Cheng Jie (Bao Beier), chairman of a certain group, was instructed by a "master" to have sex with a woman to change his luck. He targeted Han Mei, a "single mother" employee of his company, and raped and injured her, leaving her in a vegetative state.

Han Mei's sister, policewoman Qiu Yizhao (Jiang Luxia), firmly believed that Cheng Jie was lying and started an investigation.
