Young and promising representative Yang Qixiao (Zhuang Kaixun) took over his father's hotel business and roamed the black and white worlds. Xu Ziwei (Zhang Rongrong), a former member of the special service team, was promoted due to injury on duty. A migrant worker escape case accidentally involved a dismemberment case. Xu Ziwei and rookie policeman Chen Jiahao (Liu Guanting) privately investigated and suspected that it was related to the Viper Group. However, her boss reprimanded Xu Ziwei for exceeding her authority in investigating the case and transferred her to serve as Yang Qixiao's bodyguard. Unexpectedly, the fate of the two was entangled in a hostage case three years ago... The process of solving the case, like Rashomon, made everyone unknowingly step by step into someone's carefully planned "layout".
