Late at night, Wang Xinyao trembled and called the police, claiming that her home was haunted. When detective Mu Yanagizawa led his team in, he only saw her mother's cold body in the living room. There were no signs of intrusion by outsiders. What's even more bizarre is that the surveillance footage showed that Wang Xinyao forced her mother to put her daughter into the washing machine and placed a sharp blade in it. However, the lie detector test confirmed that what she said was true. Is all this a delusion of insanity, or is there something else hidden behind it?
During the psychotherapy process, Wang Xinyao was shocked to discover that her husband Liu Zemu had passed away three years ago - in an accidental car accident while saving his mother. After she became the caregiver of Li Cuihe, an elderly man living alone, cracks began to appear in her memory. Li Cuihe continued to exert psychological hints, which made her dislike her mother day by day until her mother died suddenly.
As the investigation deepened, Liu Zemu discovered that Li Cuihe was actually the mother of the driver responsible for the accident, and she was also a messenger of revenge who was proficient in hypnosis. She used drugs and hints to weave layers of traps into Wang Xinyao's memory. When the truth gradually emerges, Wang Xinyao not only has to face the tampered memory, but also contends with a split personality, looking for the only way to survive in the confusion between reality and illusion. And how will this three-year revenge plan finally end?
