Mei Yingxue was an in-depth investigative reporter for "Metropolitan Daily". On New Year's Eve when she was ten years old, her whole family was exterminated in Mei's house. Twenty years later, she discovered fragments of the truth - the murderer was a serial killer organization codenamed "Dark River", and her boyfriend of three years, Lin Shen, was a core member of the organization. With deep-seated hatred on one side and deep-seated love on the other, she chose to use her identity as a reporter as a knife and use herself as bait to step into the dark river.
