The Keeping Room - Brit Marling, Hailee Steinfeld (2014)

Set in South Carolina toward the waning days of the American Civil War, it's a time of lawlessness and savage atrocities, as the Union has all but completely won the war against their Confederate adversaries. Augusta is a Southern woman living in her expansive plantation estate with her younger sister Louise and slave Mad, all of whom have to tend to the needs of the farm while the men of the town are away fighting or dead. A mishap forces Augusta to go into town to procure medicine, where her beauty draws the eye of a couple of psychopathic Union Army scouts ahead of Sherman's Carolinas Campaign who have taken advantage of the lack of protection in the land by taking what they want without concern, when they want, whether that means booze at the local saloon, or any defenseless women they encounter. If anyone fusses, they're killed, along with any witnesses, without a concern for the morality of it. Augusta manages to make it home, but the men have followed, and with no one around to come to their defense, the women are going to have to figure out a way to fend these embattled soldiers off in order to avoid a nightmarish end to their lives.
