Ji Su (Jin Huixiu) is a somewhat neurotic woman, often with strange pictures in her mind, so she goes to the hospital for help. But her attending physician Xiquan (Jin Taiyu) can do nothing about her symptoms. A year later, Xi Quan and Ji Su were reunited again, and he found that she was still in a trance, trying to come into her life and help her recover. With the in-depth understanding, Jisu finally revealed her unfortunate experience to Xiquan: it turned out that she once had a beloved man, but she was in love with someone else, and at this time she was pregnant. In order to get back at the unfaithful man, Jisu made an amazing decision: during her pregnancy, she desperately got drunk in the nightclub, went crazy smoking, ruined her body, and caused the fetus to die two months prematurely. Moreover, the cold-blooded she also has more extreme behavior, which makes Xi Quan helpless. It was not until he solved the mystery of her life that he was surprised to find that everything was vengeance, and all the crimes originated from the big mistake she had made on impulse.
