Li Jinping, Sun Gang, Zhao Yunfei, and Chen Yuting's team began to search for enemy agents lurking in Chongqing. Li Jinping met Zhao Meigui, a hidden Kuomintang agent. Li Jinping told Zhao MeiGui that Shi PeiYing sacrificed for the party country and he wanted to avenge Shi PeiYing. Zhao MeiGui immediately said that he could introduce him. As long as they persisted for three months and waited for the national army to return, they would be considered senior officers. Li Jinping quickly caught the fish, and Zhao Yunfei and Chen Yuting were not far behind when they saw this, and soon discovered Lu Ning, a big fish. Lu Ning knew Chen Yuting, so Zhao Yunfei asked her to hide first and went forward to test it out.
Zhao Meigui took Li Jinping all the way up the mountain, and Zhao Yunfei found a restaurant and pretended to have a meal to observe the cover, but the boss also noticed something was wrong. Zhao Meigui took Li Jinping into a village, where there was a small thatched house, and there was a small institution inside. Li Jinping was a little skeptical, but followed Zhao Meigui into the bunker, met other spies, and became a member of the action team. Li Jinping wanted to go back and report to them first, but Zhao Meigui said that he could not go out without completing the task.
Zhao Yunfei and Chen Yuting followed Lu Ning and found another stronghold of theirs. The two led a team, and Sun Gang led the other team to arrest the stronghold. Zhao Yunfei and Chen Yuting arrested all members of Lu Ning's team. Zhao Meigui wanted to take two people to find the blasting target. Li Jinping was left behind, so he could only find the villagers to help pass the note while looking for supplies. Zhao Meigui came back with a big box full of heavy machine guns and several machine gunners. Li Jinping never expected that the little girl he asked someone to send the letter to was also from Zhao Meigui. When Zhao Meigui was planning to take someone away, Sun Gang arrived in time, and Zhao Meigui's plot went bankrupt. It turned out that the machine gunner that Zhao Meigui brought back was also sent by Sun Gang to act.
The reconnaissance operation came to the final result. The person in charge of going out to the enemy was Cheng Shiru. They formulated the Jin Falcon plan. In order to get the lurking list and wipe them all out, the organization decided not to arrest Cheng Shiru for the time being. Zhao Yunfei and Chen Yuting sneaked into the enemy's interior to execute Task. In order not to arouse Cheng Shiru's suspicion, the organization decided to ask Zhao Yunfei and Chen Yuting to give him a big gift, and let them pretend to put on a scene of robbing the death row prisoner, and this person is also their old acquaintance. Cheng Shiru also learned that she had been arrested, she knew too much, she must silence her when necessary, and this person was Zhuang Meijiao.
On the way Zhuang Meijiao was escorted, Cheng Shiru had already arranged for someone to kill him, and Zhao Yunfei and Chen Yuting acted out a robbery scene. Zhuang Meijiao knew that the person who shot just now was one of them, and she knew too many secrets about Moire. Soon Cao Shun also showed up, and he took them to meet Cheng Shiru. Zhao Yunfei and Chen Yuting said that they had the blood of the Communist Party on their hands, and they had to return to Chongqing. Zhuang Meijiao didn't become suspicious because they saved her with their own hands.
