What happens in Horizon: An American Saga: Chapter 1?

In 1859, two surveyors draw lines in the desert to mark the place they intend to call home in Arizona’s San Pedro Valley. Soon, this’ll become a settlement called Horizon. But is this land really theirs? A few years later, an Apache tribe — among them, leader Pionsenay (Crow Shoe) — sets the town ablaze, killing a majority of the settlers in a violent raid. Those who survive, like mother-of-two Frances Kittredge (Miller), must now face the harsh reality of finding a new place to call home. Elsewhere, Ellen (Malone) outruns her violent past with her infant in tow, as dangerous brothers Caleb (Campbell Bower) and Junior Sykes (Beavers) attempt to track her down.
