In a post-apocalyptic future ravaged by overpopulation, a lone survivor mercilessly protects his remote sliver of property from intruders. When a mother and daughter in search of food and shelter show up at his doorstep, he's suspicious, but allows them in. Soon an uneasy alliance, borne of necessity, forms between the trio. But distrust and paranoia threaten to give way to violence at any moment.

Red, a lumberjack living in the depths of the woods, has sequestered himself and his doting girlfriend, Mandy, from the world. Though Mandy is a gentle woman who spends most of her time immersed in a book, she finds herself in a life-threatening situation after being kidnapped by an ill-intentioned cult leader. When stripped from her home by a group of malicious cult members, Red sets out to avenge Mandy's abrupt and inexplicable disappearance.
