The story diversity of the chaser introduces the story of the TV series chaser 1-5.

1 episode 1 during the Japanese-Puppet War, Fu Benzhong, the leader of the underground gang, realized his identity was exposed after a seemingly ordinary conversation with Cao Refei, the chief of military operations, arranged for Tian Gang to transfer his daughter Fu Yun, and instructed Mao to inform Lao Cui to cancel the joint. Unexpectedly, the punk who thought himself a hero saved the United States was always safe, which destroyed Fu Yun's transfer plan and "saved" her from Tian Gang. Mao Zhengyuan had a premonition that this would be a mission without return. Before he left, he forced Chang Ping-an to marry Wang Xiaoyu, whom he didn't love, in an irresistible way. Everything was ready, and Cao Refei used Fu Benzhong, who had been arrested, as bait in an attempt to catch the old Cui who came to meet him. At this critical moment, Mao, who knew the secret, gave his comrades a wake-up call at the cost of his life. This scene was seen by Changping, who happened to pass by, and the mysteries in his heart emerged one after another.

In the second episode, Fu Benzhong and Mao both died in front of the clinic. Chang Ping realized that there must be a connection between them. He sneaked into the clinic late at night and found a piece of candy paper on the ground that was very uncoordinated with the on-site facilities. I didn't expect the military to come uninvited. In desperation, Chang Ping broke through the window and fled. At the same time, Cao Ruofei's gunfire rang and Chang Ping was injured in the leg. Fortunately, he met his acquaintance Mrding and escaped. The development of the situation is more and more beyond Changping's imagination. First, Tian Gang was killed by an unidentified person, and then he witnessed Fu Yun being "killed" by the Japanese. In just a few days, people around me died one by one, and Chang Ping was puzzled. What's the connection between them? What are the gunmen looking for? Why do candy wrappers appear in the clinic? There is only one place to find all the answers.

3. In the third episode, Chang Ping is convinced that Master Mao is party member. In order to find out the cause of Master Mao's death, Chang entered the driver class of Scout Station safely and smoothly after half a year. Chang Pingan began to exchange Cao Refei's trust with various positive performances. Soon, Cao Refei transferred him to the Action Section. Chang Ping-an, who has no experience in investigation and counter-investigation, began to secretly inform the underground party. The success of the first warning, like a panacea to heal wounds, strengthened Chang Ping's determination to continue fighting. However, his inexperience soon aroused the suspicion of Mrding, a special agent of the Action Department.

4. In the fourth episode, Mrding, who seems careless, is actually very cautious. Chang Ping-an's unusual attention to the "scalpel" action reminded Mrding of the night when he saw Chang Ping-an in the back street of the clinic, and even pointed a gun at Chang Ping-an to force him to confront him. In order to cover up the gunshot wound, Chang Pingan poured boiling water into his leg helplessly. Xiao Kai, a progressive young man, was unfortunately arrested. Chang Ping-an simply thought that confirming his homosexual relationship could save or bring out information, and even instructed the wife of a fortune-telling designer, Chen Kehai, to persuade Chen Kehai to stop. Xiao Kai can't just tell the unidentified Chang Ping. In order to prevent Xiao Kai from hunger strike, Chang Ping was forced to feed. This method has been appreciated by Cao Refei, but it has deepened Chen Kehai, deputy section chief's antipathy to him. Sister Gao Qi witnessed the sacrifice of her husband Tian Gang and her younger brother Xiao Kai. In anger, she decided to retaliate against Chang Ping-an privately.

In the fifth episode, the fortune teller was taken to the action part, which was not what Chang Ping-an expected. Mrding is more and more suspicious of him, and Chang Ping-an must find a way to restore his trust. He decided to take a risk, and Gotcha took action against him. Chang Ping-an succeeded. Mrding witnessed Chang Ping-an's injury, and temporarily dismissed the idea of doubt. Chang Ping regained Cao Refei's recognition by using the information of Li Tang's tryst, and was transferred to the secretarial office. Cao Ruofei deliberately avoided the stationmaster's question about marriage. When he drove to a remote villa in the suburbs, Fu Yun opened the car door.
