Yellowstone (2018)

John Dutton III (Kevin Costner), a sixth-generation widower in the Dutton family owns and operates the Yellowstone Dutton Ranch, the largest contiguous ranch in the United States. His youngest son, Kayce Dutton (Luke Grimes), a former US Navy SEAL, first lives on the Broken Rock Indian Reservation with his Native American wife and son before moving to the Yellowstone Ranch. Bethany "Beth" Dutton (Kelly Reilly) is the only daughter of John and Evelyn. Although well-educated, highly intelligent and a master manipulator, Beth is bitter, abrasive and emotionally unstable. Jamie Dutton (Wes Bentley), an aspiring politician, is the adopted son of John and Evelyn. He was adopted after his biological father murdered his mother and went to prison.
The family fights politicians and developers to keep their land from being encroached upon, including an Indian reservation.
