels of Yellowstone’s divisive Season 5 finale, which aired late last year and closed out the original series with plenty of strong feelings from fans. Unlike previous spin-offs — 1883 and 1923 — which traveled backward in time and expanded the Dutton mythology through their ancestors, this one pushes the story forward. It also marks the first major spin-off centered on a modern-day Dutton after Kevin Costner’s exit and the franchise’s shift toward multiple new series. Projects like 1944 and The Madison remain in development, but Y: Marshals will be the first to test how far the contemporary Dutton storyline can stretch.
