A case of a teenage girl named Lu Yaoyao being raped and murdered occurred in Qin'an City, arousing widespread public concern. During the court session, Lu Ming, Lu Yaoyao's father, unexpectedly hired a top lawyer to defend the defendant Chen Xu with a not-guilty plea, claiming her death was an accidental fall from a building. This led to intensified family conflicts. Song Weiwei, infuriated, divorced Lu Ming, and Lu Zhaozhao reported to the police, suspecting Lu Ming. A year later, Chen Xu was released for "major meritorious service." Lu Ming took the entire family to apologize to him. It was then that Lu Zhaozhao discovered the four characters "请君入瓮" (Invite the gentleman into the jar) on Lu Ming's arm, exposing his revenge plan. In the end, Lu Ming shot and killed Chen Xu to avenge his daughter.
