Yellowstone prequel series
The Dutton family (including Shea, the great-grandfather of the character played by Kevin Costner in Yellowstone) leave Tennessee after the Civil War and travel to Fort Worth, Texas. They joined a wagon train making the arduous journey west to Oregon, before settling in Montana to establish what would become the Yellowstone. Ranch.
Shea Brennan (Sam Elliott), a Pinkerton Agency employee leading the expedition, is a former captain who served in the Union Army during the American Civil War. His wife Helen and daughter both die of smallpox just before the expedition begins. While mourning their deaths, he cremated them by setting fire to their house and considered committing suicide, but was interrupted by the arrival of Thomas (LaMonica Garrett).
Season 2 of Y: Marshals premieres in just 12 days, on October 4, 2026, and the return already sounds like the kind of high-stakes Western drama that makes appointment TV feel essential again. After a first season that moved Kayce Dutton beyond the familiar borders of the Yellowstone Ranch and into the dangerous world of federal law enforcement, the new season opens with a brutally personal hook: Tate Dutton has been taken hostage. For viewers who follow the wider Yellowstone universe—or anyone who likes their crime drama with dust, blood, family loyalty and moral fallout—this is the week to catch up and add the series to your BetaSeries watchlist.
Y: Marshals follows Kayce Dutton, played by Luke Grimes, as he joins an elite unit of U.S. Marshals in Montana. The premise is sharp because it doesn’t simply repeat the ranch warfare of Yellowstone; it repositions Kayce as a man trying to use the skills that shaped him—cowboy instinct, Navy SEAL discipline and Dutton-family survival reflexes—in a more official, and often more psychologically punishing, arena. The result is a modern Western procedural with a serialized backbone: every case has immediate danger, but every bullet fired also echoes through family, land, tribal politics and the cost of trying to keep order in a region where violence is rarely random.
If you watched Season 1 and have been away for a while, here’s what you need to remember without getting lost in a full recap: Kayce has left the Yellowstone Ranch behind, at least geographically and professionally, but not emotionally. The show’s first 13 episodes established him as part of a U.S. Marshals team tasked with facing Montana’s escalating violence, while also carrying the old Dutton burden of family first, consequences later. Around him, the series built a strong ensemble: Logan Marshall-Green as Pete Calvin, Arielle Kebbel as Belle Skinner, Ash Santos as Andrea Cruz, and returning Yellowstone-world figures such as Gil Birmingham as Thomas Rainwater, Mo Brings Plenty as Mo, and Brecken Merrill as Tate Dutton. Season 2 appears ready to test every one of those relationships.
