Set in the year 1923 in the United States, this story serves as a prequel to the popular series "Yellowstone" and a sequel to "1883". After enduring the challenges of World War I and the Spanish flu pandemic, Americans now find themselves confronted with additional hardships. The government has enforced Prohibition, and the looming Great Depression adds to their woes. In the midst of these trying circumstances, the elderly Dutton couple, portrayed by Ford and Mirren, must put in immense effort to protect their family ranch located in Montana. One of the obstacles they face is dealing with the claims made by the local shepherd leader, Scottish Banner Creighton.
