Located in an isolated area in the middle of the forest, Pauls ancestral home seems the ideal spot for a quiet stay and the chance for Lucy and Norman to sort out their emotional problems. However, their peace is shattered when Paul and Norman discover a cabin in the forest in which a girl with ectrodactyly is imprisoned. Their attempts to take the girl to the police are hindered by the difficulties of the heavily wooded terrain and the intervention of a group of villagers who are determined to keep the girl locked away for good.
