Horizon: An American Saga - Chapter 1

“The American saga begins this summer.”

In 1859, people are heading into the territories between Wyoming and Kansas, and nobody on the road agrees on what is out there. Kevin Costner follows several of them at once, including Hayes Ellison (Costner), a gruff cowboy on the run with a prostitute and a young boy after killing another gunman. Frances Kittredge (Sienna Miller) and the other settlers have staked everything on this land, and it is not yet clear it will hold them.
