Mr. Wu, a Hong Kong movie star, is kidnapped in Beijing by Zhang Hua's gang. The police quickly form a task force and begin the search, ignoring that detectives in charge have only twenty hours before the deadline.

Ji Hong, a sanitation worker, is desperate to secure a school enrollment spot for her child. She finds herself subjected to inappropriate advances disguised as "jokes" by her supervisor at work. While her colleagues turn a blind eye to such behavior, the stubborn Ji Hong resolves to fight back.

Detective Ji Bai and new criminal profiler Xu Xu may seem like an awkward teacher-student pair at first glance, yet they are actually the best partners in the police force, solving one crime after another. Ji Bai slowly falls in love with Xu Xu, yet she is a girl who is as slow as a snail when it comes to love. Just as Xu Xu starts to reciprocate Ji Bai's feelings, the dormant "Angel's Killer" reappears.
