1949 12, Shanghai was liberated, and Chen, the head of Shanghai's big spy, was lurking there in order to destroy Shanghai.

The security, finance and market order of the Flying Tiger Condor (7 pieces) have formed a huge underground enemy spy organization "Guangfu Society". At that time, only a few months after the liberation of Shanghai, the RMB had just been put on the market. Because the broad masses of the people were devastated by the KMT's golden coupons, they did not believe in the credit of the RMB. In order to promote the circulation and use of RMB, silver dollars and counterfeit banknotes are the biggest enemies. After Chen came to Shanghai, he was keenly aware that this was an available opportunity. On the one hand, through the relationship of the former military government in Shanghai, he secured a large number of big speculators in old Shanghai and manipulated the black market trading of silver and yuan. These people buy low and sell high. Within a few days, the price of silver rose from 600 yuan to 2,800 yuan, causing market chaos and soaring prices. On the other hand, Chen led his spies and gang members to counterfeit RMB and put it on the market, which made the already chaotic market worse. In the eyes of the masses, the RMB has almost become a replica of the golden certificate. The market is chaotic, prices are changing three times a day, and the daily life of the broad masses of the people is not guaranteed, especially the working people at the lower level have no food and clothing. The situation can be said to be extremely critical. In order to cope with the critical situation and smash the sabotage activities of the Guangfu Association, the Shanghai Military Management Committee ordered the Public Security Management Committee and the underground party to do everything possible to resolutely smash the enemy's conspiracy, restore Shanghai's financial and market order as soon as possible, and protect people's daily lives. After receiving the order, the Governance Committee and the Working Committee quickly set up the "Liu Tie Action Group", headed by Gu Ren, director of the Public Security Management Committee; Zhang Qiao, deputy director of Old Underground party member, served as the team leader. In view of Yan's rich experience in fighting against the enemy, Zhang Qiao specially transferred him from Chongqing to Shanghai to infiltrate the enemy with his skill. The two agreed that only Zhang Qiao knew Yan's identity, that is, one-way contact, and Zhang Qiao was responsible for using our party's relationship in the gang to put Yan's "Flying Tiger Condor" poster.

Shuang Ying became the apprentice of Jin Jiuling, the leader of "green gang" who fled to Hongkong after liberation. As a result, Si Tian scout Yan became the boss of green gang and escaped from prison. Zhang Qiao forged all the legal documents of Yan's imprisonment, and gave the rest to Yan, who took off his military uniform and hung out in dance halls and casinos. He soon conquered the young green gang with his high-energy martial arts, and then fought for the metropolitan dance hall controlled by Guangfu Society, openly fighting with Chen, fighting several times. Chen and his men were afraid of him, so they took the initiative to negotiate with him and asked Yan to join the Guangfu Association. In this way, Yan became the vice president of Guangfu Association as green gang's eldest brother. However, things didn't end there, and the cunning Chen's temptation to Yan followed. First of all, he gave Yan the wavelength and frequency band of the underground radio station used by the underground mold factory, and secretly observed Yan's reaction. Sure enough, Yan was overjoyed and handed the wavelength and frequency band to the group leader Zhang Qiao. Soon, Zhang Qiao found the location of the underground mold factory. Just after the arrest began, the alert Yan suddenly discovered that this was a trap. At the critical moment, he managed to inform Zhang Qiao and cancelled the operation at the last minute. After many temptations, Chen finally trusted Yan completely. However, at this time, unexpectedly,

The stills of The Flying Tiger Condor (10) took place. Due to the betrayal of the spies in Liu Tie's team, Zhang Qiao returned from Nanking and fell into the hands of the enemy. Chen handed him over to Yan for disposal ... At the critical moment, Zhang Qiao jumped on Yan, pulled out his pistol, aimed at himself and pulled the trigger ... Face to his old superiors and old friends, want to cry. He vowed to make the enemy bleed! In the end, with superhuman wisdom, he dug up the mole, found out the list of silver dollar speculators, cooperated with the organization to crack down on the counterfeit banknote printing factory in one fell swoop, completely shattered the enemy's plot, and wiped out the hidden enemy spy headed by Chen.
