The children of a rural cult decide to open a locked door that their families have sworn to protect. Opening the door unleashes The Brute, a terrifying, supernatural creature. The monster devours Ben, the boy who opened the door, and quickly goes on a rampage through the compound, picking off cult members one-by-one. Carrie, the last child alive in the cult, manages to close the door, but not before losing both parents and her left arm.
AD rescues Carrie, the titular girl in the woods, who helped unleash The Brute. Seven years later, adult Carrie thinks back on life with AD and the fateful day the Brute got loose. AD trains Carrie to defend herself against The Brute and reminds her never to open the Door. When she's ready, he gives her a new arm that he has constructed out of metal, with a special blade made of material mined from the ground near the Door. With this blade, Carrie can defend herself against any of the creatures that come from the “wound” behind the door, including The Brute.
