Her name is Fang Lei (played by Zhou Xianxin). She is a surgeon with beautiful appearance and outstanding professional skills. She lives a meticulous life and even has a bit of overly sensitive cleanliness. But under her glamorous appearance, she has pain that is difficult for people to confide in. Whenever night falls, the nightmare that has troubled Fang Lei for many years comes as promised. In the dream, a woman in white follows Fang Lei and calls her name in a shrill voice. All this makes her miserable. One day, Fang Lei reunites with her friend Angela (played by Gillian Chung) from her school days and her husband, Zhou Lei's first love boyfriend Zhou Feng (played by Wu Jianfei). When old friends and old loves meet again, different feelings quietly grow in the hearts of the three people, but they don't know that danger is approaching step by step.

Behind the truth is a terrifying and sinister conspiracy and a human heart full of ugly desires...
