While Eun-soo is driving along the back roads to get to his sick mother's bedside, his very pregnant fiancée berates him for leaving her when she could give birth at any moment. Distracted, he loses control of his car when he nearly drives over a dead animal on the road. He finds himself stranded in the middle of the forest. A young girl finds him and takes him to her home, where he's met by two other children and their parents, who take him prisoner.
