The Incredible Truth

An artist named Jia Jia promised to show her boyfriend, Wei Ling, around Japan but eventually fails to show up for no reason. After Wei Ling goes and gets accommodated in a family-run hot spring hotel of Shimizu, Jia Jia’s Japanese boyfriend, she brings her endless weird experience as if she’s haunted, and the hotel even sinks into a series of horrible homicides, in which the victims are all members of Shimizu’s family. Every clue found is connected to Jia Jia. Shimizu’s servant Tadao begs Wei Ling to help them discover who the murderer is - but, whether Jia Jia is dead or alive, along with the identity of the murderer, remains a secret, until the very end.
