Humans are few and far between since Earth was invaded by unseen extraterrestrial machines that harvest the planet's natural resources and relentlessly kill its inhabitants. In a remote part of the countryside| where starved humans have become as dangerous as the alien machines hovering in the sky| a feisty 19 year old girl| Sarah Connolly| sets out on a desperate attempt to fight back a group of bandits and defend her parents' farm| their remaining livestock| and the solar panels that keep them safe from extraterrestrials. If she doesn't succeed| she will lose her only source of food and shelter; but if she resists| she and her helpless blind sibling will be killed. And if the mysterious intruder dressed like a soldier who claims he can help them turns out to be a liar| then the enemy may already be in the house.
