[2][3] A Mu moves with his wife, Le Xiaomei, who is two months pregnant, to a mountainside villa owned by his friend, A Ming.

The villa is decorated with paintings of two boys playing string game and there is also a locked room A Mu claimed belonging to A Ming.

Supernatural occurrences begin to haunt the couple, including a red doll that stalks Xiaomei, a music tape that plays a string game song, and most importantly, a ghostly woman with long hair and white dress.

After a series of boxes containing increasingly threatening messages are left at his doorstep, A Mu installs security cameras around the house.

Arriving back at home from the hospital, Xiaomei forces A Mu to reveal the truth about Qingqing, his fellow orphan and childhood friend together with A Ming.

Xiaomei visits Xiaohan at the hospital to inform her that A Mu left some money for her and Qingqing so she could pay her bills, wishing her recovery and saying that she is not alone anymore.

Yangyang sings the string game song and a hand grabs the doll before the movie cuts off.
