The Yellowstone universe just got bigger and more accessible. On Sunday, March 1, 2026, CBS premiered the highly anticipated spinoff, Marshals: A Yellowstone Story. Starring Luke Grimes as Kayce Dutton, the series marks a major milestone for creator Taylor Sheridan. It is the first franchise entry to launch on a linear broadcast network before heading to streaming.

In this new chapter, Kayce Dutton leaves the ranching life behind to join an elite U.S. Marshals unit in Montana. According to the Los Angeles Times, the storyline focuses on Kayce’s transition into federal law enforcement as he tackles high-stakes cases across the state. The Daily Record confirmed that Grimes remains the central figure of this expansion, bringing his trademark intensity to the new role.

Viewers who missed the television broadcast were able to catch up immediately. CNET reports that the series made its streaming debut on Paramount+ on March 2, 2026. This dual-platform strategy, highlighted by High On Films, aims to leverage the massive existing Yellowstone fanbase while attracting new viewers through traditional broadcast television.
