In the fictional future world, the female protagonist Li Anran personally brought her father Li Hanxin to court and invented memory retrieval technology specifically to expose Li Hanxin's past crimes and make him accept the appropriate punishment The trial began, and the jury and everyone learned that Li Hanxin and Li Anran had a father daughter relationship. They were puzzled as to why the daughter hated her father so much. Li Anran explained that he should not be deceived by Li Hanxin's appearance. He is actually an unforgivable scumbag and accused Li Hanxin of domestic violence against his wife in front of him when he was six years old. As the memories of domestic violence were extracted and played on the big screen, people also saw the scene of Li Hanxin domestic violence against his wife and thought that he was just a scumbag as Li Anran said. However, with the disclosure of later memory images, it turned out that Li Hanxin was willing to sell blood to raise money for his daughter's medical treatment. His wife was worried about his health and stopped him from going out. During their push, his wife accidentally bumped into the wall. The young Li Anran saw this scene and mistook it for Li Hanxin's domestic violence against his mother Li Anran continued to accuse Li Hanxin of his crimes. His former mother's leader, Uncle Zhao, came to donate money, but was beaten by Li Hanxin without reason. But as this memory is extracted, there is another hidden truth behind it. Originally, Uncle Zhao used the excuse of donating money to the young Li Anran to seize Li Hanxin's wife. After being rejected, he became even more embarrassed and angry, and spoke ill of him. Li Hanxin couldn't bear it anymore and then took action to teach him a lesson Li Anran saw that the first two accusations were unfounded, so he accused Li Hanxin of killing his mother, causing a commotion among the crowd. Immediately after, he saw a memory of Li Hanxin killing his wife, but the scene lacked the process of the attack. Li Anran believed that this was enough to convict Li Hanxin of the death penalty and requested a jury vote. The jury had different opinions and believed that there was no specific process of murder, which could not prove that Li Hanxin killed his wife. In the end, the vote was tied, and Li Anran voted guilty. The presiding judge was preparing to read out Li Hanxin's death sentence when Su Wen, the president of the Su Group, appeared and called off the trial Su Wen told everyone that Li Hanxin is not a murderer, and there are hidden reasons for the truth, but it cannot be said. Everyone questioned Su Wen's identity as CEO, and Li Anran told everyone that Su Wen was actually Li Hanxin's lover. It was Su Wen who caused her parents' divorce back then, so Su Wen spoke up for Li Hanxin As memories are retrieved, people see the events of that year. Li Hanxin issued a divorce notice to his wife without any reason. His wife took the young Li Anran to a nightclub to find Li Hanxin, and caught him holding Su Wen and coming out of the private room. His wife approached and questioned him, and Li Hanxin admitted calmly that Su Wen was his new lover People criticized Su Wen one after another, but Su Wen was unable to defend herself and let everyone continue to look at their memories to find out the truth. It turned out that Su Wen was tied up in a nightclub by thugs. Li Hanxin used his crush on Su Wen as an excuse to take her out of danger. By chance, he met his wife who came to look for her husband. In order to prevent her from also being in danger, he had to use harsh words to force her to leave. Afterwards, in order to repay Li Hanxin's life-saving kindness, Su Wen agreed to be his intermediary and provide intelligence about the criminal organization to the police, ultimately leading to the complete destruction of the criminal organization As the truth gradually revealed, everyone finally understood that they had misunderstood Li Hanxin. But Li Anran believed that Li Hanxin's provision of intelligence to the police was just a dog biting dog within their criminal organization, using the police's hands to eliminate dissidents. This does not necessarily mean that Li Hanxin is a good person, as he once tried to take his own life In the memory scene, Li Anran's uncle had his leg broken by Li Hanxin because he was raising her. However, the truth is that the uncle used Li Anran's child support to gamble on debt and wanted to sell the young Li Anran to pay off the debt. Li Hanxin discovered the situation and broke her leg People believe that Li Hanxin cares about her daughter, but Li Anran exclaimed that it's impossible. If Li Hanxin really cares about herself, why did she try to sell her organs In the memory scene, the young Li Anran hid in a dark room, listening to Li Hanxin and the doctor discussing the health of Li Anran's kidneys outside. However, the truth is that Li Hanxin was willing to transplant her own kidney in order to keep her daughter alive, and this conversation was mistaken by Li Anran for selling her organs Li Anran, who was in a state of collapse, couldn't believe the fact in front of her. She couldn't believe that someone she had hated for twenty years had done everything for her daughter. As Li Hanxin's last memory was revealed, the truth was revealed Twenty years ago, Li Hanxin took the initiative to become an undercover agent to treat his daughter's illness. In order to avoid implicating his family, he proposed divorce to his wife. During the undercover period, he provided intelligence on criminal organizations to the police through Su Wen, while always keeping his daughter's growth in mind. And his wife's death was actually due to Li Anran and his classmates showing off their father's identity, which was heard by members of a criminal organization. They forced Li Hanxin to kill his wife and daughter to prove that he was not an undercover agent. Li Hanxin originally planned to escort her and daughter to escape, but was intercepted by the criminal organization. After learning the truth, his wife sacrificed herself to protect Li Hanxin. Li Hanxin deliberately deceived Li Anran that his wife was killed by him, only to let his daughter live well with hatred towards him The truth was revealed, and Li Anran was filled with regret. Only then did she realize how great her father was, who had suffered a full twenty years of injustice for his daughter. Li Anran knelt in front of Li Hanxin and shouted out the "dad" who was twenty years late
