Zhou Zheng, an installation technician, repeatedly finds his deeded parking space occupied by Zheng Hao. Reporting the matter to the police and seeking mediation achieve little. After completing the required procedures and filing the necessary notice, Zhou Zheng installs a retractable parking bollard in his own space. Zheng Hao's car gets trapped, and he makes one impulsive mistake after another, eventually smashing a charging station and causing a fire in the underground parking garage. Rather than resorting to violence, Zhou Zheng relies on evidence and the law. Right and wrong are ultimately judged fairly, delivering both a realistic portrayal of a common problem and an important lesson in legal awareness.
