they discovered a living moth chrysalis. The Toxicology department identified the very rare insect as "death's-head hawk-moth." They remained perplexed as to how it got there. While doing research on the insect, Yi-Chun realizes that the face pictured on the moth bears a striking resemblance to that of the Little Girl in Red. That night, Yi-Chun struggles to get sleep, and she notices blood on her arms, soon becoming enveloped in a pool of blood before seeing the Little Girl. She then awakes from the nightmare, frightened. As Yi-Chun leaves for work, Wei's grandmother tells her that when Wei returns, she will leave the house to him. She goes on to tell that the family was well off but they lost their fortune, which is why Wei works so hard. Yi-Chun asks Uncle Kun to keep on eye on grandma before leaving for work. She makes a public radio announcement, asking for more information about the strange species of moth. Yi-Chun gets a strange phone call, and hangs up abruptly to jot something down. Outside, police interrogate a man who claims that he is going to the mountains to find "her." Yi-Chun returns home after wandering through the forest around the mountains and looks at picture of her and Wei. Yi-Chun joins a local rescue group on a mission to find Wei and his grandmother. While exploring the mountains, Yi-Chun spots Wei's grandmother, who is taken away, both frightened, telling them to "go back!" Later in the evening, Yi-Chun tells the group that a retired mountain guide, by the name of Wang Tien-Tze told her the location of her boyfriend. However, a group member tells her that he died a long time ago. In the morning, the team splits up to investigate three different paths. During the trek, she becomes lost in the woods. The area begins to fog immensely, and Yi-Chun ties red tape around some trees, blowing her whistle hoping to be found. She lights a flare after being grabbed by a mysterious hand. Just then, the strange moth in a tree opens its wings, releasing several more in Yi-Chun's direction. When she awakens, she lights another flare, while hearing a girl call out for her mother. She then encounters a multitude of dead bodies in the trees. She then looks down to see that she is pregnant and begins to bleed uncontrollably as she apparently gives birth
