At the last moment of Choi Eun-joo's life, she still clung to her love and protection for her son Kim Do-chi.The depth of this mother's love left an indelible scar in Jin Daoqi's heart.The death of his mother plunged Jin Dodge into deep grief. He closed himself in his room and licked the wounds in his heart alone.Until he got back on his feet, decided to step out of the shadows, and started planning for the rest of his life.

Jin Daoqi's plan is not only to clear his friend Jin Zhezhen's grievances, but also to fulfill the late Zhang Chengzhe's instructions.On this road, he met Wu Zheyong's son, Han Dongcan.Han Dongcan is an ordinary prison guard, formerly known as Wu Xiuxian. He takes care of his mother with dementia without knowing it, and at the same time he is under the pressure of loan sharks due to the high expenses of the hospital.

Jin Daoqi approached Han Dongcan as a diner, and not only defeated his creditor, but also won Han Dongcan's trust.During the conversation, Han Dongcan had a good impression of his father, but knew nothing about his father's evil deeds.This ignorance seemed especially ironic to Jin Daoqi, because he knew how many families suffered because of Wu Zheyong's crimes.

The next day, Jin Daoqi deliberately visited Wu Zheyong in prison and used Han Dongcan as a bargaining chip to threaten Wu Zheyong.Faced with the threat to his son's safety, Wu Zheyong finally understood the feelings of the victims.At Jin Daoqi's request, Wu Zheyong took the initiative to apply for a prison transfer.When leaving prison, Jin Daoqi also arranged for Han Dongcan's mother to stay in a nursing home cooperated by Jade Bird Group, and the expenses were also borne by Jade Bird Group.

However, a twist of fate caused Han Dongcan's mother to pass away on the eve of transfer.Han Dongcan, who lost his mother, was devastated, and Zhang Chengzhe saw Wu Zheyong at this time and felt his shock and grief.He never expected that the young prison guard he had brutally beaten to fractures would turn out to be his biological son.

Jin Dodge's revenge plan gradually unfolded, but in the process, he also gradually realized the complexity of human nature and the interweaving of good and evil.Kang Ha Neul came forward to save the members of the Bluebird Group and took on all the crimes, which made Jin Daoqi feel deeply conflicted.At the same time, Deputy Chief Zhao's resignation and change of career as a lawyer also allowed Jin Daoqi to see different forms of justice.

Finally, in court, Wu Zheyong confessed the crime as a witness and begged Jin Zhezhen for forgiveness.Jin Zhezhen walked out of the court accompanied by his family, while Zhang Chengzhe and Deputy Chief Zhao also regained their smiles.In the second trial, President Bai and others received the punishment they deserved, but Jin Daoqi understood that there are still countless potential evils in the world that they need to expose and confront.
