The film received funding from Taiwan's Bureau of Audiovisual and Music Industry Development and stars Hsu Wei-ning, River Huang and Liu Yin-shang.

Property agent Wei (River Huang) lives with his grandmother (Liu Yin-shang), but one day she suddenly disappears when she is apparently abducted by someone or something.

Wei visits his Uncle Kun (Po-Chou Chang) and finds out that the camera that was mailed to him belonged to his Aunt Shui.

While searching the premises with his uncle, a loud crash is heard and a stereo system starts playing music before a door is slammed shut.

Uncle Kun shows Wei and Yi-Chun video footage of the day his grandmother went missing.

He appears to hear whispers which seem to guide him around the house, and he follows a trail of blood back to the kitchen.

One night during her shift, Yi-chun takes a mysterious call, and the caller quietly repeats, "He doesn't love me anymore," before hanging up.

Meanwhile, at the house, Uncle Kun and Yi-Chun perform what seems to be a blessing over the home, shouting at the ghosts to go back where they came from.

Later that night, Yi-Chun does research involving the mountain, and stumbles across a video, explaining that 'mosiens' cause people to lose their minds.

The video also explains that setting off firecrackers and other explosives, can remove the evil, making a home habitable once more.

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.

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.

The area begins to fog immensely, and Yi-Chun ties red tape around some trees, blowing her whistle hoping to be found.

As they attempt to escape, she trips and falls, as the Little Girl in the Red Dress bounds her with tree branches.

The girl transforms into a hideous creature and begins to choke Yi-Chun, as she recalls memories of her and Wei.

A beam of light wards off the evil creatures, and she returns to Wei, before she is carried away by the other members of the rescue team.

A death's-head hawk-moth flies over to a wall hinting that Yi-Chun never escaped the forest and is still trapped there in an illusion.

Hsu Wei-ning and River Huang reprised their roles, with Rainie Yang, Francesca Kao and Lung Shao-hua joining the cast.
