Lonesome Dove (1989)

Texas, late-1800s. Two retired Texas Rangers, Augustus "Gus" McCrae and Woodrow Call, run a cattle ranch outside the small town of Lonesome Dove. The quiet life is not for them and the ranch is not prospering so when a fellow ex-Ranger, Jake Spoon, arrives and tells them of the opportunities in Montana and suggests they move there, they consider his suggestion. Soon they have made up their minds and embark on an epic 1,500-mile journey, facing dangers on all sides.
