Plot
Psychiatrist Dr. Gao Jing is scuba diving with a group of environmentalists attempting to bury carbon dioxide in the seabed when she is photographed by Guo Dong, the brother of her patient Xiao Kai. The photographs are shown in an exhibition and the two begin dating. Guo Dong takes Gao Jing to the Ryukyu Islands to show her the ancient underwater city of Yonaguni where he has hidden a ring that he will use to propose to his true love, but is beheaded in a mysterious accident.
Xiao Kai does not believe that the body at the funeral is her brother's because there is no head and the fingerprints have worn off. She believes that her brother may still be alive and begins searching for him. She searches a shipwreck site with Guo Dong's friend Haiya Amu and finds a white-haired severed head that she believes to be her brother's.
Dr. Gao has lost her memory of the events and does not know what happened to her boyfriend. Dr. Gao convinces her boss Dr. Tang to give her hypnotism therapy and drugs to recover her memory. The drugs cause her to develop a sensitivity to bright lights and loud noises. She notices the same sensitivity in her patient Simon, who says he has seen the dripping wet ghost of Guo Dong. Dr. Gao asks Simon to help her contact Guo Dong but warns her that she is being pursued by the white-haired ghost.
