Back to three days ago, when trying to save his father (EU), Sergeant Xin Jian (Zhu Qianxue) was patrolling a village in the early morning, he met several suspicious elements and chased them. However, due to the obstruction of Guan Dingming (Wang Haoxin), the village head, the incident intensified and a gun battle was triggered. Chen Feng's father, Ling Hai (Luo Lelin), unexpectedly appeared at the scene of the gunfight and died of stray bullets. Chen Feng blames herself! Morning wind encounters a cosmic illusion in pain, so that she can go back to three days ago and have a chance to save her father! Chen Feng thinks he knows everything and it's easy to change things. In fact, these three days let her see the truth behind the incident, and because of the butterfly effect, it is not as good as the first time, Linghai is still doomed to death. I returned to the morning breeze that forced me to save the enemy and learn from them. I went back again, acted cautiously, and finally succeeded in saving my father. At the same time, Chen Feng found that there were black policemen in Zhai village, which was not good for the villagers. She also learned that there was a front-line person lurking in ICAC to investigate the crime of collusion between criminal groups and black police so that she could return three days ago. Chen Feng once again met Ming Ding, the "father killer", and realized the other side of his personality. Seeing that Ming Ding was facing a life-and-death crisis, police officer Chen Feng tried his best to rescue him. In this process, Ming Ding and Chen Feng are forced to cooperate to find out the village's black police. Their personalities and styles are very different, and there are many contradictions and conflicts in the process of communication. I kept going back and forth for three days to see the morning breeze of my comrades-in-arms and friends, and I seemed to know more about the people around me. Chen Jinwei (Dan Liwen), the commander of the emergency forces who often has nothing to do with Chen Feng, was accidentally discovered by Chen Feng. The two of them appreciate each other and are also teachers and friends. Enemies can become friends, and boyfriends and girlfriends can also turn against each other! Guo Shangzheng (Yuan Weihao), a boyfriend and comrade-in-arms, found that the morning breeze was getting closer and closer to Ming Ding, which seemed to spark love and caused waves in the relationship between Shang Zheng and the morning breeze. In addition, when the morning breeze returned to the past, it found a secret that was still a bolt from the blue, almost collapsed, and its attitude changed greatly, which also dealt a heavy blow to the morning breeze. He Zhanxiang (Lin Wei), a well-known local tyrant squire in the New Territories, is an intellectual and charity businessman on the surface, and deeply attracts Chen Feng's reporter friend Li Ziting (Tan Kaiqi). Chen Feng found out that Zhan Xiang was involved in illegal activities and learned that Ziting and Shang Zheng had a one-night stand. Seeing this "good friend" approaching Zhanxiang on his own initiative, he is caught in the eye of the wind and may even betray another close friend, He Xiaomei (Liu Peiyue). A series of doubts plunged Chen Feng into a painful struggle ... The ability to cross the past brought painful pressure. Chen Feng has the super ability to go back to the past, which allows her to pull her father back from the brink of death, but at the same time, she can also see the stories behind people around her and all kinds of unfortunate experiences that happened to them. More importantly, let Ding's name stop acting recklessly, which made Chen Feng realize that the greater the ability, the greater the responsibility. Chen Feng gave up the idea of going back to the past, but wanted to lend a helping hand to the person he loved in front of him. How did Chen Feng face this painful choice?
