A gruesome yet bizarre murder occurred in Hong Kong where a social worker surrendered himself after brutally murdering his family. Forensic psychiatrist Xu Xiao Jing (Stephy Tang) finds a linked case through her ability to “see” into people’s unconscious and suspects that another psychiatrist, Ren Chong Guang (Tse Kwan Ho), instigated the murder. Along with police inspector Ah-Fa (Philip Keung), Jing investigates the murders and chances upon yet another cruel murder – where the victims are elderly folks who had their skin flayed and hung up. As the investigation comes to a dead end, Jing too becomes a suspect.
