Wang Laoshi (played by Ding Yongdai), a police officer in a city in the southwest, has always been brooding over Liu Chuan (played by Huang Jue), a bank thief who escaped five years ago, and vowed to capture him personally. Liu Chuandong has been hiding for several years. For the sake of his daughter, he sneaked back to the small town again, but met Officer Wang unexpectedly. The two started a life-and-death chase. At the moment when Wang Laoshi captured Liu Chuan, the ground shook and the whole city collapsed. Liu Chuan, who woke up, changed into Wang Laoshi's police uniform for convenience, but he didn't expect that this police uniform would make him trapped in the rescue and unable to get out. The rebellious girl Qin Xiaoxiong (played by Ruby Lin) fell in love with Liu Chuan because of his bravery. As the rescue deepened, Liu Chuan seemed to have forgotten his true identity and really regarded himself as a policeman for a while. The appearance of police officer Wang Laoshi broke his dream.

At the critical moment, the two temporarily put aside their grievances and joined hands to rescue, but they each had their own thoughts.
