1923 season 2 is set to conclude the Yellowstone spinoff show as the franchise faces a major overhaul. The prequel series follows Jacob (Harrison Ford) and Cara Dutton's (Helen Mirren) effort to protect the Yellowstone ranch from desperate ranchers and wealthy businessmen who wish to seize control and exploit the expansive land. 1923 was positioned as a two-season show when it first premiered, but in the age of constant extensions and reboots, it wasn't clear if the spinoff could continue beyond its initial story.
