At the funeral of her husband Luo Ye, Yun Xiu personally pinned a blood-stained brooch in front of the portrait of his late wife, but received an anonymous letter the next day - it was not his wife at all, but an escaped murderer who committed a series of murders three years ago. When Yun Xiu uncovered the case files and surveillance footage that Luo Yeye had hidden, she found that all the evidence pointed to a terrible truth: Luo Ye was not pursuing the crime, but burying it for her. She must find out whether the man who loves her deeply is the murderer's accomplice or another manipulated prey before the police round him up.
